Product details

Plain-face rotors and red HM7 calipers distinguish this Honda rear-drum conversion. The one-piece 9.37 x 0.39-inch discs retain the original hub arrangement, and the calipers combine hydraulic service braking with mechanical parking-brake actuation. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications.

Fitment & Compatibility

Converts the original rear-drum applications listed for Honda Civic, CRX and Civic del Sol to rear discs with a cable-operated parking brake. DS-1696 identifies the 1988–2004 Civic rear-drum installation; use the table for the specific model, trim, transmission and ABS restrictions rather than assuming every model in that period fits. Verify the hub/upright geometry and 2.71-inch offset. The existing hubs are retained. Includes 16-inch braided flexlines; parking cables are separate and must suit the HM7 lever and cable-end arrangement. Nominal minimum wheel diameter: 14 in; 355.6 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.

  • Friction faces: Plain Face
  • Rotor/hat wheel-stud clearance patterns: 4 x 3.94 in
