Removal 1. Remove the securing spring (3) carefully so that it does not deform. See Fig. 49 . 2. Remove the protective caps (1) from the two locating pins (2). See Fig. 49 . 3. Remove the locating pins using a 7 mm hex socket. 4. Remove the brake caliper from the holder. 5. Remove the brake pads. See Fig. 50 .
Inspection
NOTE: If the dust boot is damaged, dirt may have penetrated the cylinder. The brake caliper must be rebuilt. Clean and check brake pad mating surfaces on the brake caliper. Check piston dust boot. Replace it if it is damaged. Check brake disc friction surfaces. If the brake disc displays signs of out-of-true, check its lateral run-out. See MEASURING LATERAL RUN-OUT under INSPECTION. Replace brake disc if it displays signs of heavy wear, variable thickness or similar. Measure brake disc for minimum thickness and check against specifications. See DISC BRAKE SPECIFICATIONS .
Installation
1. Press piston back into cylinder on brake caliper. Check that the dust cover is correctly positioned. 2. Install new brake pads. See Fig. 50 . 3. Install the brake caliper. See Fig. 50 . 4. Instal the rubber sleeves of the locating pins. Replace if necessary. 5. Lubricate the locating pins with grease. Insert the locating pins (2) into the rubber sleeves. See Fig. 49 . The pins should slide into the sleeves easily.
