Rebuilding a sticking or corroded brake caliper starts with a sound piston. The Carlson Disc Brake Caliper Piston 7162 seats in the caliper bore and transfers hydraulic pressure to the brake pad, pushing it against the rotor when you apply the brakes. It installs as a direct-fit replacement across the listed applications, including the 2002-2009 Chevrolet Trailblazer, 2004-2007 Buick Rainier, 2020-2022 Ford Explorer and 2015-2021 Kia Sedona — see the Buyer's Guide tab for the full list.
If a corroded or seized piston is the cause of a dragging brake, uneven pad wear, or a spongy pedal, replacing it addresses that component; diagnose the caliper and hydraulic system first, and follow the service procedure for correct fasteners and bleeding. Manufacturer part number 7162.
