Wilwood Plain 11-Inch Rear EPB Conversion, Red Dynapro Low-Profile Calipers for Big Ford 2.36-Inch Axle Flanges

Red Dynapro-LP calipers and plain 11-inch rotor assemblies keep the service-brake package compact in this rear conversion. The supplied EPB switch, harness and controller operate additional parking calipers around the same rotors. From its Camarillo, California base, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications, with individual parts matched to the complete braking arrangement.

Technical Details

• Manufacturer part number: 140-16141-R; supplied as one rear axle brake kit.
• Parking-brake package: Two separate electric parking calipers, control unit, switch with pigtail and universal wiring harness included; vehicle electrical connections require installation.
• Rear axle interface: Big Ford housing flange; 2.36 in; 59.94 mm axle offset. Measure the installed assembly.
• Minimum nominal wheel diameter: 14 in; 355.6 mm; full spoke/barrel clearance must be checked using the installation drawing.
• Supplied service pads: BP-10 compound; verify suitability for the intended operating conditions.
• Caliper finish and port: Red Powder Coat; hydraulic inlet 1/8-27 NPT.
• Rotor material and surface: Iron; vented; Plain Face; surface finish Plain.
• Hydraulic service calipers: Forged Dynapro Low Profile; 4 pistons per caliper; Forged Aluminium body; lug mounting; Stainless pistons.
• Hydraulic installation: Hydraulic lines and fittings are separate and must be selected for the vehicle; master cylinder not included; brake booster not included.
• Rotor dimensions: 11.00 in; 279.4 mm outside diameter; 0.81 in; 20.57 mm thick.
• Mechanical contents: Separate wheel hubs are not included; mounting hardware supplied; spindles not included.
• Cataloged rotor/hat mounting-hole pattern: 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm; 5 x 5 in; 5 x 127 mm bolt circle; cataloged stud-hole clearances 0.52 in; 13.21 mm. The existing hub or axle flange determines the vehicle wheel pattern and stud specification. These rotor/hat drillings do not convert that pattern.

Fitment & Compatibility

This kit is selected for Big Ford geometry at 2.36 inches of axle offset. Wheel-stud pattern and register dimensions must match the supplied rotors or hats, and the parking motors and harness connectors need clearance throughout suspension travel. Compare the intended 14-inch or larger wheel with the installation drawing.

Review the fitment table below after identifying the rear axle. Confirm housing-flange dimensions, retention hardware, offset, register and wheel pattern against the kit drawing. 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.

The supplied EPB switch and pigtail connect through a universal harness to the controller and separate parking-caliper motors. Vehicle-specific power, ground and ignition/accessory wiring still requires installation under DS1353. This static-hold system is independent of the service brakes and is not intended for emergency stopping.

With over 20 years of parts experience, PMB Performance can help check the brake arrangement before ordering. Send the vehicle year, axle photographs and relevant hub or suspension changes.

Review the Installation instructions, Technical bulletin, EPB mounting and wiring instructions before selecting hardware or checking wheel clearance.
