WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2004 Volvo S80, 2004 Volvo S60, 2003 Volvo S80, 2003 Volvo S60, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.

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 .
