I have had all four brakes lock up completely, the first caused a complete replacement of all but the hard piping to be done. the second did not cause the damage, but the truck had to set long enough for the fluid to drain back to the reservoir. The first lockup happened about a week after the front right bearing hub was replaced with a newer model that has a different sensor for the ABS. This is a four wheel disc brake setup.
