Carlson Disc Brake Caliper Piston P/N:7846

Renew a key hydraulic wear point in your front brakes with the Carlson Disc Brake Caliper Piston 7846, a direct-fit replacement for the front brakes on a wide range of GM cars and minivans. It fits many vehicles, among them the 2000-2005 Chevrolet Impala — see the Buyer's Guide tab for the full list.

The caliper piston rides in the caliper bore and transfers hydraulic pressure from the brake fluid to push the brake pad against the rotor. A pitted, scored or corroded original can drag, stick or weep fluid past the seal.

• Function: Presses the pad against the rotor under hydraulic pressure to apply the front brakes.
• Direct-fit design: Direct-fit replacement for the front caliper piston on the listed applications.
• Renews a wear point: If a seized or corroded piston is behind a sticking caliper, uneven pad wear or a fluid leak, this replaces that component.

The listed applications use two per vehicle (one per front caliper). Diagnose the cause of your brake condition before replacing, and service both sides as needed for balanced braking.
