{"product_id":"wilwood-140-16134-dr","title":"Wilwood Red Dynalite and EPB Rear Caliper Kit, Drilled 12.19-Inch Rotors, Big Ford Bronco Housing with 2.00-Inch Offset","description":"\u003cp\u003eRed hydraulic and electric calipers share the drilled 12.19-inch rotor at each rear wheel in this conversion. The short 2.00-inch axle offset is essential: matching the Bronco flange name without checking that dimension is insufficient. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering manufactures and designs disc brake systems and components. The range serves motorsport, street-performance and specialized applications with calipers, brake rotors, master cylinders, valves, fittings and brake lines. Matching individual components requires considering the full brake assembly.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number — 140-16134-DR; supplied as one rear axle brake kit.\u003c\/li\u003e\n\u003cli\u003eMinimum nominal wheel diameter — 15 in; 381 mm; full spoke\/barrel clearance must be checked using the installation drawing.\u003c\/li\u003e\n\u003cli\u003eSupplied service pads — BP-10 compound; verify suitability for the intended operating conditions.\u003c\/li\u003e\n\u003cli\u003eCataloged rotor\/hat mounting-hole pattern — 5 x 4.5 in; 5 x 114.3 mm; 5 x 5.5 in; 5 x 139.7 mm bolt circle; cataloged stud-hole clearances 0.56 in; 14.22 mm; 0.64 in; 16.26 mm.

Verify the bearing arrangement, axle register and wheel-bolt pattern independently, including any changes made during a previous axle conversion. Use the full 15-inch minimum wheel envelope for both caliper positions. DS1411 identifies the 1966–1977 Ford Bronco 11 x 1.75-inch drum axle; choose this kit’s specific offset, not the alternative shown in the same manual.\u003c\/p\u003e\u003cp\u003eUse the fitment table below together with a measured axle check. A model name alone does not establish conversion compatibility; compare the flange, axle offset, register and chosen wheel pattern. For a 1990 Lincoln Town Car, identify the actual axle and confirm the specified interface; do not select this conversion from model and year alone.\u003c\/p\u003e\u003cp\u003eTwo dedicated motorized calipers provide parking hold separately from the hydraulic service calipers. The kit supplies their switch with pigtail, control unit and universal wiring harness. DS1353 covers the required 12V vehicle connections and component placement. The EPB is not an emergency stopping brake.\u003c\/p\u003e\u003cp\u003eWith more than 20 years in parts, PMB Performance can help review the compatibility checks for this conversion.
