Parking Brake System: Adjustments

Special tool: 1158147 torque socket

Procedure

The parking brake is adjusted by:
- adjusting the brake shoes in one rear wheel first and then the other
- then making any fine adjustments via the parking brake lever if necessary.

Preparations [MA1]
- Tighten parking brake slightly (a few notches) and drive car not more than 400 meters (420 yds). This will clean the brake shoes and brake drums, which are integrated in the rear brake discs free of rust and deposits.
- Remove both rear wheels.

Adjusting brake shoes [MA2]

- Tighten parking brake if not already tightened.
- Turn brake disc until adjustment hole is centrally over the little adjusting bolt which sits between the brake shoes.
- Repeat MA2 with other rear wheel, then continue with MA3.
- Adjust brake shoes by turning adjusting bolt upwards until brake disc will not turn any more.
- Then adjust shoes slightly by turning adjusting bolt 4-6 notches in the other direction.
- Adjust brake shoes as per MA2 for the other rear wheel, then continue with MA3.

[MA3]
- Check if there is any play between cable and brake lever. If there is no play, go to MA6 and install wheel.
- If there is any play between cable and brake lever, adjust at parking brake lever as per MA4-MA5.

Adjustment at parking brake lever [MA4]

- Remove the rectangular cover panel under the armrest on the center console to access adjusting bolt by parking brake lever.

[MA5]

- Turn adjusting bolt so full braking effect is achieved between the second and the eighteenth hole.
- Check that wheel turns freely after adjustment when parking brake is off.

Installing wheels [MA6]

- Check that brake disc and rim contact surfaces are clean.
- Grease hub center rim guide with anti-rust agent 116 1038-3.
- Install wheel.

- Install bolts hand tight, then tighten them across to 110 Nm (80 ft.lb). If using a nut runner, use torque socket 115 8147.

NOTE: The crosswise tightening and torque settings are important to avoid any stresses arising in the brake disc.
