Carlson Disc Brake Caliper Piston P/N:7150
Restore smooth, even clamping force at the rear brakes with the Carlson Disc Brake Caliper Piston, MPN 7084. This rear brake caliper piston is a direct-fit replacement for the 2007-2009 Dodge Sprinter 3500, the 2007-2015 Freightliner Sprinter 3500, the 2010-2018 Mercedes-Benz Sprinter 3500, and the 2018 Mercedes-Benz Sprinter 3500XD. It transfers hydraulic pressure from the brake fluid to the pad, so it plays a central role in how the rear caliper applies and releases the brake.
Signs the original piston may need replacing include a corroded or pitted piston surface that causes it to stick, a caliper that drags or a pad that wears unevenly, or fluid seepage past the piston. Because these symptoms can have other causes, diagnose the caliper before replacing. If a failed rear caliper piston is the cause, this replaces it. Consult the vehicle service information for the correct fasteners, seals, and brake-bleeding procedure.
What does this brake caliper piston do?
It moves under hydraulic brake-fluid pressure to press the brake pad against the rotor, then relaxes as pressure drops, applying and releasing the rear brake.
