All models of cars considered in the present manual are equipped with the hydraulic brake system with vacuum strengthening. On forward wheels disk brake mechanisms whereas mechanisms of back wheels can have both a disk, and drum design are always installed.
All brake mechanisms are equipped with self-regulators. At the same time compensation of wear of brake shoes of disk mechanisms (forward and back) is carried out automatically whereas, special adjusting devices which activation happens during braking, and also at raising of the parking brake are installed on drum brake mechanisms.
The dual design of the main brake cylinder (MBC) equipped with two separate tanks allows to break a hydraulic path into two, acting independently from each other, a contour. The last means that in case of refusal one of contours, the second continues to work as before, providing adequate braking of the car. Hydraulic contours have a diagonal arrangement. The refusal of any of contours, naturally, leads to decrease in efficiency of braking and is followed by operation of a control lamp on an instrument guard when squeezing a pedal of a foot brake.
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. 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. Liquid pressure in each of contours is forced by the individual piston in the main cylinder.
Pressure regulatorAssembly of the valve regulator fastens on a back partition of a motive compartment, near GTTs and provides restriction of pressure 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 does not reach some threshold value, the 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 brakesThe 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.
Parking brakeThe control lever of the parking brake is located in interior of the car and influences a draft rod to which couple of driving cables are attached (on one on each of brake mechanisms of back wheels). At raising of the lever on the models equipped with drum back brake mechanisms, cables delay the executive levers attached to assemblies of brake boots in mechanisms of both back wheels. At the same time boots get divorced in the parties, nestling on the working surface of reels. 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 measuresAt service of components of the brake system of cars it is necessary to observe some special precautionary measures:
a) For gas station of the brake system use only hydraulic liquid of the class DOT 3;
b) Frictional overlays of brake blocks / boots may contain noxious to health asbestos. Try not to inhale brake dust, do not blow off it compressed air. Apply to rubbing of components of brake mechanisms only the special cleaning structures;
c) You monitor observance of all required admissions and efforts of tightening of fixture. At service of components use only the serviceable tool. At the slightest doubts ask for the help experts. Remember that serviceability of functioning of brakes is the key to traffic safety;
d) At the slightest signs of violation of serviceability of functioning of the brake system operation of the car has to be suspended!
