GENERAL INFORMATION

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

Forward brakes

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

Outer diameter of a brake disk
240 mm
Disk thickness:
  – nominal
12,65 mm
  – minimum admissible
11,3 mm
Maximum beats of a disk
0,15 mm
Diameter of the cylinder of a support
54,0 mm
Type of brake shoes
Girling D 600 FF
Sizes of blocks
38 x 111 mm
Thickness of slips (without basis plate):
  – nominal
12,5 mm
  – minimum admissible
about 1,5 mm

Back brakes

Back brakes drum are also equipped with the mechanism of automatic adjustment of a gap of blocks.

DRIVING SYSTEM

Main brake cylinder

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

Vacuum amplifier of brakes

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

Pressure regulator

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