For v6 Camaro, the front and back caliper bracket bolts are different.
(v8 brembo brakes may or may not be same, i have no experience with them)
One time use only, replace any time a caliper bracket bolt is removed.
This is specifically for the bolts that hold the bracket on (required when replacing rotors), not the sliding bolts that the caliper "floats" on. See attached images.
Front:
Part: Dorman 14947 (available at most autoparts stores)
Qty needed: 4 (2 per side)
Torque: 60Nm (44lbft) + 90 degrees
Price: I think i paid $14 ($7 for a set of 2 at autozone)
Rear:
Part: ACDELCO 92139142 (only available at GM dealers or parts sites)
Qty needed: 4 (2 per side)
Torque: 40Nm (30ftlb) + 90 degrees
Price: About $40 (sold individually for about $8, plus shipping from a GM parts site)
If anyone finds an aftermarket bolt for the rear then i'd love to know. It's frustrating spending $40 on just bolts when servicing the rear.
Hope this clears it up!
