INSTALLATION KIT MADLEXXCARS VAZ 08-15 KIT (MLC VAZ 08-15 KIT) for cars of the Volga Automobile Plant (AvtoVAZ) ========================================= ======================== Designed for the installation of REAR DISC BRAKES (RDB) with a mechanical parking brake on vehicles with a DRUM BRAKE SYSTEM (RDB).
Brackets (MLC VAZ 08-15) are installed between the beam and the axle (rear axle) using high-strength fasteners.
As a result, WITHOUT SIGNIFICANT CHANGES IN THE DESIGN (replacing the beam or welding work...), the beam without brackets “WITHOUT EARS” is modified into a unit READY for the installation of new brake mechanisms (BRAKE CLIPS and CALIPERS).
When developing the MADLEXXCARS VAZ 08-15 KIT (MLC VAZ 08-15 KIT) for AvtoVAZ cars, we relied on the experience of other manufacturers of similar disc brake systems.
But unlike them, WE DID NOT USE exclusive and custom-made components, but selected AVAILABLE and COMMON factory parts for our system. From popular and frequently encountered car models (original spare parts and analogues, which are easy to find on sale anywhere.) So that by installing our HTD kit, car owners will not experience absolutely any difficulties in the future with the selection of consumables or repairs.
Calipers, brackets and pads are used from time-tested TRW REAR DISC BRAKE SYSTEMS. (installed on the rear axle of cars similar in weight and dimensions to AvtoVAZ models) Parking brake cables are used from the SPORT model Brake “non-ventilated” 4x98 mm brake discs are selected according to parameters from FIAT/ALFA/LANCIA Additional mounting holes are provided for installing dirt-protective shields from the front axle of VAZ: 2108/09/099/13/14/15
The result was a SIMPLE, CLEAR, COMMON and RELIABLE brake system (BS) for the rear axle with a mechanical parking brake at an adequate cost. __________________________________________________ Applicability:

Domestic cars are reliable and quite durable, despite the fact that they are widely criticized. Low cost and availability of components are the key points when choosing a machine. But every driver tries to improve his iron horse, so for beauty and reliability they often install rear disc brakes on the VAZ-2114. Yes, it's beautiful - drums look poor on alloy wheels. And reliably - the effectiveness of the brakes increases several times in comparison with the standard equipment of the car.
Basic information
Since the release of the first car at the car plant in Tolyatti, and this was the Zhiguli-2101 model, popularly nicknamed the “penny”, almost to this day the brake system diagram of all cars has remained unchanged. Discs were placed in front, and drums in the back. This is logical, since the main load during braking falls on the front ones.
Of course, this scheme is much more effective than the GAZ-24, which has drums in a circle. Because it’s no secret that disc brake pads grip much better, and the distance to stop is correspondingly much shorter.
pros
Let's look at why disc brakes are better than drum brakes:
- Braking becomes more reliable, braking distance is reduced;
- Braking forces are distributed more evenly, given that the VAZ 2114 is a front-wheel drive car;
- There is an effect of faster response after pressing the pedal;
- Unsprung masses are reduced;
- Heat dissipation occurs better, which is especially important when driving on a mountain road or during active acceleration/braking. For this reason, the brake system is cooled better;
- Disk ones are much easier to dismantle and replace;
- There is no need to adjust the handbrake after each repair of the rear brakes, although this will have to be done the first time;
- They do not freeze in winter after washing, like drum ones;
- Rear disc brakes installed on the VAZ 2114 are much more convenient to control and promptly notice pad wear.
Tuning VAZ-2114
VAZ-2114 is a fairly recent model that replaced the famous nine. The base of the cars is the same, even such little things as taillights cost the same. But you can significantly improve the car only on your own.
It is worth noting that the Lada Kalina is the first model on which disc brakes are installed on the rear axle from the factory. And it should also be mentioned that you make all changes to your car entirely at your own peril and risk. Intervention or modification of the design, steering, or braking system is punishable by removal of license plates and prohibition of operation of the vehicle. But if this doesn't scare you, you can continue reading.
Examination
Having carried out all the above operations - first on one wheel, and then on the second, you also need to check the system for leaks. The first phase is to simply press the pedal.
The fact that everything is done normally is indicated by the fact that the pedal is pressed with force, quite tightly.
But this is not enough. Have someone else press the brake pedal while you try to rotate the parts that make up your new rear disc brakes.
If nothing moves, it means that your VAZ 2114 now has new rear disc brake systems - better and more reliable than the previous ones.
