Rear Disc Brake Pads: 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 .
