Keep firm, even pressure on the rear brake pads with the Carlson Disc Brake Caliper Piston 7192, the component that transfers hydraulic pressure from the caliper bore to the pad backing plate. It fits the rear brakes of the 2019-2020 Freightliner Sprinter 1500, 2019-2021 Freightliner Sprinter 2500, 2019-2021 Mercedes-Benz Sprinter 1500, and 2019-2021 Mercedes-Benz Sprinter 2500 (All engines).
When you apply the brakes, fluid pressure drives this piston outward so it presses the pad against the rotor; when you release, it retracts to allow the pad to relax off the disc.
- Rear caliper application: designed as a direct-fit replacement for the rear brake calipers on the listed Sprinter applications.
- Transfers braking pressure: travels within the caliper bore to push the pad against the rotor and retract when the brakes are released.
- Replaces a worn piston: if the original is corroded, seized, or scored, this replaces it.
A worn or seized piston can cause uneven pad wear, brake drag, or a soft pedal; if the piston is the cause, this replaces it, but diagnose the caliper before installing. The listed applications use two pistons at the rear axle, so order the quantity your repair requires. Replace brake components on both sides together as a matched pair for even, balanced braking.
