Calipers:
ALL NEW 1969-77 mid and full size GM style caliper is a standard full size GM caliper used for years on many vehicles (1969-72 Chevelle, 73-77 A-Body, 1969-1981 Camaro, 1977 Caprice, S-10 pickups, etc). It will fit any bracket / spindle designed for the large GM calipers (7” mount width).

- Has 7-1/16" center to center mounting holes
- The width between mounting tabs is 2-3/4"
- Depending on the spindle and rotor size it will not fit in most 14” wheels (nor in 15” drum brake wheels)

- IMCA Approved
- 7/16"-20 Inlet
- 10mm-1.5 bleeder screw

Brake Rotors:
Every rotor is cast from premium grade, long grain carbon iron which exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness. Combining the correct face thickness with a 32 vane casting provides superior heat management and long service life with low rotating and unsprung weight. The straight vane design also makes it possible to use the same rotor on left or right hand mounting locations.
