Replacing brake fluid on a VAZ 2114 - which one to choose, when to change it

The brake system is one of the most important in a car, since the safety of everyone in the cabin depends on its flawless operation. Sooner or later, every car enthusiast is faced with the need to pay attention to the brakes, and this is where the question arises of how much brake fluid is needed to replace or top up.

When should you change your brake fluid?

Many drivers believe that the TJ is poured into the system for the entire service life of the car and does not require replacement. However, even high-quality fluids begin to lose their properties over time, which can lead to brake failure at an unexpected moment. The main reason for the loss of properties of TJ is the ingress of moisture into it. Water in the system carries the risk of freezing, which will cause pipe damage and brake failure.

Since the replacement procedure is simple, it is recommended to change the fluid every 30-35 thousand kilometers. Often during this period the liquid loses its properties. The high water content in the fluid means that in hot weather during prolonged braking there is a risk of the fuel fluid boiling. In general, replacing brake fluid on a VAZ 2114 with your own hands does not take much time, so you should not neglect this procedure.

Adding fluid or replacing it completely

If the car has covered 50-60 thousand kilometers or has been in use for 2-3 years, experts recommend completely updating the brake fluid, since the old one has already absorbed a lot of water and has partially lost its properties. Topping up the fluid may be necessary if the car has been idle for a long time or, conversely, is used too intensively and travels, for example, 80-100 thousand kilometers per year.

Much depends on the type of fluid, as well as driving style. Thus, an aggressive, sporty style may require more frequent brake replacement. As for its specifications, everything depends on the manufacturer’s recommendations. Thus, one of the most popular brands of Dot 4 is advised to be updated every 50-60 thousand mileage or after repair of the braking system.

Which brake fluid should I choose?

The abundance of technical fluids for a car makes the procedure for choosing a technical fluid quite complicated. Marketing gimmicks and an excessive amount of information on a bottle of “braking fluid” should not be the only reason to buy. You should choose a TJ based on the following characteristics:

• The viscosity of the liquid must remain the same at any temperature;
• The presence of boric acid in the composition, which neutralizes moisture;
• Ability to maintain effectiveness at high temperatures.

Several types of fuel fluid are classified, but most often drivers use DOT 4 class fluid. The basis of liquid from this class is compounds of esters with boric acid. This composition helps to preserve properties at any time of the year.

We recommend considering the following TJ options for purchase:

1. "Dzerzhinsk brake fluid". Designed for use in hydraulic drives of brake systems and clutches of domestic and imported cars. Compatible with all domestic and imported glycol-based fluids. It has a boiling point of more than 2300C. The price of a 900 gram bottle is 160 rubles.
2. TJ from . The modified composition of the Bosch version is sold at a price of 400 rubles per liter. Endowed with improved characteristics against the formation of steam bubbles at high temperatures and increased intervals between replacements (up to 2-3 years).

As you can see, the price for this technical fluid is acceptable, so you should not save and look for the cheapest option. A low-quality vehicle can fail at the wrong moment. Also, when purchasing, check the product for counterfeit. It is recommended to purchase “brake guards” at trusted points of sale.

Recommendations for servicing the brake circuit of the VAZ 2114

• Conduct scheduled technical inspections of the vehicle in a timely manner;
• When purchasing, carefully check the catalog numbers with the data specified in the instruction manual;
• Use the services of certified points of sale.

Service station experts recommend purchasing DOT-4 on semi-synthetic and synthetic bases. It is “synthetics” that meets many modern requirements and quality standards.

Mineral-based lubricants are not always effective for high speed conditions and systematic loads. If you have any difficulties choosing a technical vehicle for a VAZ 2114, contact service station specialists and auto store managers for help.

Car malfunctions that lead to replacing the TG with a VAZ 2114

The hydraulic actuator that provides brake sensing (software) means many different parts that allow the hydraulic fluid to be used to activate the brakes. How to remove the dashboard and instrument cluster from VAZ VAZ 2112) How to remove 2114 VAZ 2115 VAZ 21099. It includes:

• tank attached to the GTZ, not intended for filling the TZ;
• iron pipelines of both circuits;
• flexible front brake hoses, not rear wheels;
• Installed under the hood of the GTZ;
• working brake cylinders of the front, not the rear wheels;
• dual-circuit pressure regulator;
• a sensor showing what level the TJ is at;
• a vacuum booster, the purpose of which is to create operating water pressure in the pipelines of the circuits to ensure effective operation of the braking systems in motion during braking.

A vehicle is one of the main systems that ensures the safety of the driver, and not the passengers of the car, so constant preventive inspection of all parts of the car is inevitable for the car owner.

Replacing brake fluid on a VAZ 2114, according to the recommendations of technical experts, is carried out every three years or no more than 45 thousand kilometers.

