6.1.1. Design of the brake system

By pressing a pedal of a brake in the main cylinder pressure of brake fluid which puts pistons in action increases (two ahead and four behind).

Main cylinder tandem. Brake highways are connected to the main cylinder, they form two independent contours. One contour ensures functioning forward right and back left brake mechanisms, another – the forward left and back right brake mechanism.

Pressure limiter depending on loading (LSPV) or the limiter of pressure (P-valve) is switched on in brake contours between the main cylinder and the back brake mechanism for cars without anti-blocking system of brakes.

In this brake system of a brake of forward wheels – disk, brakes of back wheels – drum.

The parking brake system has the mechanical drive. The parking brake system has the drive only on brake mechanisms of back wheels by means of a cable and mechanical communications. The same brake shoes are used for parking and for the working brake system.

Brake contour of the Suzuki Liana car: A – for the car without anti-blocking system of brakes; In – for the car with anti-blocking system of brakes; 1 – amplifier of brakes; 2 – main cylinder; 3 – secondary party; 4 – primary party; 5 – connection; 6 – hydraulic block of anti-blocking system brakes / module of management; 7 – P (proportional) valve or connection; 8 – LSPV (Pressure limiter depending on loading) if is available; A – forward

NOTE In the figure 6.1 the car with the left arrangement of steering is shown.

Design of the hose / pipeline of the forward brake mechanism of cars with anti-blocking system of brakes: A – for cars with the left arrangement of steering; T – top; F – forward party; R – right side; Z – type of Z; 1 – from the first camera of the main brake cylinder to the hydraulic block of anti-blocking system of brakes; 2 – from the second camera of the main brake cylinder to the hydraulic block of anti-blocking system of brakes; 3 – from the hydraulic block of anti-blocking system of brakes to the left forward brake mechanism; 4 – from the hydraulic block of anti-blocking system of brakes to the right forward brake mechanism; 5 – hydraulic block of anti-blocking system of brakes; 6 – main cylinder; 7 – hose of the forward brake mechanism; 8 – connection of anti-blocking system of brakes; 9 – from the hydraulic block of anti-blocking system of brakes before connection of anti-blocking system of brakes; 10 – from the hydraulic block of anti-blocking system of brakes before connection of anti-blocking system of brakes; 11 – from connection of anti-blocking system of brakes before back connection; 12 – from connection of anti-blocking system of brakes before back connection
