Dynamic Friction 331-54643 rear left brake caliper for the 2005-2014 Ford Mustang squeezes the pads against the rotor to slow the wheel.
Pulling to one side, a burning smell after a drive or fluid at the wheel can mean a caliper is sticking or leaking, though pads, a brake hose or a rotor can produce similar symptoms. With the engine off and the wheel cool, look for wetness around the caliper, and have a shop find the cause before you replace this disc brake caliper.
It is a direct-fit replacement for the 2005-2014 Ford Mustang. Plan to replace the rear calipers as a pair, one on each side of the axle; this listing is the rear left only, and the rear right is a separate part.