What is needed for tuning
If you still decide to install rear disc brakes on the VAZ-2114, you need to know what elements are required for this:
- Brake discs. Ideally suited are those installed on the front wheels of the VAZ-2114 or similar models - 2108, 2109. Their diameter should be 240 mm. But you need to pay attention to the fact that you cannot do without a turner - the hub is slightly different in design. More specifically, it will have to be bored from a diameter of 58 mm to 60.
- Calipers, brake pads, hoses - also from the front brakes of the Samara-1 and Samara-2 generation models. Therefore, you can safely purchase the entire set of front brakes for the nine.
- Plates for fastening calipers. You can either make them yourself or purchase them at auto stores.
- 12 bolts M10X1.25, 30 mm long.
- Distance washers – 8 pieces. Ideally suited are those installed in the gas distribution mechanism drive of the 8-valve VAZ-2109 and 2114 models.
Well, that’s all, all the spare parts have been purchased, all the necessary tools are available. All that's left to do is carry out a complete modernization. It should be noted that fairly new VAZ-2114s (their price on the secondary market remains high) do not have rear brakes, but can be converted without much difficulty.

In the morning, with a sore head, I trudged into the garage with the thought (what a banana the handbrake doesn’t hold), but oh well, the store-garage route has not been canceled =) I pulled it into the garage from the store, started looking, pulled it - it doesn’t hold (the thought flew through my mind “ what the heck?), climbed further along the chain of events. After the 2nd bottle of beer, a thought clicked in my brain (100% will be good for the pads, because the brakes were very light), I threw off the wheel at the speed of sound, unscrewed the guides and angrily swore at the fact that I didn’t buy a puller to remove the drum, well I had to do occupational therapy with a sledgehammer)) 2 hours of torment and long live horror)) the work on the drums was simply unearthly depth (3mm collar) with the idea of installing new drums, a set of pads and a brake cylinder, I finished it right away! It makes sense to invest so much money when half of the spare parts from 21099 are lying in the garage (inherited from my father-in-law) I rummaged around and found the required front calipers assembled) fermented in the WD for an hour and started unwinding, untwisted, went through the bracket and painted it in the color of the front ones (light green) so as not to be rusty)) the brake discs were cockroached by a turner, to be machined for the inner landing diameter of the hub (59.8 mm), I sharpened them and went online to find what I was looking for, namely the adapter faceplates for disc brakes) more than one was killed evening in search, but! long live the miracle! what I was looking for turned out to be right under my nose (3 stops on the trolleybus) I came running, all washed up with a gas mask to the advantage, to that same treasured store with spare parts aaaand... then the bird “OBLOMINGO” (maybe you know this one) visited me, the seller Pavel Sh. says that You can order such faceplates from them, but the delivery time is 2-4 weeks, what should I do? I order faceplates, but without despair I put my skis in the treasured garage and diligently begin to twist the hubs, a long, tedious process, but with beer and music it’s still more fun) after I finally twisted the hubs, a small question arose, namely how should I unscrew 2 bolt for fastening the support disk (on which the pads and cylinder were attached) on the bolts, where I later found out there should have been a cross for a screwdriver, which I did not find, but instead I saw something that most likely should have resembled it (thanks to the previous owner! ) well, “the grinder is the best friend - said the cutting disc to the support”, with the help of simple movements, he ground the head of the bolts to an unrecognizable shape and with the calmest soul knocked the hub out of the support disc, then there was a lot of WD, mat and pliers (obscene language) they unscrewed, were happy, got drunk with joy) several days passed (I won’t name the number, because I’m afraid to lie) my long-awaited transition faceplates arrived, flying from the store to the garage at the speed of sound, bypassing the store (which I later regretted), I began installing the faceplates and... as always, maliciously I cursed and realized that I forgot to buy the bolts that were written about in the installation guide, what should I do? I had to go to the store and look for bolts, which ended up taking 2 days (since a bolt m10x1.25x30 is a rare thing), I found and took the last ones from a guy in the market for 20 rubles apiece (12 in total), bought 4 tensioner pulley washers Timing belt, thinking I’ll do one side first, then I’ll move to the other, if necessary, I’ll buy more (luckily there are enough of them everywhere), crawling into the garage I install it, after straightening the rear beam with a sledgehammer on one side of the hub, then I put on the brake disc and throw on the bracket for fitting and O miracle! my instincts did not let me down, I put 1 tensioner washer under the bracket bolt and, rummaging through the supplies, another one 2mm thick, screw it on and voila! The ZDT is installed, the only thing left is to screw on the brake tubes, realizing that they are too long, I go to the store and buy 2 smaller tubes (in my case from the sorcerer to the beam from the 10 VAZ model), I bleed the brakes with a friend and put the faceplate on the second side in in a leisurely manner. Of course you ask, what about the handbrake? My answer to this question is simple, you don’t have it in this configuration, therefore you need to install a hydraulic one, but that’s a completely different story)))) To use the information material on installation, I went to the Internet, THANK YOU to the Author for describing it in such detail installation of the HDT, low bow to you) www.vazclub.com/vaz/2108-…ad-diskovih-tormozov.html

Disassembling the unit
Before disassembling the entire brake system on the rear axle, the fluid must be drained. To do this, unscrew the bleeder fittings located on the calipers. Therefore, in the future you will have to pump it. The initial work looks like this:
- Loosen the cable and move the pads together. Unscrew the guide pins that secure the drum to the wheel hub. If you cannot remove the drum easily, generously coat the seat with WD-40 penetrating lubricant. It should always be at hand when carrying out such repairs. Even more - in advance (about half an hour) all threaded connections should be treated with this liquid.
