Repair and car operation

Brake system

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

All brake mechanisms are equipped by self-regulators. Thus indemnification of deterioration brake колодок 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 infringement of serviceability of functioning of brake system, and also about excessive falling of level of a brake liquid.

The main brake cylinder (ГТЦ)

ГТЦ it is established on assemblage 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 a hydraulic liquid equipped with a plastic cover is located.

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

The vacuum amplifier of brakes

The amplifier uses depression created in the inlet pipeline for increase of efficiency of functioning of a hydrodrive 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 antiblocking of brakes (ABS)

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

Lay brake

The trosovyj drive of a lay brake is brought to brake mechanisms of back wheels of the car. Privodnye cables are brought to executive levers of assemblages 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 only having made sure of full serviceability of its operation, start car operation. Trial runs should be made on a pure dry and equal road covering.

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 in regular intervals, keeping thus course stability. Try not to suppose the premature blocking of wheels fraught with loss of the 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 tyres, level of loading of the car and correctness of geometry of a suspension bracket concern.

Safety measures

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

1. For refuelling of brake system use only a hydraulic liquid of class DOT 3;
2. Frictional overlays brake колодок can contain unhealthy asbestos. Try not to inhale a brake dust, do not blow off its 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 traffic safety pledge;
4. At the slightest signs of infringement of serviceability of functioning of brake system car operation should be suspended!
