Wilwood 140-11291-BK Details

Wilwood's D52 Front Caliper Kit is a direct bolt-on 2 piston replacement for the factory original single calipers on many 1968-96 GM Passenger Vehicles and Trucks. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put an end to the rust, bore pitting, and seal failures that plague the OE caliper design. D52 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. D52 calipers mount in the stock location over stock rotors, use the original style OE D52 brake pads and an OE 7/16-20 banjo bolt brake line mounting. Calipers can be used with most wheels that clear the OE calipers. The front calipers with 2.00" piston provide 6.28 square inches of piston area per caliper, in order to maintain the original front to rear brake bias and use of the OE master cylinder. Kits contain Wilwood's hardened slide pins and BP-10 high friction pads. Matching rear calipers are also available for custom installations. Vehicles 1978 & Up (with M10-1.5 banjo bolts) will require new brake lines available below.

NotesPlease see the application chart under the Charts & Guide tab above. Fits GM vehicles from 1968-96 that have factory D52 single piston calipers and 1 in. thick rotors. Will not fit later models using Metric D154 calipers. The caliper inlet port is threaded for use with a 7/16-20 banjo bolt or a line adapter using crush washers as a seal. The OE rubber lines can be used from any vehicle equipped with a 7/16-20 banjo. For later model vehicles that were originally equipped with metric connections, a new line kit will be required.
