Carlson Disc Brake Caliper Piston P/N:7030

Keep firm, responsive braking pressure moving to your pads with the Carlson Disc Brake Caliper Piston (P/N: 7030). This front caliper piston drops in as a direct-fit replacement for the 2018-2020 Buick Enclave, 2017-2020 Cadillac XT5, 2020 Cadillac XT6, 2019-2020 Chevrolet Blazer, 2018-2020 Chevrolet Traverse, and 2017-2020 GMC Acadia — all engines, with 4 used per vehicle. Seated inside the front brake caliper, the piston takes hydraulic pressure from the brake fluid and drives the brake pad against the rotor when you press the pedal.

• Direct-fit front piston: Cataloged for the front position on the listed applications.
• Hydraulic actuation: Transfers fluid pressure to press the pad against the rotor for clamping force.
• Application coverage: Each listed vehicle uses 4 pistons — see the Buyer's Guide tab for the full fitment.

Signs a caliper piston may need replacing include fluid seepage at the caliper, a piston that sticks or won't retract, or uneven pad wear. If a worn or corroded piston is the cause of these conditions, this replaces it. Always inspect the caliper bore and seals, and diagnose the underlying cause before installing. For balanced braking, service the pistons on both sides of the axle together.
