Carlson Disc Brake Caliper Piston P/N:7941

When you press the brake pedal, it's the caliper piston that turns hydraulic pressure into clamping force at the wheel — and the Carlson Disc Brake Caliper Piston 7941 is a direct-fit replacement for the listed applications: the 2008-2010 Honda Accord (all engines) and the 2009-2011 Acura TSX (all engines). It seats inside the rear brake caliper bore and, under brake-fluid pressure, presses the brake pad against the rotor.

• Rear caliper position: cataloged for the rear brake caliper on the listed vehicles.
• Hydraulic actuation: transfers brake-fluid pressure to the pad and retracts as the pedal is released.
• Signs it may need replacing: a rear brake that sticks or drags, brake-fluid seepage at the caliper, or a corroded or pitted piston.
• Sold individually: the listed applications use one piston per the Buyer's Guide.

If a worn, seized, or corroded piston is the cause of your rear brake trouble, this piston replaces it; inspect the caliper bore, seal, and dust boot during installation and diagnose the underlying cause before replacing. Servicing both rear calipers together is good practice for even, balanced braking. Manufacturer part number 7941.
