Installing front brake pads
Replace vibration dampers each time the pads are changed.
The vibration dampers have an adhesive protective film. The protective film must be removed before installation.
Replace warning contacts if the core of the wire is worn.
The warning contact can still be used if there are only scrape marks on the plastic part of the warning contact.
Remove some brake fluid from the brake fluid reservoir by suction if necessary.
1. Before installation of the brake pads, check the wear of the brake discs. For details of the minimum thickness of the brake discs, see Technical data/Brake wear limit.
2. If necessary, reset the brake pistons using the piston resetting fixture.
3. Fit new vibration dampers in the pistons. Remove protective film from the vibration dampers before installation.
4. Insert the brake pads.
5. Fit new expanding spring, new retainer pin and new retainer. These parts are available as a repair set and must be replaced each time the pads are changed.
6. Insert the warning contact wire and the warning contacts.
7. Press the brake pedal several times to position the brake pads on the brake discs.
8. Check and, if necessary, correct the brake fluid level.
Bedding in the brake pads
New brake pads require a bedding-in period of approx. 200 km. Only then do they achieve their best friction and wear coefficient. During this period, the brakes should be subjected to full stress when travelling at high speed only in emergencies.
