Product details

This plain-face Special-end assembly places red Dynalite calipers over vented iron discs. At the rear axle, this kit pairs red powder-coated 4-piston calipers and 12.19-inch plain-face rotors with the mounting hardware for Chevrolet 12-bolt Special, 3.15-inch fixed bearing. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications, with a range including calipers, rotors, master cylinders, valves, fittings and brake lines. Selecting the mounting and hydraulic components together is part of building the complete brake system.

Technical Details

  • Manufacturer part number: 140-7578-R.
  • Rotor dimensions: 12.19 in; 309.63 mm diameter x 0.81 in; 20.57 mm thick.
  • Rotor construction: Iron; vented; Plain Face friction surface.
  • Housing/flange arrangement: 12 Bolt Special.
  • Axle flange offset: 2.81 in; 71.37 mm.
  • Wheel-size guide: 15 in; 381 mm minimum nominal diameter; verify actual template clearance.
  • Calipers: 4 pistons; forged aluminum; stainless steel pistons.
  • Caliper attachment: lug mount; 1/8-27 NPT hydraulic inlet.
  • Caliper finish: Red Powder Coat.
  • Rotor/hat wheel-stud clearance patterns: 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.
  • Rotor/hat stud-hole clearance diameters: 0.52 in; 13.21 mm. These are hole sizes, not wheel-stud thread specifications.
  • The rotor/hat drilling does not change the vehicle hub or axle wheel bolt pattern.
  • Sold as one kit. Mounting hardware is included. Hubs are not included.
  • Brake pads are included; use the compound and installation instructions specified for this rotor package.
  • Spindles, master cylinder, brake booster and hydraulic brake lines are not included.

Package and installation requirements

  • The fixed-bearing Special-end assembly includes internal parking shoes beneath the one-piece rear drum/rotors. Parking operation remains separate from the four-piston hydraulic service calipers.
  • Hydraulic flexlines and parking cables must be purchased independently. Check whether the universal 330-9371 cable arrangement needs alterations to connect to the vehicle.

Fitment & Compatibility

This Chevrolet 12-bolt Special package is built around a 3.15-inch fixed axle bearing and a 2.81-inch axle offset. It is distinct from Wilwood’s OE C-clip-end conversion. Verify the fixed-bearing housing-end dimensions in DS445 before interpreting any of the vehicle applications below. A modified Camaro, Chevelle or other listed GM car may have several possible rear ends, regardless of its front spindle setup. In this package the rear rotor also contains the drum for the internal parking shoes, giving the mechanical parking system its own friction surface. Complete the installation plan with cable adaptation, hydraulic lines and a wheel-template check. If the axle bearing or retaining hardware cannot be identified, obtain that information before selecting the kit.

The listed applications below retain their equipment qualifiers. Check the matching row and each referenced note before selecting the kit.
