Product details

This Big Ford Bronco rear package uses drilled-and-slotted rotors and black radial-mount calipers. Its 12.88-inch friction rings connect to hats surrounding the mechanical parking-brake assemblies. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.

Fitment & Compatibility

Check the measured flange-to-wheel-face offset against the specified 2.36 inches. Follow DS1018 for register centering, wheel clearance and the separately adapted parking-cable and hose connections.

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.
