NOTE:
- When work has been completed, actuate brake pedal several times to ensure that brake pads make firm contact with brake disks.
- When installing new brake linings on the rear axle and simultaneously replacing the brake linings on the front axle, check the brake-fluid level and top up to the "MAX" marking necessary

Procedure
- Remove wheels.





- Lift out retaining spring (1).
Right side: Disconnect plug connection for brake lining wear indicator.





- Remove plastic plug (1).





- Unfasten guide screws (2) with special tool 34 1 040 and pull brake caliper backwards to remove.
- Installation:
Only clean guide screws; do not grease.
Check threads.

Inner brake lining is located with its spring in the piston.

CAUTION:
- Mark any worn brake linings.
- In the event of one-sided brake lining wear, do not change brake linings round.
- New brake linings should only be installed if the brake disk thickness is greater than or equal to minimum thickness (MIN TH), refer to Dimensions. Mechanical Specifications
- Note residual lining thickness of brake linings, refer to Dimensions. Mechanical Specifications

- Clean brake linings.
- Do not grease brake lining back plate.





- Check dust sleeve (1) for damage and replace if necessary.
- Clean contact surfaces (2) of brake piston and coat with a thin layer of anti-squeak compound.
