Carlson Disc Brake Caliper Piston P/N:7204

Deliver firm, even hydraulic clamping force with the Carlson Disc Brake Caliper Piston 7204. This front brake caliper piston is a direct-fit replacement for many vehicles, among them the 2002-2005 Volkswagen Passat, 2001-2005 Audi Allroad Quattro, and 2000-2004 Audi A6; see the Buyer's Guide tab for the full list. The piston sits inside the caliper bore and transfers hydraulic pressure from the brake fluid to push the brake pad against the rotor when you apply the brakes.

• Front position: cataloged for the front brake calipers on the listed applications.
• Hydraulic actuation: converts brake-fluid pressure into clamping force on the pad.
• Per-application quantity: the listed vehicles use 4 pistons — order the quantity your vehicle requires.

A pitted, corroded, or seized piston can cause uneven pad wear, brake drag, or fluid seepage past the seal. If a failed piston is the cause of these symptoms, this replaces it. Inspect the caliper bore and seals during installation, and consult the vehicle service information for the correct bleeding procedure and torque specifications.
