Carlson Disc Brake Caliper Piston P/N:7040

$17.99

Description

Rebuild your brakes with the Carlson disc brake caliper piston (P/N 7040), the component that uses brake-fluid pressure to push the brake pads against the rotor when you apply the brakes. It's a direct-fit replacement for the front and rear disc brake calipers on the listed applications, including the 2014-2020 and 2022 Ram ProMaster 1500, 2500 and 3500; the 2019-2020 Freightliner Sprinter 1500, 2500 and 3500; the 2019-2021 Mercedes-Benz Sprinter 1500, 2500, 3500 and 3500XD; and the 2019-2020 Mercedes-Benz Sprinter 4500 — see the Buyer's Guide tab for the full list.

Core hydraulic hardware: converts brake-fluid pressure into the clamping force that drives the pads into the rotor.
OE-quality match: made to Original Equipment (OE) quality specifications.
Corrosion resistant: built to resist rust from harsh road conditions.
Held to high tolerances: manufactured with quality materials for a precise fit.

Brakes work as a system, so brake service experts recommend refreshing caliper hardware when the friction material is replaced. If a seized, scored, or corroded original piston is behind sticking or dragging brakes, this replaces it.
