Dynamic Friction 331-40133 front left brake caliper for the 2011-2018 Ram 2500 and other vehicles squeezes the pads against the rotor to slow the wheel. If a leaking or sticking caliper is the problem, this disc brake caliper replaces it.
A caliper that is leaking or sticking can show up as the vehicle pulling to one side, a pad worn more than the others, or brake fluid around the caliper. Before you replace it, rule out worn pads, a damaged brake hose or a binding slide pin, since those can produce similar signs.
Covered vehicles include the 2011-2018 Ram 2500, the 2009-2010 Dodge Ram 2500 and the 2011-2018 Ram 3500, plus others. A 2011-2018 Ram 3500 takes one caliper at the front left, so the front right is a separate part ordered on its own, and the two sides are normally replaced together.
