Keep your front-left brake corner clamping smoothly with the Raybestos R-Line Semi-Loaded Disc Brake Caliper FRC12276, a remanufactured brake caliper and bracket assembly that installs as a direct-fit replacement for the listed applications. It fits many trucks, among them the 2012 Ram 1500, 2011-2018 Ram 2500 and 2009-2010 Dodge Ram 2500; see the Buyer's Guide tab for the full list. This is the front-left unit; the caliper applies the hydraulic clamping force that presses the brake pads against the rotor.
This floating cast-iron caliper uses a 2.358 in (59.9 mm) piston and an M10x1 bleeder screw thread, with a 16.000 mm bracket mounting hole at a 2.500 mm thread pitch. Sold individually; replacing both sides as a matched pair is recommended for balanced braking. Country of origin: Mexico.
