Product Details

DFC’s GEOSPEC rotor line is engineered to OE specifications using G3000/G11H18 cast iron and tight machining tolerances. The coated finish helps resist rust better than conventional paint or zinc-style coatings, while the non-directional surface promotes consistent pad contact. The 5000 Advanced ceramic pads are formulated for stable friction performance and reduced break-in effort, and the included hardware is designed to restore proper spring tension and caliper movement in the rear brake assembly. This part number 4512-63181 is a direct-fit rear brake service solution for 2010-2013 Mercedes-Benz S400, 2009-2012 Mercedes-Benz SL550, and 2010-2011 Mercedes-Benz S550 without Sport Package.

Common Brake Issues This Kit Can Address

• Rear brake noise, squeal, or vibration
• Uneven pad wear or reduced caliper hardware tension