- Remove the springs using a flathead screwdriver and remove the spacer bar. By disconnecting the handbrake cable, you can completely dismantle the old, now unnecessary, pads.
Please note that now you will not have a handbrake (unless you install a hydraulic one). Therefore, absolutely all components that in one way or another relate to the cable, including it, can be removed. Now we need to talk about installation.
Necessary materials
If you decide to install the HTD yourself, then you will need the following materials:
- Directly disc brakes, machined under the hub by 0.6 cm. The diameter of the disk should be 24 cm. Please note that it is not necessary to grind the disk itself. If you want to leave it unchanged, then you need to groove the hub.
- Front calipers and hoses.
- Faceplates necessary for attaching calipers. You will have to tinker with this part, since it is quite unusual and requires separate manufacturing to the exact dimensions.
- High quality pads that fit true to size.
- 12 bolts M10 × 1.25 with groovers.
- 8 spacers. You can use timing belt tensioner roller washers for the VAZ-2108.
When you have acquired all the necessary materials, it’s time to proceed directly to the replacement. The procedure is performed in several stages.
Installation of disc brakes
The location of the mechanism support can be either in front or behind the rear wheel axis. It will work in any case, but if you install it at the back, the efficiency becomes a little higher. Next, your task is to correctly connect the hub to the faceplate. Pay attention to defects, even the most minor ones. If there are deficiencies, carry out the joining work again.
Positive qualities of rear disc brakes
Yes, the main advantage is increased security. The braking distance is reduced, and it does not depend on the weather. The operation of the node is stable, the weather does not affect it in any way. For example, when it rains, drum brakes become ineffective and the braking distance increases. This is not observed when using disk drives.
Overheating is not a problem for disk structures. For example, when braking at high speeds, the fluid in the system heats up due to high friction force. The drum and pads can heat up almost red hot – up to 600 degrees. As a result, the pedal fails and braking efficiency deteriorates significantly. You'll never feel that way with disc brakes. Their device is simple and reliable, so you don’t have to worry about safety.
Dismantling
To install disc brakes back, the first step is to remove the old drum mechanisms. For this:
- Remove the wheel rim, loosen the tension on the handbrake cable and move the rear pads together;
- Unscrew the two guide pins with a 12mm wrench;
- Use a hammer to carefully knock down the brake drum, after cleaning its seat with a wire brush and WD40;
- Strike carefully, gradually around the entire circumference. If it does not give in, constantly turn the drum and hit it with a rubber hammer;
- Using a screwdriver, pry up the spring that tightens the pads and remove it;
- Next, the small guide springs are removed. They press the pads against the boot;
- Grasp the bottom of the shoe and lift it up, resting its top against the brake cylinder;
- Remove the spacer bar, remove the shoe from the cylinder and remove the shoe tension spring;
- Remove the handbrake lever from the cable;
- Remove the second block;
- Unscrew the bolts securing the hub to the beam. Be careful not to cut off the edges;
- Remove the brake pipe with a split wrench. Having torn it off, unscrew it completely and bend it slightly to the side;
- Close the tube with the cap from the brake cylinder bleeder fitting to seal the hole;
- You have reached the point of no return. The hub is now held only by the seat of the beam;
- You need to hit the element as accurately and forcefully as possible. Hit the support disk from the inside. First from below, then from above and so on alternately;
- Don't be afraid to ruin the support because you won't need it;
- When the hub separates from the beam, begin striking with less force;
- Tap the hub completely.
