Keep front braking pressure moving where it belongs with the Carlson Disc Brake Caliper Piston 7689, a front-position replacement piston for a wide list of GM and Daewoo compacts. It fits the 1991-1998 Buick Skylark, 1992-1996 Chevrolet Beretta, 1992-2005 Chevrolet Cavalier, 1992-1996 Chevrolet Corsica, 1999-2002 Daewoo Leganza, 1992-1998 Oldsmobile Achieva, 1990-1991 Oldsmobile Cutlass Calais, 1991-1998 Pontiac Grand Am, 1992-1994 Pontiac Sunbird and 1995-2005 Pontiac Sunfire — see the Buyer's Guide tab for the full list and engine details.
The caliper piston transfers brake fluid pressure inside the caliper to press the brake pads against the rotor, so a corroded or seized piston can drag, leak, or reduce braking response.
- Pressure transfer: uses hydraulic brake-fluid pressure to force the pads against the rotor when you brake.
- Tight tolerances: manufactured from quality materials held to high tolerances.
- Corrosion resistant: treated to resist corrosion from harsh road conditions.
- OE-quality: matches Original Equipment (OE) quality specifications.
Brakes work as a system — service experts recommend refreshing the hardware whenever the friction material is replaced. Replace pistons on both sides together for balanced front braking.

Frequently Asked Questions
What does the caliper piston do?
It uses hydraulic brake-fluid pressure inside the caliper to force the brake pads against the rotor when you press the pedal.
Which position is this piston for?
This is a front-position disc brake caliper piston for the listed applications. Confirm your vehicle in the Buyer's Guide tab.
Will this fit my vehicle?
It's listed for many GM and Daewoo compacts, including the Chevrolet Cavalier, Pontiac Grand Am, Oldsmobile Achieva and Daewoo Leganza. Check the Buyer's Guide tab to confirm your year and model.
What are signs the caliper piston may need replacing?
Common signs include a piston that seizes or drags, brake fluid leaking at the caliper, or reduced braking response. Diagnose the cause before replacing.
Should I replace both sides at once?
Replacing the pistons on both sides together is recommended for even, balanced front braking. Refresh the caliper hardware whenever the pads are replaced.
