Carlson Disc Brake Caliper Piston P/N:7101

Turn brake-line hydraulic pressure into pad-clamping force with the Carlson Disc Brake Caliper Piston 7101. This piston rides inside the front disc brake caliper, where pressurized brake fluid pushes it outward so it presses the brake pad against the rotor each time you apply the brakes. It's cataloged for the front calipers of the 2006-2013 Chevrolet Impala, 2006-2011 Buick Lucerne, 2006-2011 Cadillac DTS and more listed applications below.

• Mechanical job: converts pressurized brake fluid into the clamping force that pushes the pad onto the rotor.
• Position: front disc brake caliper piston for the listed applications.
• Quantity: the listed applications use four pistons per vehicle (qty 4); order enough to match your caliper configuration.
• Signs it may need replacing: brake fluid seepage at the caliper, a piston that sticks or won't retract, dragging brakes, or uneven pad wear.

If a worn or corroded piston is the cause of a sticking caliper or a soft pedal, this replaces it. As a best practice, service the calipers on both sides together for even, balanced braking. Diagnose the underlying cause before replacing, since these symptoms can have other sources. Fits: 2006-2011 Buick Lucerne, 2006-2011 Cadillac DTS, 2006-2013 Chevrolet Impala, 2006-2007 Chevrolet Monte Carlo, 2008-2009 Buick Allure, 2008-2009 Buick LaCrosse, and 2014-2016 Chevrolet Impala Limited. Manufacturer part number 7101.
