Carlson Disc Brake Caliper Piston P/N:7180

Keep hydraulic pressure moving to the brake pads with the Carlson Disc Brake Caliper Piston 7180. It installs as a direct-fit replacement for the front and rear disc brake calipers on the 2002 Honda Passport, the 2006-2010 Hummer H3, and the 2002-2004 Isuzu Rodeo.

Inside the caliper, the piston is the component that brake-fluid pressure acts on: when you press the pedal, hydraulic force drives the piston outward to push the brake pad against the rotor, and it eases back slightly as pressure releases.

• Hydraulic actuation: transfers brake-fluid pressure to the pad so it clamps the rotor.
• Front and rear: cataloged for both front and rear caliper positions on the listed applications.
• Quantity by application: the Honda Passport and Isuzu Rodeo use 4, while the Hummer H3 uses 2.

A piston that corrodes or seizes in its bore can make a caliper stick, drag a pad, or wear the pad unevenly. If a failed piston is the cause, replacing it helps restore proper caliper travel; diagnose the caliper before ordering. Sold individually, so order the quantity your vehicle requires and service both sides of an axle together for even braking. Manufacturer part number 7180.
