Cleaning and inspection
Clean the following components and inspect them for damage prior to assembly:
Brake caliper anchor bracket
- Carefully remove any corrosion from the brake pad contact faces using a wire brush
Brake caliper
§ Check the dust protection boot of the piston for damage
§ Clean guide bolts and check for damage
§ After cleaning, apply a thin coat of silicone-based grease to the sliding surfaces
ABS sensor
- Check for correct seating and for signs of damage
Axle journal
- The axle journal should be free of burr, flat and rust-free
- After cleaning, coat the axle journal with a little calibrating oil and spread evenly using a clean cloth
Only clean using brake cleaner, a brush and a lint-free cloth. It is essential to avoid mechanical damage to the guide surfaces.
Preparations
Preparing for installation:
- Compare new and old brake discs.
- Check the ABS impulse ring (magnetic coder) installed on the brake disc prior to installation
- Clean brake disc with brake cleaner if necessary
- Check level of brake fluid in expansion tank
- If at the MAX. mark, unscrew cover from brake fluid tank and extract a little fluid
Installation
Installing the brake disc:
- Position the brake disc with integrated wheel bearing centrally on the axle journal and slide on
- Screw on hub nut and tighten to specified tightening torque
- Fit hub cap
- Install brake caliper anchor bracket
-
- Tighten fixing screws to specified torque
- Push brake piston right back using reset tool
-
- At the same time, turn the piston to the right
- Please note the brake fluid level in the expansion tank
- Insert the piston-side inner brake pad
- When doing so, make sure that all three brackets of the retaining spring are inserted into the piston groove