When using a vehicle, its brake system, especially the hydraulic drive, sometimes develops problems that lead to the replacement of the TJ. The main purpose of the tachometer on the VAZ 21099 carburetor is how to connect a tachometer. Knowing these defects, rather than the circumstances of this top list, helps the driver avoid serious problems on the road, since he or she can detect the problem until they take action to fix it.

There is a malfunction in the vehicle, so a replacement TJ needs to be created:

1. Leakage from the service brake cylinders results in a significant loss of TA.
2. Formation of air accumulation in main pipelines from hard hoses resulting from leaks in vehicle components.
3. Hurry differently, break the flexible hoses while moving, then you need to replace the brake hoses on the VAZ 2114. How to disassemble the doors of the VAZ 2114 and remove the linings? Damage to iron pipelines is also possible due to "chase". In any case, the fluid quickly flows out of the car, so at the slightest sign of trouble in the car. these parts must be checked first.
4. Damage to another O-ring seal in the GTZ, in other words, the wheel cylinders. The steps when replacing brake fluid on a VAZ 2114 are the same as when bleeding the brakes, only in this case the old brake fluid is not removed from the system, and not from the air. This also leads to leakage.
5. TJ leakage through the rear wheel pushrod ring seal.
6. For you, a violation of the density of the textbook from the brake chains. How can you install a turbine to install a turbine on a VAZ; on the VAZ 2107 2106 2101 engine. This is a partial malfunction of the brake pedal.
7. Quite often, but iron pipelines are clogged there.

Changing the brake fluid itself

Addressing this problem, Technical Environment, its presenter Gennady Emelkin will say that without the help of others it will change.

Selection of brake fluid and procedure for replacing it on a VAZ 2114

For vehicle operation with the highest efficiency, it is important for motorists to choose the right working fluid to drive the hydraulic brake. Modern TJs, such as Rosa, but not its variants, contain polyglycols that make up 93 to 98 percent of the total. Today we have a VAZ 2108, 2109 car service. It was decided to change this. Therefore, in people like him. Replacing thresholds on a VAZ 2114 Removing rust on a car door How to remove rust. Rest. various additives necessary for adhesion to snowflakes during the oxidation of fuel oil to prevent corrosion of the iron parts of the car.

When purchasing a TJ, you need to pay attention to the following characteristics:

• The boiling point, like that of oil, should be high to reduce the likelihood of steam bubbles forming;
• excellent viscosity, which characterizes the ability to pump water into the system;
• ability to absorb water, naturally hygroscopic;
• ability to lubricate internal surfaces;
• neutrality towards rubber parts, allowing (braking) braking to be taken into account;
• Oxidation resistance is not the ability to prevent corrosion.

In the TJ class for the VAZ 2114, DOT 3 is marked.

How to change the brake

fluid for VAZ 2114. For the correct actions, you need to carefully study the operation of the car.

Before you start, you need to prepare the appropriate tool, not materials:

1. TG in the amount of 0.5 l;
2. keys are not screwdrivers;
3. transparent flexible hose;
4. container for draining waste fuel oil;
5. a cloth for wiping surfaces, especially plastic ones, that do not get dirty, since the liquid is toxic and not aggressive to these surfaces.

To replace the TJ, you need to lure a helper because it requires bleeding, which allows the (software) monitoring of the brake pedal.

• On the GTZ side, open the lid and do not place it on the prepared surface. The cover is combined with the TJ level float; he has the remains of the old poisonous TJ.
• Unlock the brake disc using a screwdriver that must not be inserted between the piston plate.
• Do not remove dirt from the right rear brake release valve. Do not unscrew the rubber cap covering the mythical valve.
• Place a flexible hose, previously inserted into a transparent container, over the connection of this valve.
• At two-second intervals, press the pedal four times in the full program, 5th press, lock it in the pressed position.
• Unscrew the valve more than half a turn. How to improve headlights on a VAZ 2114. During a rainstorm, the TJ pedal should fail. How to bleed the brakes on a VAZ 2114 (video) etc. When the liquid does not leak, close the air valve immediately.
• During these stages, it is necessary to monitor the water level in the tank, constantly adding water to prevent air build-up. There is no need to add until the liquid has flowed out, until completely new, flawless liquid flows out of the tube.

The problem of brake fluid leakage has affected many car enthusiasts. If brake fluid leaks on a VAZ 2114 and other cars, you must first identify “weak spots” - where the fluid can go.

What is needed for replacement?

Before starting replacement work, you should stock up on a set of tools, rags and a new brake guard. It should be understood that it contains active chemical elements that can cause burns if they come into contact with the skin. Having clean water on hand is also a good idea. Replacement Tool Set:

• Keys for "8" and "10";
• Containers for collecting waste “slurry”;
• The hose is 15-20 centimeters long.

