Wilwood Small Ford Rear Parking and Service Brake Conversion, Red Dynapro Calipers, Plain 11-Inch Iron Rotors, 2.66-Inch Offset

Plain iron rotors and red low-profile service calipers give this rear conversion its compact friction assembly. The electric parking system uses additional calipers with motor housings, and its installation must preserve connector space around the Small Ford axle. 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.

Technical Details

• Manufacturer part number: 140-16153-R; supplied as one rear axle brake kit.
• Rotor dimensions: 11.00 in; 279.4 mm outside diameter; 0.81 in; 20.57 mm thick.
• Rear axle interface: Small Ford housing flange; 2.66 in; 67.56 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.
• Hydraulic installation: Hydraulic lines and fittings are separate and must be selected for the vehicle; master cylinder not included; brake booster not included.
• Caliper finish and port: Red Powder Coat; hydraulic inlet 1/8-27 NPT.
• Supplied service pads: BP-10 compound; verify suitability for the intended operating conditions.
• Mechanical contents: Separate wheel hubs are not included; mounting hardware supplied; spindles not included.
• 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.
• 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.
• Parking-brake package: Two separate electric parking calipers, control unit, switch with pigtail and universal wiring harness included; vehicle electrical connections require installation.

Fitment & Compatibility

This kit is selected for Small Ford geometry at 2.66 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.

Parking actuation is electric through a supplied controller, switch with pigtail, universal harness and two motor-driven calipers. The installer must provide suitable vehicle power/ground and ignition/accessory connections and check lead routing to DS1353. These additional calipers are for parking hold, not an emergency stop function.

PMB Performance has more than 20 years of parts experience and can help assess the documented brake configuration. Provide the vehicle details together with clear mounting-area photographs and measurements.

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