Product details
Red calipers and patterned discs identify this parking-brake-equipped Camaro/Firebird kit. For 1993–1997 Chevrolet Camaro / Pontiac Firebird, Wilwood specifies red powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors in this rear package. Bill Wood founded 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. This kit should be matched to the hydraulic and mechanical requirements of the complete vehicle.
Package and installation requirements
- The one-piece iron drum/rotors incorporate the parking-brake drums; the internal shoes provide a mechanical parking brake independently of the four-piston service calipers.
- Parking-brake cables and hydraulic brake lines are separate. Wilwood references universal cable kit 330-9371; installation can require cable or vehicle modifications.
- Not for Special housing ends or C-clip eliminators.
- Wilwood specifies hat drilling for 7/16-inch, 1/2-inch and 12 mm studs. The listed front/rear flexline reference is 220-6746; confirm routing and length for the installed system.
Fitment & Compatibility
The rear axle must retain the OE C-clip arrangement used on the listed 1993–1997 Camaro and Firebird applications. Special housing ends and C-clip eliminator conversions need a different mounting assessment. This kit is based on the 2.75-inch axle offset shown in DS428. Wilwood specifies hat drilling for 7/16-inch, 1/2-inch and 12 mm studs, but the actual axle still determines the wheel bolt pattern. The supplied internal parking shoes require a correctly routed and adjusted cable connection. Check the existing parking hardware when planning the installation instead of assuming it attaches unchanged. The 12.19-inch rear rotor and caliper also need template clearance inside the chosen wheel, including the spokes; the original wheel diameter alone is not a clearance guarantee.
Review the fitment table and numbered notes below together; a matching model name alone does not establish the installation.
