All models of cars considered in the real Management are equipped with hydraulic brake system with vacuum strengthening. On forward wheels disk brake mechanisms whereas mechanisms of back wheels can have both disk, and a drum-type design are always established.

All brake mechanisms are equipped with self-regulators. Thus compensation of wear of brake shoes of disk mechanisms (forward and back) is carried out automatically whereas, on drum-type brake mechanisms the special adjusting devices which activation occurs during braking, and also when raising the parking brake are established.

The dual design of the main brake cylinder (GTTs) equipped with two separate tanks allows to break a hydraulic path into two, operating independently from each other, a contour. The last means that in default one of the contours, the second continues to work as before, providing adequate braking of the car. Hydraulic contours have a diagonal arrangement. Refusal of any of contours, naturally, conducts to decrease in efficiency of braking and is accompanied by operation of a control lamp on an instrument guard when squeezing a pedal of a foot brake.

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. The tank fastens in the cylinder by means of plugs through passage and a cylindrical pin.

As it was already mentioned above, 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.

Pressure regulator

Assembly of the valve regulator fastens on a back partition of an impellent compartment, near GTTs and provides pressure restriction in a hydraulic actuator of brake mechanisms of back wheels, preventing their premature blocking at sharp braking. The valve does not interfere with increase in pressure in hydraulic contours of back brake mechanisms only until it will not reach some threshold value, further growth of pressure is limited.

The regulator is among not maintainable components and in case of failure is subject to replacement assembled.

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.

Parking brake

The control lever of the parking brake is located in salon of the car and influences a draft rod to which pair of driving cables (on one on each of brake mechanisms of back wheels is attached). When raising lever on the models equipped with drum-type back brake mechanisms, cables delay the executive levers attached to assemblies of brake boots in mechanisms of both back wheels. Thus boots get divorced in the parties, nestling on a working surface of drums. On models with disk brake mechanisms of back wheels levers are attached to actuation mechanisms of screw type in cases of supports. Levers influence pistons of supports, forcing blocks to nestle on brake disks.

Precautionary measures

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

a) For filling of brake system use only hydraulic liquid of the class DOT 3;
b) Frictional overlays of brake blocks/boots 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;
c) 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;
d) At the slightest signs of violation of serviceability of functioning of brake system operation of the car should be suspended!
