Transfer hydraulic force to your front pads with the Carlson disc brake caliper piston (P/N 7975), a front-brake replacement piston that drops into the caliper bore on the 2007-2009 Dodge Sprinter 3500, 2007-2015 Freightliner Sprinter 3500, and 2010-2016 Mercedes-Benz Sprinter 3500. See the Buyer's Guide tab for engine-level details.
Brakes are engineered as a system, and every piece has to work together. The caliper piston uses brake fluid pressure to force the brake pads against the rotor to slow the vehicle, which is why industry brake-service experts recommend renewing the hardware whenever the friction material is replaced.
Signs this piston may need replacing include fluid seepage at the caliper, a sticking or dragging front brake, or pistons that are pitted or corroded during a pad job. If a failed or corroded piston is the cause, this part replaces it.
