Wilwood Black Rear Dynalite/EPB Conversion, 12.19-Inch Plain Iron Rotors, New-Style Big Ford Housing and 2.36-Inch Offset

Plain 12.19-inch iron rotor/hat assemblies and black four-piston Dynalite calipers provide the rear service brakes in this kit. The parking function uses its own electric calipers and control hardware, mounted to the new-style Big Ford axle flange. From its Camarillo, California base, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications, with individual parts matched to the complete braking arrangement.

Technical Details

• Manufacturer part number: 140-16130; supplied as one rear axle brake kit.
• Rotor material and surface: Iron; vented; Plain Face; surface finish Plain.
• Hydraulic service calipers: Forged Dynalite Internal; 4 pistons per caliper; Forged Aluminium body; lug mounting; Stainless pistons.
• Rear axle interface: Big Ford New Style housing flange; 2.36 in; 59.94 mm axle offset. Measure the installed assembly.
• Minimum nominal wheel diameter: 15 in; 381 mm; full spoke/barrel clearance must be checked using the installation drawing.
• Caliper finish and port: Black Powder Coat; hydraulic inlet 1/8-27 NPT.
• 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 installation: Hydraulic lines and fittings are separate and must be selected for the vehicle; master cylinder not included; brake booster not included.
• Rotor dimensions: 12.19 in; 309.63 mm outside diameter; 0.81 in; 20.57 mm thick.
• Mechanical contents: Separate wheel hubs are not included; mounting hardware supplied; spindles not included.
• Parking-brake package: Two separate electric parking calipers, control unit, switch with pigtail and universal wiring harness included; vehicle electrical connections require installation.
• Supplied service pads: BP-10 compound; verify suitability for the intended operating conditions.

Fitment & Compatibility

Use only an axle that matches the documented Big Ford New Style flange and 2.36-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 15-inch wheel size.

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.

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.

Our team at PMB Performance can help compare the existing brakes with this kit’s requirements. Drawing on over 20 years of parts experience, we ask for the vehicle year, axle identification and wheel-clearance details.

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