Gloves should be used during operation. You will also need a partner to pump the system. Carrying out this procedure without an assistant is possible, but requires special equipment.

According to statistics from the European Motorists' Community (ECA) for 2015 - 2022, 23% of accidents are caused by a faulty brake system.

Owners often underestimate the importance of brake circuit prevention (hereinafter referred to as TC). Late replacement of friction linings, late fluid renewal and monitoring of fluid levels are the most common factors.

The process of independently servicing the fuel tank and replacing the fluid is not at all difficult, but it requires attentiveness on the part of the technician. Violation of the regulations is unacceptable.

Brake fluid replacement process

If you decide to change the brake fluid on your VAZ 2114 yourself, you should prepare the necessary tools in advance and invite a friend. It is difficult to perform such a procedure alone, so to save time you should find an assistant.

The step-by-step process of replacing DOT 4 in the “four” looks like this:

1. Stop the car on an overpass or pit.
2. Remove the cap from the TJ tank and move to the rear right wheel.
3. Remove the cap from the bleeder fitting.

4. Take an empty container and fill it with some DOT 4.
5. Next, put the hose on the fitting and lower its second end to the bottom of the container with the “brake housing”.
6. Now you should press the brake pedal about 7-9 times. For this you will need an assistant.

7. Unscrew the fitting a few turns and, while pressing the pedal, drain the used DOT-4.
8. When there are a couple of centimeters of brake fluid left in the reservoir, screw the fitting back on and release the pedal.
9. Fill the tank to the maximum level and continue the procedure until pure DOT-4 comes out of the tube.
10. Carry out this procedure on the remaining wheels.

Important! When carrying out work, the following order should be observed: rear right wheel, front left, rear left and front right.

In order to prevent air from entering the system, do not allow the liquid level in the tank to drop to a minimum. Periodically check the brake fluid reservoir for leaks or damage. Damaged brake hoses that allow air into the system can also be a reason for changing the fluid. Despite the fact that the durability of hoses is high, there is always a risk of mechanical damage due to friction if installed incorrectly.

Keep in mind that the “four” system includes about 800 milliliters of DOT-4, so to carry out all pumping procedures you will need at least one liter of TJ. You should not mix different types of fuel fluid with each other. If the system previously used DOT-3, then the new class of “slurry” should be filled only after the old waste has been completely drained.

Causes of brake fluid leakage in VAZ 2114

You can understand that the amount of brake fluid is insufficient by looking into the reservoir. Also, sometimes, when approaching a car, you can see stains of leaked chemicals under it. And when driving, the system begins to work incorrectly: the brake pedal is felt, and the quality of braking deteriorates. In addition, an exclamation mark indicator may light up on the dashboard and will not go out when the car is released from the handbrake. All this often indicates a leak. Its main reasons may be:

1. Crack in the tank. This problem can be easily detected by looking under the hood. A cracked tank should be replaced immediately.
2. Hoses. When a leak appears, cracks and other defects, as well as traces of liquid, can be seen on them. To the touch, such hoses become inelastic and rigid. If such defects are detected, worn parts must be replaced.

3. Brake cylinders. Their malfunction is a little more difficult to detect than all other causes of leakage due to the “four” drum brakes. Therefore, to check the brake cylinders, you will have to remove the drums. If defects are detected, it is recommended to replace the cylinder assembly. This part for this car is inexpensive. Therefore, there is no point in disassembling it and replacing individual elements.
4. Master brake cylinder. Most often, its sealing cuffs wear out. It is not difficult to notice their wear upon inspection. In this case, the elements change. You can also see pockets of corrosion or mechanical damage on the cylinder. In this case, the entire part is replaced.

If a leak appears from the system, you cannot use the car until the problem is eliminated. It is very dangerous! You can identify and fix problems yourself. But, if self-diagnosis or repairs cause difficulties, you need to urgently contact a service station.

Brake system hydraulic drive device

The hydraulic brake system includes a variety of components that allow the brakes to be actuated using hydraulic fluid. The hydraulic drive includes:

1. Metal pipelines of both circuits.
2. A reservoir, which is designed to fill the brake fluid and is mounted on the main brake cylinder.
3. Flexible brake hoses for rear and front wheels.
4. The master brake cylinder located in the engine compartment.
5. Dual-circuit pressure regulator.
6. Brake cylinders for rear and front wheels.
7. A sensor that shows the brake fluid level.
8. Vacuum booster.

Are modern brake fluids interchangeable?

The liquid manufacturer usually indicates on the label what other liquids its product can be mixed with. But the trouble is that the consumer, as a rule, has no idea what is in his tank. No one has tested mixed liquids, so we cannot recommend such an operation. And you certainly shouldn’t add liquids with low boiling points to a modern car. In general, a complete fluid change is always preferable and safer.
