Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a matched rear brake solution for drivers servicing GM passenger cars with rear disc brakes. The coated rotors are machined to tight tolerances, inspected for balance, and finished to support even pad contact. The brake pads are formulated for consistent friction, with post-curing and scorching steps that reduce initial break-in effort and help deliver stopping response from the first stop. This kit is a practical choice for rear brake replacement on the 2006-2010 Chevrolet Impala, 2008-2009 Buick Allure, 2008-2009 Buick LaCrosse, and 2006-2007 Chevrolet Monte Carlo. Part number 4502-45043 is also a useful reference when searching for a rear brake kit for these applications.
