Return PolicyIf 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.

Customers appreciate the superior stopping power the brake calipers offer due to their large bore size, noticeably improving their vehicles' safety. Many note an easy installation and substantial improvement in braking, even without power assistance. Customers highlight the product’s compatibility with different cars, from vintage models to street racers, and the impact on front brake bias. Quality construction, addition of pads and bolts, corrosion-resistant coating, and the product’s ability to be painted received positive mention. It’s a well-priced, effective upgrade from standard and OEM products and provides an excellent performance for its price.

I replaced the original 2 3/8 calipers on my mustang 11 front suspension in my 33 Ford. Brakes were always just ok, could never lock up the wheels in a panic stop. I increased the master cylinder size from 7/8 to 1" and installed these 2 3/4" calipers. I now have a firmer, higher pedal and I can lock up the wheels. Not that I want to but I'm able to. And with a little grinding I was able to reinstall my 14" wheels. I am an NSRA safety team inspector so I was careful how much (little) I ground off the slide bolt ears. Very satisfied with the results.

Swapped out both front calipers on my 02 2wd s10. Parts bolted right on and included brand new hardware to attach them AND PADS also. They are definitely bigger and better than the stock equipment.

Easy to install if you already use metric calipers. Once pads are bedded in, the stopping distance is noticeably less. New vs reman calipers should last for awhile.

I don't see any provision for parking brake, emergency brake. Did I overlook it. Street legal cars here must pass inspection with a suitable parking brake.
