The Carlson Disc Brake Caliper Piston 7235 is the hydraulic piston that rides inside the rear disc brake caliper, translating brake-line pressure into the clamping force that presses the pad against the rotor. It installs as a direct-fit replacement rear caliper piston for the 2010-2015 Chevrolet Cruze, 2011-2015 Chevrolet Volt, 2012-2017 Buick Verano, 2013-2017 Buick Encore, 2013-2016 Chevrolet Sonic, 2013-2017 Chevrolet Trax, 2014-2016 Cadillac ELR, 2016 Chevrolet Cruze Limited, and 2016-2019 Buick Cascada.
Best practice is to service the rear brakes as a matched pair for even, balanced braking. Manufacturer part number 7235.
