All models of cars considered in the present manual are equipped with the hydraulic brake system with vacuum strengthening. On all wheels disk brake mechanisms are installed.
All brake mechanisms are equipped with self-regulators. At the same time compensation of wear of brake shoes of mechanisms is carried out automatically.
The hydraulic system consists of two independent contours, forward and back. In case of refusal one of contours, the second continues to function, providing to the car adequate braking. The special control lamp which is built in in an instrument guard notifies the driver on violation of serviceability of functioning of the brake system, and also on excessive falling of level of brake fluid.
Main Brake Cylinder (MBC)
GTTs is established on the assembly of the servo-driver of the vacuum amplifier of brakes fixed on a back partition of a motive 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. Liquid pressure in each of contours is forced by the individual piston in the main cylinder.
Vacuum amplifier of brakes
The amplifier uses the depression created in the inlet pipeline for increase in efficiency of functioning of a hydraulic actuator of the brake system. The servo-driver of the vacuum amplifier is fixed on a back partition of a motive 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).
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.
Upon completion of any of procedures of service connected with removal or dismantling any of components of the brake system without fail check efficiency of functioning of the brake system and having only made sure of full serviceability of its operation, start operation of the car. Trial runs should be made on a pure dry and equal paving.
Check efficiency of braking of the vehicle at various speeds of the movement and various efforts of squeezing of a pedal of a foot brake. The car has to be stopped evenly, keeping at the same time course stability. Try not to allow premature blocking of wheels, fraught loss of control over management.
Remember that the state and pressure of a rating of tires, level of loading of the car and correctness of geometry of a suspension bracket belong to number of the factors making impact on efficiency of braking of the vehicle.
At service of components of the brake system of cars it is necessary to observe some special precautionary measures:
