Keep firm, even pressure at the front brakes with the Carlson Disc Brake Caliper Piston 7122. Seated inside the front caliper, the piston transfers hydraulic pressure from the brake fluid to push the pad against the rotor each time you apply the brakes. It fits as a direct-fit replacement for the 2003-2005 Infiniti FX35, 2003-2005 Infiniti FX45, and 2003-2012 Nissan Murano (all engines).
Front brake application: cataloged for the front caliper position on the listed vehicles.
Hydraulic actuation: designed to travel in the caliper bore so the pad applies and releases with pedal input.
Replacement quantity: the listed applications use two pistons per vehicle.
Sold individually: order two to service the matched front caliper set.
Signs the original piston may need replacing include brake fluid seepage at the caliper, a piston that sticks or drags in its bore, or uneven front pad wear. If a corroded or seized piston is the cause of these symptoms, replacing it with the 7122 helps restore proper caliper movement. Because braking faults can have other causes, diagnose the system before replacing parts, and service the front pistons on both sides together for balanced braking. Manufacturer part number 7122.
