Info

If you are using 1978-88 GM Metric style brake calipers your choices of piston sizes are pretty much limited to 2-1/2". This isn't bad unless you want to 'tune' your braking by using different size calipers front to rear. By using a larger 2-3/4" piston you will increase the braking force at a wheel over a wheel using a smaller piston.

Bleeder and inlet are both 10mm-1.5 inlet allowing the caliper to be used on either side. Plus, these calipers have been ground smooth to make them easier to paint.

Includes pads and hardware. Sold as EACH.

  • 20% increase in stopping power over stock calipers
  • Can used on the left and right sides
  • Extra ribs have been added internally while unnecessary weight was removed
  • Lighter, stronger, has more stopping power than OEM calipers
  • Utilizes GM metric style D154 brake pads
  • Each caliper includes:
    • brake pads
    • slide pins
    • banjo bolt
    • washers
    • bleeder screw
