Wilwood Red Rear Superlite Disc and Electronic Parking Brake Kit, Small Ford Housing, Drilled 14-Inch Rotors and 2.66-Inch Offset

Red Superlite calipers work on drilled-and-slotted 14-inch rear rotor rings in this axle-specific conversion. Additional motorized red parking calipers and the supplied switch, harness and controller provide static hold without cable actuation. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. Wilwood designs and manufactures disc brake systems for motorsport, specialized vehicles and street-performance applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines must be selected in relation to the other components in the finished brake system.

Technical Details

• Manufacturer part number — 140-16156-DR; supplied as one rear axle brake kit.
• Rotor material and surface — Spec-37 Iron; vented; SRP Drilled & Slotted; surface finish Black Electro Coat.
• Supplied service pads — BP-10 compound; verify suitability for the intended operating conditions.
• Rotor dimensions — 14.00 in; 355.6 mm outside diameter; 1.10 in; 27.94 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 0.520 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.
• Minimum nominal wheel diameter — 18 in; 457.2 mm; full spoke/barrel clearance must be checked using the installation drawing.
• Caliper finish and port — Red Powder Coat; hydraulic inlet 1/8-27 NPT.
• 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 — Small Ford housing flange; 2.66 in; 67.56 mm axle offset. Measure the installed assembly.
• Mechanical contents — Separate wheel hubs are not included; mounting hardware supplied; spindles not included.
• Hydraulic service calipers — Forged Narrow Superlite 4R; 4 pistons per caliper; Forged Aluminium body; radial 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 mounting hats — Aluminum; Black E-Coat; hat offset 2.035 inches. This is a hat dimension, not the axle offset.

Fitment & Compatibility

Match the actual rear axle to the Small Ford diagram and 2.66-inch offset before disassembly. Verify the bearing arrangement, axle register and wheel-bolt pattern independently, including any changes made during a previous axle conversion. Use the full 18-inch minimum wheel envelope for both caliper positions.

Any vehicle application in the fitment table below depends on the installed axle interface. Compare flange and bearing geometry, axle offset, center register and wheel hardware with the specified assembly. 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 EPB is a parking-hold system, not an emergency stopping brake. It includes a separate left/right motor-driven caliper pair, control unit, switch with pigtail and universal wiring harness. Vehicle power, ground, ignition/accessory connections and protected cable routing must be installed to DS1353; it is not a plug-in factory-harness replacement.

Before selecting the conversion, PMB Performance can review the listed requirements with you. We have over 20 years of parts experience; include axle measurements and any wheel, hub or suspension changes.

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