There are a couple of things that would make the brakes lock up, It could be the callipers are binding up or the abs porpotion valve is bad. The abs system is expensive so I would go with the callipers first. You can take off the wheel and then the calliper using a brake piston retractor push the piston back in. If the brake pads are worn put new ones on this will off set where the piston is hanging up.
