Okay good afternoon Buick peeps so a few months back I had a problem . Believe it or not I’m still having issues new master cylinder a new booster and new wheel cylinders , and unfortunately I still have no brakes with brake light comes on I can stop I have to keep pumping till I get breaks. But when I’m still at the light my car will slowly still move pedal all the way to the ground. I have to put my car into natural and keep my foot on the breaks so I don’t move. Any suggestions out there can really help me out. I was told i have an adjustable push rod? Is this even correct?

The length of the pushrod should not affect the pedal falling to the floor. This is odd, since it sounds like everything hydraulic has been replaced, except hard lines… Did you verify the push rod length like I posted in my video earlier? This is an easy check.
@Smartin im goin to check that myself, lol they said I did get two pushrods with my new booster, some how they didn’t replace that they kept the adjustable one in but I will definitely take that out
Pamela, your loosing hydraulic pressure somewhere plain and simple. It’s not a rod length thing. New does not mean good these days Very simple, IF there are no leaks, your master cylinder is bad, the fluid is oozing past the piston seals/O-rings.
