Fitment & Compatibility
Match the actual axle-end dimensions to DS1027 and verify its 5 x 5.50-inch pattern. Check the complete radial-caliper envelope before adapting the separate parking-brake cables.
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.
