Notes

Note:  When the caliper bracket is affixed to the spindle properly so that the bracket is square to the spindle and brake rotor face for proper caliper alignment and installation, the welded roid that features female threads in the caliper bracket will be offset inboard or towards the centerline of the vehicle in relation to the centerline of the caliper bracket plate.

Wilwood 120-10937 D52 Dual Piston Floater Caliper, 2 Piston/1.04 Disc
                        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.

Wilwood 290-0632 570 Brake Fluid, 12 oz Bottle
                        

Wilwood's specially formulated Hi-Temp 570° Racing Brake Fluid has a minimum 570 degree dry boiling point to withstand the severe heat requirements of automotive racing. Hi-Temp 570's low viscosity allows easy bleeding of your brake system, eliminating aeration of the brake fluid caused by foaming due to excessive pumping of the pedal. 

This high temp brake fluid comes in a convenient 12 ounce container hermetically sealed to guarantee against unwanted absorption of moisture which can drastically lower the fluids boiling point (fluid from larger containers tends to become contaminated with moisture, lowering its boiling point and making it unsuitable for racing applications). 

  • Dry Boiling Point:  573° F
  • Wet Boiling Point:  313° F
