  • (4) GM Brake Caliper Slider Bolts

Installation Note:

Only use full metallic pads on coated rotors.

When utilizing slider bolts, the original slide pin bolt sleeve will not be used.  It must be removed from the caliper as the head of this slide pin bolt has this sleeve function built into the bolt.    The slide pin bolts included will replace both the original slide pin bolt sleeve and the original equipment type slide pin bolt.

Hawk Performance burnishes its High Performance Street brake pads as a final step in the factory, but all brake pads have to be bedded-in with the rotors (new or used) that they will be used against. Properly bedding-in new brake pads results in a transfer film being generated at the pad and rotor interface to maximize brake performance.

Due to the dramatic friction levels produced by the HP Plus series to achieve "race-level" braking, rotor wear, noise, dust, and pad life may be affected.

Learn how to properly Bed-In your brake pads by reading our tech article.  Bedding-In Brake Pad Procedure.

Application Note:

These calipers are 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). They will fit any bracket / spindle designed for the large GM calipers (7” mount width).

Depending on the spindle and rotor size they will not fit in most 14” wheels (nor in 15” drum brake wheels).
