Carlson Disc Brake Caliper Piston P/N:7188

Restore firm, even brake clamping with the Carlson Disc Brake Caliper Piston 7188, a direct-fit front replacement for the 2019-2022 Toyota Corolla [All] and 2020-2022 Toyota Prius Prime [All]. Housed inside the front caliper, the piston transfers hydraulic pressure from the brake fluid to push the pads against the rotor each time you apply the brakes.

• Front caliper piston: serves the front disc brakes on the listed applications.
• Hydraulic actuation: converts brake-fluid pressure into clamping force on the brake pads.
• Direct-fit replacement: installs as a replacement for the original piston on the listed applications.

Signs the original piston may need replacing include a seized or dragging front brake, uneven pad wear, a piston that won't retract during a pad change, or corrosion and pitting on the piston surface. If a worn or corroded front caliper piston is the cause of your braking issue, this replaces it; diagnose the underlying cause before ordering. The listed applications use 2 per vehicle, so order 2 for a complete front-axle replacement, and inspect the caliper bore and seals during installation.
