Soft/sinking brake pedal
97 F350. NEW rear drums & shoes. front pads/rotors less than 8 months old. Bled the crap out of brakes and installed a new master cylinder. I still have a squishy pedal, which when pressed hard, sinks almost to the floor. When pedal goes down, the brakes still hold. I've seen one post where the member put the truck on a sever down angle, nose down and bled brakes. This angle caused the master cylinder to be level allowing the air to finally escape.
Anybody have this issue? I'm going to try to bleed them Monday after my weekend night shifts.....Tired of this situation.
Also - there is no way the vacuum booster can cause this issue? I know it can cause brakes to apply if the internal spring breaks, but I see no way it can cause this issue..
