Product details

GT-slotted rear rotors, red four-piston calipers and internal parking brakes form this Small Ford Bronco package. Its 14-inch friction rings use iron hats sized for the documented axle register and wheel pattern. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.

Fitment & Compatibility

Use DS1027 to check the actual housing end, not a presumed original axle. Confirm the 2.36-inch offset, wheel profile and separate hydraulic/cable requirements before assembly.

A maximum flange diameter of 6.61 inches and a 0.050-inch x 45-degree chamfer are specified for rotor clearance. The illustrated register is 2.88 inches; select the documented centering arrangement and match both axle offset and housing-end bolt pattern.

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.
