Put dependable hydraulic clamping force back into your front brakes with the Carlson Disc Brake Caliper Piston 7984. This front caliper piston uses brake-fluid pressure to force the brake pads against the rotor so your vehicle can slow and stop. It's a direct-fit replacement for the 2008-2009 Pontiac G8 [All], which uses two pistons per vehicle.
Brakes work as a system, and the piston is a key piece of that hardware — many brake-service experts recommend refreshing it whenever the friction material is replaced.
If a worn, scored, or seized piston is behind dragging brakes or uneven pad wear, this replaces it. Diameter 1-11/16 in (43.2 mm), height 2 in (50.8 mm). Sold individually; the Pontiac G8 uses two per vehicle, so order accordingly. Country of origin: China.
