GENERAL INFORMATION

FORWARD BRAKES

Brake shoes

Since August, 1988 (a code of date of production of "JE") in the Ford Sierra cars with diesel engines material of brake shoes is changed. Besides, thickness of a flange of a disk of a brake is increased from 7 to 8,5 mm, and thickness of a flange of a rotary fist from 8 to 9 mm.

Installation of disks of forward brakes of new type in rotary fists of old type

Surely it is necessary to check length of hairpins of fastening of a wheel. If it makes 36,5 mm, then they should be replaced surely with hairpins 40 mm long (nuts of fastening of a wheel have to be established on the corresponding length of a carving).

BRAKE DISK

Check of beats (measurement by the indicator of hour type)

Maximum beats of a rotary fist: 0,08 mm.

Maximum beats of a disk: 0,08 mm.

DRIVING SYSTEM OF BRAKES

Vacuum pump

Since 1987 the Ford Sierra cars with diesel engines are equipped with the vacuum pump of new type installed on a former arm. It cannot be rejected at adjustment of a tension of a driving belt.

Installation of a driving belt of the vacuum pump

PERFORMANCE ORDER
1. To weaken bolts of fastening of the vacuum pump to an arm and the arm bracket bolts fixing it to the engine.
2. To take a bolt of fastening from an arm and to move the vacuum pump.
3. To take off a driving belt of the pump.
4. To establish a new belt. To insert the taken bolt and to tighten all bolts of fastening of the vacuum pump.

Brake hoses

In holding time of the brake system it is necessary to check a condition of brake hoses (on all length).


Prevention

When raising the car from below suspension bracket elements excessively fall that causes wrest of elastic brake hoses from fastenings. Brake hoses should be checked and established carefully them on places of fastening.


ANTI-BLOCKING SYSTEM

Since February, 1988 (a code of date of production of "JR") the wire of mass of the pump of the ABS system is connected directly to the negative plug of the accumulator.

Other information concerning a technical characteristic, adjustment and repair of the brake system is provided in section 10.
