Turn brake-fluid pressure into stopping force with the Carlson Disc Brake Caliper Piston 7815. Seated inside the caliper, this piston uses hydraulic brake-fluid pressure to push the brake pads against the rotor, making it a key piece of hardware any time you service the friction material. It installs as a direct-fit replacement for both front and rear disc brake calipers on the listed applications, including the 1998-2011 Ford Crown Victoria, 1998-2004 Ford Grand Marquis, 1998-2000 Isuzu Hombre, 2003-2005 Lincoln Aviator, 1999-2011 Lincoln Town Car, 1998-2011 Mercury Grand Marquis, and 2003-2004 Mercury Marauder — see the Buyer's Guide tab for the full list.
- Hydraulic actuation: uses brake-fluid pressure to force the pads against the rotor.
- OE-quality specs: matches Original Equipment (OE) quality specifications.
- Quality materials: built with quality materials to hold high tolerances.
- Corrosion-resistant: corrosion resistant to stand up to harsh roads.
Brakes work as a system, and service experts agree that when the friction material is due for replacement, the caliper hardware is too. If a worn, pitted, or seized piston is the cause of your braking trouble, replacing it helps restore proper caliper operation. Sold individually.
