Carlson Disc Brake Caliper Piston P/N:7654
Carlson 7938 rear brake caliper piston for the 2009-2012 Hyundai Elantra and other vehicles uses brake fluid pressure to force the pads against the rotor. It matches OE quality specifications, and catalogs also list it as a disc brake caliper piston.
Fluid around the caliper, uneven pad wear or a pull to one side can mean a piston is leaking or sticking. Before you replace the piston, rule out a seized slide pin or a worn brake hose. Pistons are normally replaced as a pair on one axle; this listing is one piston, and the 2009-2012 Hyundai Elantra takes two.
This rear brake caliper piston is a direct-fit replacement for the 2009-2012 Hyundai Elantra, the 2010-2013 Kia Forte and the 2010-2013 Kia Forte Koup, along with other Hyundai and Kia models. Open the "Vehicles it fits" section to check your exact model and engine.
