Wilwood Plain 11-Inch Rear Brake Kit with Red Dynapro-LP Calipers and EPB Controls, Chevy 12-Bolt C-Clip Housing, 2.75-Inch Offset

Plain 11-inch rotor assemblies and red Dynapro-LP calipers provide hydraulic service braking in this Chevy 12-bolt conversion. Independent red electric parking units supply holding force, with the axle’s C-clip retention and measured 2.75-inch offset determining suitability. Wilwood Engineering began in 1977 under founder Bill Wood and is based in Camarillo, California. It designs and manufactures disc braking equipment for motorsport, specialized applications and street-performance vehicles. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form part of the range and must match the requirements of the complete system.

Technical Details

• Manufacturer part number: 140-16163-R; supplied as one rear axle brake kit.
• Minimum nominal wheel diameter: 14 in; 355.6 mm; full spoke/barrel clearance must be checked using the installation drawing.
• Parking-brake package: Two separate electric parking calipers, control unit, switch with pigtail and universal wiring harness included; vehicle electrical connections require installation.
• Hydraulic installation: Hydraulic lines and fittings are separate and must be selected for the vehicle; master cylinder not included; brake booster not included.
• Rear axle interface: 12 Bolt housing flange; 2.75 in; 69.85 mm axle offset. Measure the installed assembly.
• Hydraulic service calipers: Forged Dynapro Low Profile; 4 pistons per caliper; Forged Aluminium body; lug mounting; Stainless pistons.
• 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.
• Rotor material and surface: Iron; vented; Plain Face; surface finish Plain.
• Caliper finish and port: Red Powder Coat; hydraulic inlet 1/8-27 NPT.
• Rotor dimensions: 11.00 in; 279.4 mm outside diameter; 0.81 in; 20.57 mm thick.
• Supplied service pads: BP-10 compound; verify suitability for the intended operating conditions.
• Mechanical contents: Separate wheel hubs are not included; mounting hardware supplied; spindles not included.

Fitment & Compatibility

This kit is selected for 12 Bolt geometry at 2.75 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. Confirm C-clip axle retention and end play; a C-clip eliminator or different housing flange requires its own fit assessment.

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 Chevelle, 442, Beaumont, Camaro and Apollo vehicles, establish rear-axle fit independently of the front spindle configuration. Confirm the housing flange, axle retention and offset on the installed rear assembly.

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.

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.
