i have a 94 f350,abs and brake light comes on and brakes little soft,when i turn truck off and start it again the lights go off,,when i hook up a trailer and have to stop a little hard the rear brakes will lock up,,if you think it is the rabs can i bypass it or will i have to buy a new one(if it is the problem)

 

check your fluid. Might want to find out why your peddle is soft. That is normally signs of air in the system. Is your peddle low or close to the floor when braking? I would also try changing the sensor in the pumpkin as they good bad often and will cause ABS problems.

 

i have new master,and also replaced speed sensor on rear end

 

full of fluid and have also blead system 3 times
