Dynamic Friction 331-54649 rear left brake caliper for the 2012-2018 Ford Focus and other vehicles presses the pads against the rotor to slow the wheel. As a disc brake caliper, it uses brake fluid pressure to push its piston against the pad.
A pull to one side under braking, uneven pad wear or fluid seeping around the caliper can mean a sticking or leaking caliper. Worn pads, a scored rotor or a damaged brake hose can sit behind the same signs, so track down the source before you buy.
This caliper fits the 2012-2018 Ford Focus and the 2008-2009 Hummer H2, and both take one at the rear left. This listing is one caliper; the rear right is a separate part, and the other side of that axle is normally done at the same time.
