Brake pedal grind is usually caused by metal to metal contact in the brake system, but you said the pads and rotors were already changed. Was that just the front or the rear, also?
Check around the steering column for any binding wires or wires that may been frayed or lost insulation near the column. Your car isn't a drive-by-wire type, so it can't be a short in that kind of system. In order for the lights on the dash to be caused to flash, their path to ground has to be completed. I have attached schematic diagrams for the ABS circuit and for the instrument cluster in hopes that they will help you trace the fault.
