Product details
Plain-face Wilwood rear rotors and red calipers convert the OE C-clip Chevy 12-bolt service brake. Confirm axle dimensions; parking brake is absent. Bill Wood established Wilwood Engineering in 1977. From its base in Camarillo, California, the company designs and manufactures disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines. Individual parts are matched to complete motorsport, street-performance or specialized installations.
Technical Details
- Manufacturer part number: 140-2112-R
- Rotating brake parts: Vented iron rotors measure 12.19 inches across by 0.81 inch thick, with plain face friction surfaces.
- Service calipers: The red powder coat calipers use forged aluminum bodies and 4 stainless pistons apiece.
- Attachment requirements: The caliper uses a lug mount and accepts the specified 1/8-27 NPT inlet fitting.
- Housing-end requirement: 12 Bolt; Offset requires confirmation: manufacturer product page and instruction cover disagree.
- Rotor/hat wheel-stud clearance pattern: 5 X 4.5 in; 5 X 4.75 in; 5 X 5 in (5 X 114.3 mm; 5 X 120.65 mm; 5 X 127 mm)
- Wheel fit: The nominal 15-inch wheel requirement is conditional on the actual spoke and barrel shape.
- Kit supply: mounting hardware
- Not included: master cylinder, booster, spindles, flexible brake lines, hubs
- Parking brake: No parking-brake mechanism supplied
Fitment & Compatibility
This version requires the OE C-clip axle configuration and excludes special housing ends and C-clip eliminators. Confirm the housing, bearing retention and measured offset rather than choosing by the modified-vehicle examples below. The current page states 2.91-inch offset and DS-121 states 2.81 inches; resolve that difference with Wilwood before purchase. Select flexlines separately and check the wheel drawing.
