Rebuild your brakes with the Carlson disc brake caliper piston 7970, the component that turns hydraulic pressure into stopping force. It uses brake fluid pressure to push the brake pads against the rotor, so a pitted, scored or corroded original can compromise smooth, even clamping. This piston is cataloged for both front and rear disc brake caliper positions on the 2003-2006 Dodge Sprinter 2500 and Sprinter 3500, the 2002-2006 Freightliner Sprinter 2500 and Sprinter 3500, and the 2003-2006 Dodge TRK Sprinter 2500/3500 (NW/Bosch caliper). See the Buyer's Guide tab for the full application list.

  • Core hydraulic role: transfers brake fluid pressure to force the pads against the rotor when you press the pedal.
  • OE-quality build: matches Original Equipment (OE) quality specifications and is manufactured with quality materials held to tight tolerances.
  • Corrosion resistant: built to resist corrosion for service on harsh roads.
  • Service-minded: brake hardware is designed as a system — experts recommend refreshing it when the friction materials are replaced.
