2014 Ford Fiesta ABS Module Replacement

This issue started with a brake pedal that seemed to stick occasionally. This eventually lead to the front passenger brake locking up randomly as though a valve in the ABS was stuck. This was diagnosed by removing the brake line at the ABS and still seeing pressure (it wasn't a collapsed brake hose at the caliper). Swapping out a used ABS module solved the problem, but be aware it is tedious, and there are programming issues you need to address to clear all codes.
