Wilwood GM D52 Dual Piston Calipers, Red - 140-11290-R SKU: 3024-RED
Wilwood GM D52 Dual Piston Calipers, Red - 140-11290-R
Product Overview:
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.

Asked by Gray Lange, April 30, 2022
Q: I'm looking to upgrade calipers and rotors on my 69 bronco. It went through a front disk brake conversion at some point and has an Adelco Moraine 5470 caliper. Will this replace that? What rotors would I need to replace those as well?
Answered by ☆ sales - May 3, 2022
A: Yes, these calipers should fit and replace you current GM conversion. The disc kits use stock 76-77 hub and rotor assemblies and bearings. We would use our part # 3004, though you may find something drilled or slotted elsewhere to look fancier and dissipate heat etc.
Asked by Mike, May 14, 2016
Q: Will these calipers work with a 15x10 wheel?
Answered by ☆ sales - May 16, 2016
A: They should. Depending on the wheel design. We have had one guy go this route, he had stock wheels and had to run a 1/4 spacer to clear the caliper.
