D8-4 front and rear calipers are a direct bolt-on replacement for the OE factory calipers on all 1965-82 Corvettes. Forged billet aluminum bodies, stainless steel pistons, and high temperature seals put an end to the rust, bore pitting, and seal failures that plague the original cast iron caliper design.
D8-4 calipers mount in the stock location over stock rotors and use the original type D8
brake pads. These calipers fit inside 1967 and later production steel rally wheels and
most of the later model alloy wheels. Original steel “JK” code wheels from 1965-66, and
some aftermarket alloy replica wheels, will requires a 3/16” or thicker wheel spacer for
clearance.
D8-4 calipers use the same overall piston volumes as the original calipers. Other than a
new flexline with an 1/8”-27 NPT end for the new aluminum caliper, no other changes
such as master cylinder output or front to rear bias adjustment are necessary.
