Keep the front brakes clamping smoothly with the Carlson Disc Brake Caliper Piston 7030, the hydraulic piston that transfers brake-fluid pressure inside the caliper into clamping force on the brake pads. It installs as a direct-fit front-caliper piston for the 2017-2020 Cadillac XT5, 2017-2020 GMC Acadia, 2018-2020 Buick Enclave, 2018-2020 Chevrolet Traverse, 2019-2020 Chevrolet Blazer, and 2020 Cadillac XT6 [All engines].

  • Front caliper piston: rides in the caliper bore and extends under brake-fluid pressure to press the pad against the rotor.
  • Application quantity: the listed vehicles use 4 per vehicle — order the full count for a complete front-axle job.
  • Direct-fit replacement: a front caliper piston for the listed applications.
  • Serviceable wear item: if a corroded, pitted, or sticking original piston is the cause of brake drag or uneven pad wear, this replaces it.

Signs the original front caliper piston may need replacing include a caliper that drags or won't release, uneven pad wear, or brake fluid weeping past the piston. Diagnose the cause before replacing, since these symptoms can have other sources. Best practice is to service both sides together for balanced braking. Manufacturer part number 7030.
