10. Brake system

10.1. Technical characteristics

The working brake system is put in action гидравлически. In system the vacuum amplifier of brakes is used. The brake system consists of two contours. Forward brakes disk, and back – drum-type. The manual brake is put in action mechanically and puts in action back brakes.

Forward brakes

Forward brakes – disk. In them full disks and floating a support with one piston are used.

External diameter of a brake disk
240 mm
Thickness of a disk:
  – The nominal
12,65 mm
  – Is minimum admissible
11,3 mm
Maximum disk palpation
0,15 mm
Diameter of the cylinder of a support
54,0 mm
Type brake колодок
Girling D 600 FF
The sizes колодок
38 x 111 mm
Thickness of overlays (without a basis plate):
  – The nominal
12,5 mm
  – Is minimum admissible
About 1,5 mm

Back brakes

Back brakes drum-type also are equipped by the mechanism of automatic adjustment of a backlash колодок.

Thickness of overlays:
  – The nominal:
     • колодка the synchronous
4,75 mm
     • колодка the asynchronous
3,25 mm
  – Is minimum admissible:
1 mm
Type колодок
N/F 360 IF.FF


The main brake cylinder

In a cavity of the main cylinder consistently two pistons are located, each of which operates the contour.

The vacuum amplifier of brakes

The vacuum amplifier of brakes influences the main brake cylinder and contains one diaphragm.

Pressure regulator

The pressure regulator is established on the pipeline of back brakes and limit force of braking of back wheels.

The main brake cylinder
Bendix or Ate
Diameter of pistons
22,0 – 22,2 mm
The vacuum amplifier of brakes
The operating diameter
227 mm
