Thanks for you time on the reply, I’ll be sure to take a look at all of that before going for the booster

Tried that and it took a couple pumps to get the pressure back up after stopping

Fluid has been consistent. Had it up on a 4 post yesterday and check every inch of that linbe. No leaks but it is rusty.

First time posting on here. Recently picked up my first MJ and have been doing repairs to get it road ready. Spent the day trying to get the brakes working better and am wondering if I'm on the right track. When the engine is off pedal is solid but once started/driving it losses all pressure and needs to be pressed right to the floor for it to come to a full stop.. thinking bad booster? there's vacuum right up to the housing.
