There is a possibility a ABS sensor is going bad. It's best to have a repair shop hook up a scan tool to the vehicle find the real problem. The ABS system has more than one sensor to cause this problem. So, a Automotive Scan tool is required to find out which is the faulty sensor.

you have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem

If you forced the pads back into the calipers without loosening the bleeders you probably forced gunk into the abs modulator valves. Sometimes doing the automated bleed proceedure (need Tech or Bi Directional Scanner) will bring things back to life.
