Keep hydraulic pressure pushing your front brake pads squarely against the rotor with the Carlson Disc Brake Caliper Piston 7090. This front-axle piston rides inside the disc brake caliper, converting brake-fluid pressure into the clamping force that presses the pad into the rotor. It's a direct-fit replacement for the front brakes on late-model GM full-size trucks and SUVs, including the 2019-2021 Chevrolet Silverado 1500 [All], 2019-2021 GMC Sierra 1500 [All], and 2021-2022 Cadillac Escalade [All] — see the Buyer's Guide tab for the full list of 10 applications.

  • Front-position caliper piston: serves the front disc brakes on the listed applications.
  • Hydraulic actuation: transfers brake-fluid pressure to the brake pad to apply the caliper.
  • Application quantity: the listed vehicles call for four per vehicle (engine: All).
  • Direct fit: designed to install in place of the original piston on the listed applications.

Signs the original piston may need replacing include a sticking or seized piston, brake drag, uneven pad wear, or fluid seeping past the piston seal. Because these symptoms can have other causes, diagnose the brake system before ordering; if a failed caliper piston is the cause, this replaces it. Manufacturer part number 7090.
