Keep hydraulic braking pressure flowing to the pad with the Carlson Disc Brake Caliper Piston 7188, a direct-fit front-caliper replacement for the 2019-2022 Toyota Corolla and 2020-2022 Toyota Prius Prime (All engines). Seated inside the front brake caliper, the piston is what the brake fluid pushes against to clamp the pad onto the rotor each time the pedal is pressed.

  • Core function: transfers hydraulic pressure from the caliper bore to press the brake pad against the rotor.
  • Front position: cataloged for the front disc brake caliper on the listed applications.
  • Quantity: the listed applications use two — order the correct count for your vehicle.
  • Direct fit: a direct-fit replacement for the listed Toyota applications.

Signs the original piston may need replacing include brake-fluid seepage past the caliper, a piston that sticks or won't retract, or uneven pad wear. If a corroded or seized piston is the cause of your braking issue, this replaces it — diagnose the caliper first. When servicing the front axle, it's good practice to rebuild both sides together for balanced braking. Manufacturer part number 7188.
