The brake system on the VAZ 2114 provides for the presence of a hydraulic drive. The peculiarity of the brake system on this car is the diagonal location of the brake contours. In the conditions of failure of one of them, the other provides braking with optimal efficiency. An important element of the brake system is the brake fluid, from the state of which the braking efficiency directly depends. About this further in the article.

Purpose of brake fluid

The brake fluid is designed to transmit effort from the main brake cylinder to the wheeled. The task is, though narrow, but extremely responsible.

The brake system under no circumstances has the right to refuse. If the fluid in the hydraulic drive does not suit, it would seem, you should not pay attention to it. But its condition affects the stability of the brake system and braking efficiency. If, for example, poor engine oil or antifreeze only reduce the service life of the motor, then poor-quality brake fluid can lead to an accident. That is why it must maintain its properties for a long time, as well as not freeze and not boil at working conditions.

Brake hydraulic system

The hydraulic engine of the brake system includes a mass of various components that allow the brakes to be performed using a working fluid. The composition of the hydraulic line includes:

1. Metal pipelines of both contours.
2. A tank, which is designed for the brake fluid bay and is attached to the main brake cylinder.
3. Flexible brake hoses of the rear and front wheels.
4. The main brake cylinder located in the engine compartment.
5. Two-circuit pressure regulator.
6. Working brake cylinders of the rear and front wheels.
7. Sensor, which shows the level of brake fluid.
8. Vacuum amplifier.

Replacing the brake fluid VAZ 2114 when you need to change brake fluid according to plan

The brake system is one of the main car systems, which ensures the safety of passengers and the driver, so the car owner must systematically carry out a preventive inspection of all its components. According to the recommendations of technical specialists, changing the brake fluid on the VAZ 2114 follows every three years or no more than 45 thousand kilometers of the mileage.

Replacing the brake fluid VAZ 2114, when the brake fluid replacement is required when brake system malfunctions

During the operation of the vehicle in the brake system, malfunctions can systematically appear, which lead to the need to replace the brake fluid. Knowledge of malfunction data, as well as the reasons that lead to them can help the motorist avoid serious problems on the road, because in this case it can timely diagnose the refusal and take the necessary measures to eliminate it.

The brake system malfunction, due to which the brake fluid should be changed:

1. Bending with working brake cylinders, which lead to a significant loss of brake fluid.
2. The appearance of air traffic jams in flexible hoses and main pipelines, which occur due to the lack of tightness in the braking system units.
3. Running or torn flexible hoses on wheels. In this case, the brake hoses will be required. Also possible damage to metal pipelines. Usually due to the "chasing" appears leak. In both cases, the liquid flows very quickly from the brake system. Therefore, even at the slight symptoms of disorder in the brake system, you should first check the details.
4. Blowing or damage to the sealing rings in the wheeled cylinders or the main brake cylinder. This also leads to leaks.
   
5. Clogging of metal pipelines, although this is a rare phenomenon.
6. The leakage of the brake fluid through the pusher sealing rings of the rear wheel pressure regulator.
7. Violation of the tightness of one with brake contours. In this case, there is a partial failure of the brake pedal.
8. As a result of mechanical damage, RTC, GTC, Vacuumnik and other brake system components are possible. To eliminate damage damage replacement of the brake fluid - a prerequisite.

What brake fluid to choose, selection criteria

When purchasing brake fluid, you should pay attention to such parameters:

1. Boiling temperature. To reduce the likelihood of the appearance of a tube with steam bubbles, the brake fluid booming temperature must be high.
2. Good viscosity. It characterizes the ability to pump the brake fluid in the system.
3. Gigroscopicity, that is, the ability to absorb water.
4. The ability to lubricate internal surfaces.
5. Neutrality in relation to rubber elements of the brake system.
   
6. Oxidation resistance.
7. Corrosion protection ability.

For VAZ 2114, brake fluids are underway under the labeling of dot 3.

Tools, fixtures, consumables

1. Brake fluid (0.5) liter.
2. Screwdrivers and keys.
3. Transparent flexible hose.
4. Rag.
5. Capacity for drain.

Choosing a workplace

Change the brake fluid is necessary in a well-ventilated room, as the liquid is toxic.

Replacing brake fluid VAZ 2114, step-by-step instruction

1. Open the cover on the GTC tank and put it on a pre-prepared surface. The cover is connected to the float of the brake fluid sensor, on which there are remnants of the exhaust toxic fluid.
   
2. Next, you should unlock the pressure regulator of the rear brakes using a screwdriver that you want to insert between the plate and the piston.
3. We clean from the dirt and dust the exhaust air valve of the rear right brake and unscrew the rubber cap, which closes this valve.
4. On the fitting of this valve, we put a flexible hose, in advance inserted into a transparent container.
   
5. Press the brake pedal to the brake pedal four times up to the interval of 2 seconds. With the fifth of the press fix it in the squeezed position.
6. We unscrew the valve at least by half the turn. The pedal must fall as the brake fluid is drained. When the liquid stops flowing, close the air valve.
   
7. Top and lower the brake fluid follows the moment until pure liquid flows from the pipe.
8. After the rear right brake, it is necessary to do a similar event with the front left brake mechanism. Consequently, in one contour, the brake fluid will be completely replaced.
   
9. All work in the second circuit is performed in the same sequence. At the end of the work, be sure to close the valve with rubber caps. Do not forget to attach the missing brake fluid into the tank of the main brake cylinder.

Tips Pros: how much brake fluid need, how to prevent the appearance of air traffic jam, how to pump brakes

To replace the TK on the VAZ 2114, you will need about 0.5 liters of fluid. In the process of work, control the fluid level in the tank, constantly topping it, in order to avoid the appearance of an air traffic jam. To carry out this event, you will need an assistant, since it will be necessary to pump the system with braking pedals.
