Wilwood Red Rear Dynapro-LP Disc and EPB Package for Small Ford 2.50-Inch Axles, Plain 11-Inch Iron Rotors

The undrilled 11-inch rotor surface is paired with red Dynapro-LP service brakes in this rear kit. A dedicated electric parking system adds motor-driven calipers and control components, mounted on the matched 2.50-inch-offset 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: 140-16149-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.
• 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; 2.50 in; 63.5 mm axle offset. Measure the installed assembly.
• Mechanical contents: Separate wheel hubs are not included; mounting hardware supplied; spindles 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.
• Rotor material and surface: Iron; vented; Plain Face; surface finish Plain.
• Minimum nominal wheel diameter: 14 in; 355.6 mm; full spoke/barrel clearance must be checked using the installation drawing.
• 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.
• 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 Small Ford geometry at 2.50 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.

The fitment table below is subject to physical axle-interface confirmation. Check housing flange, bearing arrangement, offset, wheel-stud pattern and center register before ordering. 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.

With more than 20 years in parts, PMB Performance can help review the compatibility checks for this conversion. Include information about the axle, retained hubs and any changes from the original suspension.

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