    Wilwood 140-11292-BK Details

    Wilwood's D52 Rear Caliper Kit offers a matching rear replacement option for our front D52 calipers. It is a direct bolt-on 2-piston replacement for the factory original single piston calipers used on many custom application rears. With the added benefit of smaller rear piston sizing (2.46 sq-inches of area) not normally available in OEM calipers, for correct front and rear bias. 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. Kits contain Wilwood's hardened slide pins and BP-10 high friction pads. Matching rear calipers are also available for custom installations.

    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 1.25 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.
