Carlson Disc Brake Caliper Piston P/N:7953
The Carlson disc brake caliper piston (P/N 7880) uses brake fluid pressure to force the brake pads against the rotor, making it a vital piece of caliper hardware for the rear brakes. It's a direct-fit rear caliper piston for the 2008-2014 Ford E-150, 2008-2014 Ford E-250, 2008-2019 and 2021 Ford E-350 Super Duty, 2011-2012 Ford TRK, and the 2008 Ford E-150 Econoline — see the Buyer's Guide tab for the full engine-level list.
Brakes are designed as a system, and industry brake service experts agree that when the friction material is ready to be replaced, the hardware is too. Refreshing the piston alongside a pad and rotor job helps the whole assembly work together.
If a worn, seized, or corroded original piston is the cause of a dragging or uneven rear brake, this replaces it. Always diagnose the cause before replacing.
