Established in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems. Its master cylinders, calipers, brake rotors, lines, fittings and valves support motorsport, street-performance and specialized applications, with each component selected for its role in the complete brake system.

Fitment & Compatibility

Match the actual axle end and its 2.36-inch offset, not a presumed model-year axle. DS1015 supplies the register and flange checks; select hydraulic lines and cable hardware separately.

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.
