Repair and car operation

Brake system

All models of cars considered in the real Management are equipped with hydraulic brake system with vacuum strengthening. On all wheels disk brake mechanisms are established.

All brake mechanisms are equipped with self-regulators. Thus compensation of wear of brake shoes of mechanisms is carried out automatically.

The hydraulic system consists of two independent contours, forward and back. In default one of the contours, the second continues to function, providing the car adequate braking. The special control lamp built in in an instrument guard notifies the driver on violation of serviceability of functioning of brake system, and also about excessive falling of level of brake liquid.

Main brake cylinder (GTTs)

GTTs is established on assembly of the servo-driver of the vacuum amplifier of the brakes, fixed on a back partition of an impellent compartment. From above on the cylinder the big tank of hydraulic liquid equipped with a plastic cover is located.

GTTs has the dual design providing functioning of two independent hydraulic contours. Pressure of liquid in each of contours is forced by the individual piston in the main cylinder.

Vacuum amplifier of brakes

The amplifier uses depression created in the inlet pipeline for increase of efficiency of functioning of a hydraulic actuator of brake system. The servo-driver of the vacuum amplifier is fixed on a back partition of an impellent compartment in the last.

System of anti-blocking of brakes (ABS)

ABS prevents premature blocking of wheels of the car at sharp braking (see. The section System of anti-blocking of brakes (ABS) - the general information and codes of malfunctions).

Parking brake

The hummock drive of the parking brake is brought to brake mechanisms of back wheels of the car. Driving cables are brought to executive levers of assemblies of brake boots.

Service

On termination of any of procedures of the service, connected with removal or dismantling any of components of brake system without fail check efficiency of functioning of brake system and having only made sure of full serviceability of its operation, start car operation. Trial runs should be made on a pure dry and equal paving.

Check efficiency of braking of a vehicle on various speeds of movement and various efforts of squeezing of a pedal of a foot brake. The car should be braked evenly, keeping thus course stability. Try not to allow premature blocking of the wheels, fraught loss of control over management.

Remember that to number of the factors affecting efficiency of braking of a vehicle, the condition and pressure of a rating of tires, level of loading of the car and correctness of geometry of a suspension bracket belong.

Precautionary measures

At service of components of brake system of cars it is necessary to observe some special precautionary measures:

1. For filling of brake system use only hydraulic liquid of the class DOT 3;
2. Frictional overlays of brake shoes can contain unhealthy asbestos. Try not to inhale a brake dust, do not blow off it the compressed air. To rubbing of components of brake mechanisms apply only special cleaning structures;
3. Watch observance of all demanded admissions and efforts of a tightening of fixture. At service of components use only the serviceable tool. At the slightest doubts address for the help to experts. Remember that serviceability of functioning of brakes is guarantee of traffic safety;
4. At the slightest signs of violation of serviceability of functioning of brake system operation of the car should be suspended!
