Product details

Red four-piston calipers sit outside the SRP rotor faces in this Bronco-style Small Ford rear kit. The separate internal parking-brake mechanism requires suitable vehicle cables rather than hydraulic pressure to hold the car. Since its founding by Bill Wood in 1977, Wilwood Engineering has focused on disc brake system design and manufacturing. Based in Camarillo, California, it offers calipers, rotors, brake lines, master cylinders, fittings and valves for motorsport, street-performance and specialized installations. Choose components to satisfy the requirements of the entire braking system.

Fitment & Compatibility

Use DS1015 to verify the Small Ford flange and measured 2.36-inch axle offset. Confirm the axle register and the SRP rotor's listed wheel-pattern provisions before finalizing the hose and cable connections.

The installation drawing specifies a 2.88-inch axle register and the corresponding centering-adapter arrangement. Check the housing pattern and axle offset, then confirm the flange fits within the 6.61-inch diameter limit with its 0.050-inch x 45-degree chamfer.

The installation reference identifies Small Ford Bronco rear applications with 2700-lb axle/10-inch drums for 1966–1973 and 2900-lb axle/10-inch drums for 1974–1975. The measured2.36-inch offset and actual housing flange still govern selection.

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.
