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).

Is this a replacement for the GM 18002328 Caliper. I own a 1936 Chevrolet Master Deluxe Street Rod with a "Fat Man" 6" dropped straight axle, with Chevrolet Bolt on Spindles, GM 11" by 1" disc rotor, and the GM 18002328 angled brake line caliper. Is your caliper a direct replacement for this unit of mine? Can you help.

This caliper is the midsize GM from '69 to '77 and stems from the Chevelle, Monte Carlo, etc. We apologize but that GM part number does not cross over in our computer. The mount centers for the slide bolts on this caliper are 7 1/16” center to center and the fluid inlet is 7/16" - 20 thread. If these specs match your caliper then it should be a direct replacement.

What size bleeder screw do these calipers use? 3/8-24 or 7/16-20? Bought these calipers awhile back. When I look up GM mid size calipers 69-72 it says 3/8-24 but the size and threads are way to small. Have these been modified from the factory originals?

This is not what we would refer to as a Metric caliper but it will work fine for your application as long as you use brackets part number 91631913. This would be for a Mustang II or Pinto spindle.

Rotor number 91031035 is commonly used on the GM and other manufacturers stock rotors measuring 1-1.10 thick. To use on a 1 3/16” thick rotor would require taking the pads down the needed amount for clearance. Modifying the caliper itself would not be recommended.

A 1" master cylinder should work for your application. Slide bolts are ot included, part #8352300542 sold as each. We offer several different pads for this caliper. Part #9191563 is the most economical. We also offer US Brake, Wilwood and Hawk pads

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.
