Product details

This red-caliper rear conversion uses SRP rotor faces around an internal parking brake. It requires the Big Ford Bronco housing-end geometry, not the smaller-bearing bracket pattern. From Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and their components. Founded by Bill Wood in 1977, it serves street-performance, motorsport and specialized applications with master cylinders, calipers, brake rotors, valves, fittings and brake lines. All components must suit the requirements of the complete system.

Fitment & Compatibility

Measure the axle-end offset and register using DS1017. Confirm the actual stud pattern and wheel clearance, and choose the parking cables and hydraulic lines for the vehicle's installation.

Measure the axle flange and register before mounting the brake: the flange must be no larger than 6.61 inches, with a 0.050-inch chamfer at 45 degrees. Use the instructions for the 2.88-inch register and its centering adapters as applicable, alongside the required offset and housing pattern.

The installation reference identifies Big Ford Bronco rear applications with 3300-lb axle/11-inch drums for 1966–1975 and the listed 1976–1977 configurations. Verify the actual flange,2.36-inch offset and axle register.

Hydraulic hoses/fittings and parking-brake cables, adapters and cable hardware are not included. Choose a compatible cable arrangement for the internal parking brake; universal cable systems may require vehicle or cable modifications.
