ABS brakes

[dww52]

I have a 1995 Buick park AVE with ABS brakes. The other day I hit the brakes on ice, now the front brakes are locked up, if you losen the brake line at the master cylinder and bleed some fluid off the brakes will release. So if you try to drive the brakes are ok for about mile then the brakes start to tighten up, with out even touching the brakes. Can any one give me a idea on what is wrong and how to fix it, or a manual on trouble shooting ABS brakes.

I had a simular problem but with out the ABS system. I replaced the calipers, pads, and Master cylinder before the man at the parts counter ask about the rubber brake hose in the front, well I had always thought if they dont leak they are good, it turned out that it would let the pressure in the caliper, but then it blocked it from coming out, I could open the bleed screw and the pressure let off, but one step on the brake and the wheel was locked up again. I changed the hose and Bamm, it was fixed.
