INSTALLATION OVERVIEW

Installation requires working with disc brake systems. Experienced installers should note:
- The steering arm or spindle must be modified by drilling, tapping holes, and removing the interfering “ears” to allow the calliper mounting bracket to fit properly.
- Use of high-temperature disc brake bearing grease is recommended when packing inner and outer bearing cones.
- OEM brake hoses will not work with these callipers; steel braided brake lines and proper adapters are advised.
- Follow the full assembly instructions for torque settings (30 ft-lb for calliper mounting bolts; 77 ft-lb for wheel stud installation, among others) and proper use of shims to ensure alignment.
- Always verify that the hub stud pattern matches your wheels before final assembly.

FITMENT AND COMPATIBILITY

This brake kit is designed for 1970–1978 Camaros with factory disc brake spindles. Confirm that your hub stud pattern is 5 x 4.50 or 5 x 4.75. Significant modifications to the steering arm or spindle may be required, so consulting a qualified machine shop is recommended before installation.
