PRODUCT DESCRIPTION
Product details
D8-4 Front Brake Caliper
D8-4 front calipers are a direct bolt-on replacement for the factory original front calipers on all 1965-1982 Corvettes. Forged aluminum bodies, stainless steel pistons, and high-temperature seals provide an end to the corrosion, bore wear, and seal failure that plagues the original cast iron caliper design.
D8-4 calipers mount in the original location over the stock rotors and use the stock D8 type brake pads. These calipers will clear 1967 and later rally wheels and most aftermarket alloy wheels. Original 1965-66 “JK” code steel wheels, and some aftermarket alloy wheel replicas, require a 3/16” or thicker wheel spacer for proper clearance.
D8-4 calipers use the same total piston volume as the OE calipers. Other than a new flex line with a 1/8”-27 NPT end for the new aluminum caliper, no other changes, such as master cylinder output or front to rear brake bias adjustments, are required.Rotor Dimensions