Upon completion of this stage, be sure to carefully check the integrity of all elements, so that after replacing the drums on the BDT, you do not have to disassemble the structure again for the purpose of additional repair of individual components of the brake system.
Installation of disc brakes
- Decide on the location of the caliper - behind or in front of the axle. This does not affect the effective operation of the brakes.
- Let's take the installation route at the rear of the axle. The picture turns out to be more symmetrical, plus indirectly the weight of the braking devices will contribute to better braking.
- Join the faceplate and hub into a single mechanism.
- Make sure that all technological holes line up perfectly.
- If there are any misalignments, correct them by simply tapping with a hammer.
- Make sure that the alignment was carried out efficiently and correctly.
- Adjust the beam angles. If this is not done, the calipers may rest against them, which is not good. This can be done with a hammer, flattening the corners. An alternative option is to use a grinder.
- The processing of a particular angle depends on which rear disc brake placement option you chose at the first stage.
- Whether to install a grower or not, the decision is yours. It is not recommended to place it under the upper left hub mounting bolt. If this is done, the bolt head will have to be cut out with a grinder. This will cause the brake caliper bracket to push against the bolt. So option two - grinder or refusal of the grower. We advise you to choose the second option.
- Place the rear brake disc ground to the required diameter onto the hub.
- Install the bracket onto the faceplate.
- A spacer is placed between them at the connection points. With their help, the necessary gaps are determined and fixed in the “caliper-caliper-brake disc” scheme.
- Sometimes the spacer is a different size. In this situation, you should select specifically for the VAZ 2114.
- The tightening process when connecting the faceplate and bracket is performed with an applied force of 3-4 Nm.
- Place the pads and screw the hoses back to the caliper.
- Next, the line for sealing the brake pipes and hoses must be closed.
- Under no circumstances should you do the opposite.
- Seal the brake line system.
- Check the tightness of the brake system by increasing the pressure by pressing the brake pedal.20. If there are no leaks, proceed to replacing the rear disc brakes on the second wheel.
- Upon completion of work, be sure to diagonally bleed the brake system.
Bleeding the brakes
After all the work has been carried out, it is necessary to perform bleeding - getting rid of air in the system. This is essential to improve operational efficiency. And once you’ve started upgrading, don’t forget to change all the components that have been serving for a long time. Replace hoses, front pads, VAZ-2114 vacuum brake booster, master cylinder. As for the fluid, it should be changed approximately every two years. Briefly, the pumping procedure looks like this:
- Pour liquid into the expansion tank.
- Bleed the right rear caliper.
- Check the fluid level and add if necessary.
- Bleed the left rear caliper.
- Repeat step 3.
- Bleed the right front caliper.
- Follow step 3.
- Bleed the front left caliper last.
Here's how to bleed the VAZ 2114 brakes correctly, the essence of the procedure is to go from the farthest to the nearest caliper (relative to the main brake cylinder).
Dismantling
Before installing disc brakes, you need to dismantle the old rear brake mechanisms of the VAZ 2114.
- Remove the wheel;
- Remove the brake drum;
- Remove the pads;
- Remove the hub from the wheel, having first unscrewed the brake pipe.
You should prepare for the fact that dismantling will not be easy. Not only do the brakes have the unpleasant tendency to stick during operation, but the bolts are also “welded” by corrosion. Therefore, it is advisable to treat the nuts and bolts themselves with a special agent (for example WD 40) so as not to tear off their edges.
It is important to plug the removed pipe with something so that brake fluid does not leak out and air is not sucked into the system. After that, knock down the hub. This works best if you attach a board or lath to the back of the support disk and hit it with a hammer, moving the blows: one from below, the other from above. This will prevent you from causing serious damage to the disk.
Need a handbrake?
But some motorists cannot do without a handbrake. And the new VAZ-2114, the price of which at one time was close to 300 thousand, does not have a handbrake, and this is not very convenient. In cities, parking lots are simply impossible without it. And if an autostart system is installed, then you simply cannot do without a handbrake - it is not recommended to set it to speed.
What is needed to install this mechanism? First of all, this is the handbrake itself, but not a cable one, but with a hydraulic cylinder. As a rule, they are universal, and new Chinese mechanisms cost from 1,500 rubles and more. And the rear disc brakes on the VAZ 2114 will be equipped with a handbrake system.
The installation procedure is extremely simple - put it in place of the old one, fasten it with bolts, connect it to the hydraulic system, namely to the part that controls the calipers on the rear axle. That's all, from now on you will have a handbrake that will work perfectly in any conditions. Neither overheating, nor frost, nor torrential rain is scary. And even in cold weather you can use the handbrake.
