Vehicle comes in with no brakes at all. Checked front and replaced pads checked for leaks all looked good. Checked rear brakes all looked good. Bled system from rear to front starting with the wheel on the passenger side. Got brakes but spongy. Brake pedal is hard when there is no power assist but when I start the truck then the brakes get spongy. Checked for leaks at the master cyl. To booster to see if maybe the seals in the master cyl were leaking into the booster but all was dry. Wheel cylinders as well as the calipers are all good. There is a possibility that the master cyl. May have been replaced prior to bringing it to my shop. I'm thinking that if the master cyl. Wasn't bled then maybe it could cause the problem but as many times as I bled the system it should have taken care of any air in the system. Any ideas?
have the same problem?
