Carlson Disc Brake Caliper Piston P/N:7205

Transfer hydraulic pressure to the brake pads with the Carlson Disc Brake Caliper Piston (P/N 7205). Housed inside the brake caliper, this piston converts brake-fluid pressure into the clamping force that pushes the pad against the rotor each time you apply the brakes. It is cataloged for both front and rear caliper positions and drops in as a direct-fit replacement for the listed applications, including the 1978-1979 Audi Fox, 1979-1981 Volkswagen Dasher, 1980-1986 Audi 4000, 1981-1985 Audi Coupe, 1995-2002 and 2006-2009 Land Rover Range Rover, 1999-2004 Land Rover Discovery, 2002-2008 Mercedes-Benz G500, 2005-2009 Land Rover LR3, 2006-2009 Range Rover Sport, and 2009-2013 Mercedes-Benz G550 (see the Buyer's Guide tab for the full list).

• Core function: transfers hydraulic pressure from the brake fluid to the pad, applying clamping force at the rotor.
• Front and rear: cataloged for both front and rear caliper positions, depending on the application.
• Quantity per vehicle: the listed Audi and Volkswagen applications use two pistons, while the Land Rover and Mercedes-Benz applications use four — order the number your vehicle requires.
• Signs it may need replacing: fluid seeping at the caliper, or a piston that is seized, pitted, or corroded and causing a dragging or sticking brake.

A common replacement item during a caliper rebuild, this piston helps restore proper caliper operation if a worn or corroded original is the cause of the problem. Diagnose the source of any braking issue before replacing. Manufacturer part number 7205.
