Brake system

1 — the brake pipeline
2 — a brake pedal
3 — the main brake cylinder
4 — the brake amplifier
5 — the distributor of brake pressure
6 — a forward disk brake
7 — a brake support

8 — a back disk brake
9 — a brake support
10 — a back drum-type brake
11 — the wheel brake cylinder
12 — the hand brake
13 — a drive of the hand brake
14 — the lever of the hand brake

The brake system consists of the main brake cylinder, the brake amplifier, disk brakes of forward wheels and drum-type brakes of back wheels. At some models disk brakes are established as well on back wheels. The hydraulic brake system is divided into two contours, operating diagonalno. One brake contour influences on right forward/left back wheels, other contour influences on forward left/back right wheels. At the expense of it at failure of one of contours, for example, because of a leakage the car can be stopped by means of other contour. By pressing of a pedal of a brake in the dual main brake cylinder pressure for both contours is created. The distributor of brake pressure switched on after the main cylinder provides that at sharp braking back wheels are not blocked. The compensatory tank with brake liquid is in an impellent compartment over the main brake cylinder and provides with brake liquid all system. The brake amplifier on the petrol engine accumulates a part of low pressure made by the engine. If necessary force of pressing of a pedal increases at the expense of vacuum. As on the diesel engine of vacuum of absorption does not suffice, low pressure for the brake amplifier creates the vacuum pump fixed behind on the generator. Disk brakes are equipped with floating supports. In a floating support only one piston, for pressing of both brake shoes to a disk is used.

The hand brake influences back wheels through a hummock drive. Blocks of disk and drum-type brakes are regulated automatically; the main adjustment is necessary only after repair at which the brake system understood. Depending on the MAZDA 323 model with 10/89g. вып. it can be equipped with anti-blocking system (ABS). The works described here belong to all MAZDA 323 options, regardless of, whether they have ABS or not.

At pro-cleaning of brake system the brake dust rises. This dust can harm to health. Therefore at pro-cleaning of brake system to watch, that this dust was not inhaled.

Brake shoes are defined for each model at plant. Therefore it is recommended to use only firm blocks recommended by MAZDA firm.

After installation of new brake shoes, they should be earned extra. On the first 200 km it is not necessary to make complete braking needlessly.

Works on brake system demand purity and accuracy of performance. In the absence of necessary experience, work on brake system should be made in a special workshop.
