I have a 1988 Gmc
Sierra 1500, and my brakes are soft(goes to the floor with little to no resistance). This is after i replaced the brake booster , and the master cylinder. Anyone have any ideas I don't know what to do next already put 200$ worth of parts on it , which didn't fix the problems , and
yes I've bled the brakes on all 4 lines , and the on the ABS system. and its coming out
with no air in the lines!
