Carlson Disc Brake Caliper Piston P/N:7147

Push the rear brake pad against the rotor with steady hydraulic force using the Carlson Disc Brake Caliper Piston (P/N 7147). This rear caliper piston is a direct-fit replacement for the 2004-2008 Chrysler Crossfire and a range of Mercedes-Benz models — including the C230, C240, C280, C320, C350, C32 AMG, CLK320, and CLK350 — with each listed application using 4 pistons. See the Buyer's Guide tab for the full year-by-year list.

The piston sits inside the rear brake caliper and transfers hydraulic pressure from the brake fluid to push the pad against the rotor when you press the pedal.

• Rear application: cataloged for the rear disc brake caliper on the listed vehicles.
• Hydraulic actuation: moves under fluid pressure to apply the brake pad against the rotor.
• Per-application quantity: the listed applications use 4 pistons per vehicle.

Signs this part may need replacing include a piston that sticks or seizes, surface corrosion or pitting, fluid seepage past the piston, or uneven pad wear. If a worn or corroded rear caliper piston is the cause of your braking issue, this replaces it — diagnose the cause before replacing.

Manufacturer part number 7147.
