Bring firm, even clamping back to your front disc brakes with the Carlson Disc Brake Caliper Piston 7582. This front-position caliper piston uses hydraulic brake-fluid pressure to force the brake pads against the rotor, doing the mechanical work that turns pedal pressure into stopping force. It installs across a wide range of applications listed below.
- Core function: Transfers brake-fluid pressure to push the pads against the rotor.
- Steel construction: Made of steel to match Original Equipment (OE) quality specifications.
- Corrosion-resistant: Helps resist corrosion from harsh road conditions.
- Piston dimensions: 2 in (50.8 mm) diameter, 1-13/16 in (45.7 mm) height.
Signs this piston may need replacing: a corroded or pitted piston that sticks or seizes, brake fluid weeping past the seal, or uneven pad wear. If a failed caliper piston is the cause, this replaces it during brake service; brake experts recommend refreshing hardware whenever the friction material is renewed. Diagnose the cause before replacing.
