Keep hydraulic clamping force moving where it counts with the Carlson Disc Brake Caliper Piston 7819. This caliper piston uses brake fluid pressure to force the brake pads against the rotor, and it drops in as a direct-fit replacement for a wide range of medium-duty trucks — including the 2003-2009 Chevrolet C4500/C5500 Kodiak and 1997-2009 C6500/C7500 Kodiak, the matching GMC C4500/C5500 and C6500/C7500 Topkick, the 2000-2002 Ford F-650 and F-750, the 2005-2007 Hino 268, and the 2004-2006 Isuzu FTR and FVR. It is cataloged for both FRONT and REAR disc-brake caliper positions on the listed applications; see the Buyer's Guide tab for the full vehicle list.
Brakes work as a system — when the friction material is due, the caliper hardware is worth servicing at the same time. If a seized, scored, or corroded original piston is the cause of a dragging or uneven-braking caliper, this replaces it.
Interchange: FH7819 · DPS85494
This part cross-references / interchanges with the following part numbers:
What does the Carlson 7819 caliper piston do?
It uses brake fluid pressure inside the caliper to push the brake pads against the rotor, converting hydraulic pressure into the clamping force that slows the vehicle.
Does this fit front or rear brakes?
The catalog lists this piston for both FRONT and REAR disc-brake caliper positions on the covered applications. Confirm your vehicle in the Buyer's Guide tab before ordering.
Which vehicles does the 7819 fit?
Medium-duty trucks such as the Chevrolet Kodiak and GMC Topkick C-series, Ford F-650/F-750, Hino 268, and Isuzu FTR/FVR. See the Buyer's Guide tab for the complete list of years and models.
What are the interchange numbers?
This piston cross-references FH7819 and DPS85494. Matching a brand-and-number search to your original part helps confirm you are ordering the right piston.
Should I replace other brake hardware too?
Brakes are designed as a system. When the friction material is ready to be replaced, industry brake-service practice is to service the caliper hardware at the same time for consistent performance.
