Q & A

What's in the Box

Rebuilt 1969-77 mid and full size caliper. 7/16"-20 inlet so you can use the readily available brake hoses and hardware from Pre-1978 GM midsize cars. IMCA approved.

No core charge required. Fits 1" thick rotor. 2.8" diameter pistons installed. It has 7-1/16" center to center mounting holes. The width between mounting tabs is 2-3/4".

Application

This caliper is a standard full size GM caliper used for years on many vehicles (1969-72 Chevelle, 73-77 A-Body, 1969-1981 Camaro, 1977 Caprice, S-10 pickups, etc). It will fit any bracket / spindle designed for the large GM calipers (7” mount width).

Depending on the spindle and rotor size it will not fit in most 14” wheels (nor in 15” drum brake wheels).

Wilwood 120-10937 D52 Dual Piston Floater Caliper, 2 Piston/1.04 Disc
(Part #83512010937)
                        The D52 caliper 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 and 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. Calipers can be used with most wheels that clear the OE calipers. The front calipers with 2.00 piston provide 6.28 cubic inches of piston area per caliper, to maintain the original front to rear brake bias and use of the OE master cylinder. D52 Calipers come hardened slide pins.
