Keep your disc brake calipers sliding freely and sealed against road grit with the Dorman - First Stop Disc Brake Caliper Bushing / Hardware Kit (HW5568). The bushings and boots ride on the caliper's guide pins, letting the caliper float on the rotor while keeping dust and moisture out of the pin bores. This kit is designed to match the original hardware needed to service the front and rear disc brake calipers on a wide range of Audi and BMW models, including the 1984-1988 Audi 5000, 1996-1999 Audi A4, 1995-2004 Audi A6, 2001-2005 BMW 325I, and 2001-2006 BMW 330CI.
