13. Brake system


Arrangement of elements of brake system without ABS on the car

1–tube of the highway of a high pressure of brake system;
2–brake pedal;
3–main brake cylinder;
4–vacuum amplifier of brakes;
5–forward disk brake mechanism;
7–back drum-type brake mechanism;
8–working brake cylinder;
9–popolnitelny tank;
10-block of hydraulic management;
11-cable of the parking brake;
12-lever of the parking brake.

On cars the working brake system with a hydraulic drive is used.

The system works as follows:

      – the pedal of a brake is connected with the main brake cylinder;
      – when the pedal is pressed, liquid under pressure from the main brake cylinder on metal tubes and flexible hoses is transferred to lobbies and back brake mechanisms;
      – working brake cylinders represent hydraulic modulators which transform the pressure of liquid created in the main brake cylinder in moving of elements of the brake mechanism;
      – lobbies and back pistons of a support of a brake move and at the expense of a friction about brake disks and drums provide demanded delay of the car;
      – at an otpuskaniye of a pedal of a brake pressure in system decreases.

Brake shoes and pistons come back to a neutral or starting position and braking stops.

At reduction of level of brake liquid the sensor of level of liquid in the main brake cylinder includes a control lamp in combinations of devices. If the control lamp burns, first of all check that the parking brake is released, as the lamp indicates the lowered level of liquid and the tightened parking brake.
