The D8-4 caliper is a direct bolt-on replacement for the factory original calipers on all 1965-82 Corvette's. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put and end to the rust, bore pitting, and seal failures that plague the OE caliper design. D8-4 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. D8-4 calipers mount in the stock location over stock rotors, and use the original style OE D8 brake pads. Calipers can be used with any wheel that clears the OE calipers. The factory piston sizes were duplicated to maintain the original front to rear brake bias and use of the OE master cylinder. Kits contain DOT compliant stainless steel braided brake lines with BP-10 high friction pads.
