The Alcon ALACIR1551K40HZLL-RT021A01 is a direct-replacement front left (driver side) 6-piston brake caliper designed for use with the Alcon big brake kit for the Ford Ranger and Ford Bronco 2.3L. This is a genuine Alcon replacement caliper sold as a single unit and comes with brake pads pre-loaded into the caliper, making it a straightforward service part for owners of the Alcon BKF1551K61 front brake system.
