Wilwood Caliper-D8-4 Rear Black 1.38in Pistons 1.25in Disc

This is the Wilwood D8-4 rear brake caliper, finished in black, designed specifically as a direct bolt-on replacement for the original rear calipers on 1965 through 1982 Corvettes. If your factory cast iron calipers are showing signs of rust, bore pitting, or seal issues, this caliper offers a solid upgrade. It's built to address the common problems found in the original equipment.

Wilwood constructs these calipers with forged billet aluminum bodies, which are much more resistant to corrosion than cast iron. Inside, you'll find stainless steel pistons and high-temperature seals. These materials are chosen to prevent the bore pitting and seal failures that often plague the stock calipers, ensuring more reliable performance and a longer service life. The 1.38-inch pistons and 1.25-inch disc compatibility are designed to work with your existing brake system.
