Product Details
D52® Series Dual Piston Floater Brake Caliper (120-10936-RD) by Wilwood®. The D52 caliper is a direct bolt-on 2 piston replacement for the factory original single calipers on many 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 rear calipers with 1.25” piston provide 2.46 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..
The D52 caliper was designed using computer generated 3D modeling and FEA stress analysis technology. They have been configured to mount in the stock location with OE type slide-pins in position over the original rotor usingstandard OE type brake pads. This caliper design features a stress-flow forged billet aluminum body that provides asubstantial weight savings over the original cast iron caliper, without any of the rust and corrosion issues that arecommon to cast iron parts. Stress flow forging realigns the internal grain structure of the metal within the contour of thecaliper body to create a caliper that is superior in strength to any cast or machined from block billet caliper design. Theresimply is no better way to build an aluminum caliper with more strength or less weight.
These highly efficient two-piston calipers generate big brake clamping force from a pair of machined stainless steelpistons. Stainless pistons are used to resist corrosion and retard heat transfer from the pads into the caliper body. The dual piston design concentrates the clamping force over the entire length of the pad to improve pad loading whileminimizing uneven wear and backing plate deflection over all single piston caliper designs. High temperature, squarefaced bore seals are used to provide controlled piston retraction and reliable performance from the wider sealing face.This combination of components is a proven performer with long service life and a history of reliable performance in anytype of driving environment, including extreme sustained high temperature racing applications. The caliper slide pinholes are fitted with dampening rings to minimize noise from vibration. The caliper is also fitted with bleed screws onboth ends to facilitate mounting in any left hand or right hand, front leading mount, or rear trailing mount locations.
