Product details

Red Dynapro calipers work with plain vented 12.19-inch rotors in this Big Ford Bronco rear package. The rotor contains a separately actuated parking-brake mechanism; the wheel pattern is the specified 5 x 5.50-inch arrangement. 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

Confirm the flange dimensions and 2.36-inch offset on the actual axle. DS1017 provides the register, clearance and assembly requirements; cables and flexible brake plumbing are not supplied.

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.
