How to Install F150 Electric Brake Controls

The Ford F-Series is a family of full-size pickup trucks in continuous production since 1948. The F150 pickup has a rated carrying capacity of 3/4 ton, although modern versions of this truck can carry much more than that. The braking system on late-model F150s includes an anti-lock braking system, or ABS, as standard equipment. This feature allows a vehicle to stop during an emergency without locking the wheels. The brake controller on an F150 is also known as the hydraulic control unit, or HCU.

Instructions

1

Remove the negative cable from the battery with a socket wrench to ensure the engine doesnt start during the procedure. Disconnect the air cleaner assembly.

2

Disconnect the four fittings that connect the brake lines to the HCU with a socket wrench, and detach the brake lines from the HCU. Remove the three bolts that attach the HCU bracket to the vehicle frame, and disconnect the HCU bracket.

3

Remove the two nuts that attach the HCU to its bracket with a socket wrench, and disconnect the HCU from its bracket. Detach the ABS module from the HCU.

4

Attach the ABS module to the new HCU. Install the HCU to its bracket, and tighten its retaining nuts to 80 inch-pounds with a torque wrench. Connect the HCU bracket to the vehicle frame, and tighten the mounting bolts to 18 foot-pounds. Attach the brake lines to the HCU, and tighten the fittings to 13 foot-pounds.

5

Connect diagnostic tool Worldwide Diagnostic System 418-F224 to the vehicles data link connector. Bleed the ABS, and use the diagnostic tool to clear any ABS faults. A qualified mechanic typically performs this step.
