Wilwood Black Dynapro-LP Rear Brake Kit with Electric Parking Brake, Small Ford 2.50-Inch Axle Offset, Plain 11-Inch Rotors

This black Dynapro-LP rear conversion uses plain 11-inch rotor/hat assemblies at the 2.50-inch Small Ford axle offset. Separate electrically actuated calipers provide parking hold without requiring mechanical cables to the service calipers. Wilwood Engineering has its base in Camarillo, California and was founded by Bill Wood in 1977. The company’s work covers disc brake systems and components for specialized vehicles, street-performance applications and motorsport. Calipers, brake rotors, master cylinders, valves, fittings and brake lines must be chosen with the rest of the braking system in mind.

Technical Details

• Manufacturer part number: 140-16149; supplied as one rear axle brake kit.
• Supplied service pads: BP-10 compound; verify suitability for the intended operating conditions.
• 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.
• 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.
• Hydraulic service calipers: Forged Dynapro Low Profile; 4 pistons per caliper; Forged Aluminium body; lug mounting; Stainless pistons.
• Minimum nominal wheel diameter: 14 in; 355.6 mm; full spoke/barrel clearance must be checked using the installation drawing.
• Rotor material and surface: Iron; vented; Plain Face; surface finish Plain.
• Rear axle interface: Small Ford housing flange; 2.50 in; 63.5 mm axle offset. Measure the installed assembly.
• Parking-brake package: Two separate electric parking calipers, control unit, switch with pigtail and universal wiring harness included; vehicle electrical connections require installation.
• Mechanical contents: Separate wheel hubs are not included; mounting hardware supplied; spindles not included.
• Caliper finish and port: Black Powder Coat; hydraulic inlet 1/8-27 NPT.

Fitment & Compatibility

Use only an axle that matches the documented Small Ford flange and 2.50-inch offset. Rear-end names can conceal different bearing flanges, so measure the installed parts. Check the rotor register, studs, axle retention and complete wheel outline rather than relying on the nominal 14-inch wheel size.

Use 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.

Two 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.

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.
