3.1.4.10.1. Technical characteristics
THE GENERAL DATA

Since November, 1988 all versions can be equipped by antiblocking system.

The working brake with antiblocking system is put in action гидравлически by the two-planimetric main brake cylinder (type a tandem) and in addition hydraulic auxiliary device.

Hydraulic a contour of lobbies of the right and left brakes are divided and cope the main brake cylinder. Back brakes (in system "Y") cope the hydraulic auxiliary device.

The manual brake is put in action mechanically (cable), характеризируется with automatic elimination of a backlash and operates on mechanisms of back brakes.

Forward brakes

Forward brakes disk. In them ventilated disks, and also floating a support with one piston are used.

Support

Mark and type: Ford 2L 232. Diameter of the piston: 60 mm.

Disk

External diameter: 240 mm.

Thickness:

 – The nominal: 24мм;
 – The nominal admissible: 22 mm.

Maximum disk palpation: 0,15 mm.

Brake колодки

Mark and type колодок: Ferodo 343 25 FF. A nominal thickness: 18 mm.

Nominal admissible thickness: it is defined by flute deleting on a surface brake колодки.

Back brakes

Back brakes disk. In them full disks, and also floating a support with one piston are established.

Support

Mark and type: Ford L2 9024. Diameter of the piston: 43 mm.

Disk

External diameter: 252,7 mm.

Thickness:

 – The nominal: 10,1 mm;
 – The nominal admissible: 8,9 mm.

Maximum disk palpation: 0,15 mm.

Brake колодки

Mark and type колодок: DON 8106/1. A nominal thickness: 13,5 mm.

Nominal admissible thickness: it is defined by flute deleting on a surface brake колодки.

Drive system

The system putting in action a working brake, is hydraulic, contains the two-planimetric main brake cylinder and the hydraulic auxiliary device, and also antiblocking system.

Mark: ABS Teves. The electronic actuation device: Teves.

Resistance of the gauge of speed of rotation of a wheel: 0,8–1,4 Ohm.

Control pressure: 4–9 МПа.

Brake liquid

Quantity: 1,4 дм3.

Type: brake liquid Ford SAM 6C 9103 A.

Periodicity of replacement: each 60 000 km or time in two years.
