Had a moderate, wheel turning pull to the right in my '94 1/2 2wd. Changed the left caliper then the hose to no effect. While out test driving i made the ABS function. The pull is gone and hasn't returned. Had a shop relate a similar ABS related prob: after stopping the pedal would go to the floor, activated the ABS while testing and the problem went away. The story seems to be that if the ABS doesn't get used then the valving starts leaking until system activation reseats them.
