Adjusting Brake Pressure Rod 1
86 Models Onward (without stop on brake-pedal arm)
Note:
It is only necessary to adjust the brake pressure rod if:
- the brake booster is replaced
- brake pressure rod adapter has been removed.
Adjusting
1.Adjust length of brake pressure rod by turning adapter or pressure rod. Length a must be 158 + 2 mm measured from the bearing face of the brake booster on the body to the center of the adapter pivot pin.
Note:
If the car has manual transmission and the brake pedal is more than 8 mm lower than the clutch pedal, correct position of brake pedal by turning pressure rod.
- the pressure rod or the adapter has been turned away from its original position.
The brake-pedal arm does not have a stop. The arm is in its initial position when brake unit (brake booster + brake master cylinder) is in its released position. Since the brake pedal is unsupported in its initial position when the brake pressure rod is correctly adjusted, the permanently set clearances in the brake booster are assured. When the brakes have been bled and with the engine switched off, a pressure-rod play of approx. 10 mm can be felt at the brake-pedal plate when the pedal is depressed by hand.
2.Tighten locknut.
3.Check setting of stoplamp switch (page 46 - 10a).
