Wilwood Red Superlite Rear Brakes with Electric Parking Control, Drilled 12.88-Inch Rotors for Small Ford 2.66-Inch Axles

Red Superlite service calipers and drilled two-piece rotors form the rear friction package for this 2.66-inch-offset Small Ford conversion. A second red caliper at each wheel is motor driven for parking, rather than being connected to the hydraulic service circuit. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. The range includes calipers, rotors, master cylinders, valves, fittings and brake lines, chosen to suit the mounting and hydraulic requirements of the complete system.

Technical Details

• Manufacturer part number — 140-16155-DR; supplied as one rear axle brake kit.
• Rotor mounting hats — Aluminum; Black E-Coat; hat offset 2.035 inches. This is a hat dimension, not the axle offset.
• Caliper finish and port — Red Powder Coat; hydraulic inlet 1/8-27 NPT.
• Rotor dimensions — 12.88 in; 327.15 mm outside diameter; 1.10 in; 27.94 mm thick.
• 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.
• Minimum nominal wheel diameter — 17 in; 431.8 mm; full spoke/barrel clearance must be checked using the installation drawing.
• Rotor material and surface — Spec-37 Iron; vented; SRP Drilled & Slotted; surface finish Black Electro Coat.
• Rear axle interface — Small Ford housing flange; 2.66 in; 67.56 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.
• 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.
• Supplied service pads — BP-10 compound; verify suitability for the intended operating conditions.

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 17-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.

A separate electric caliper at each rear wheel performs the parking function; it does not replace the hydraulic service circuit. Supplied EPB equipment includes the controller, switch/pigtail and wiring harness. Install the vehicle power, ground and accessory connections using DS1353. Use the system only for parking hold, not 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.
