I am driving from Atlanta to NW Wyoming in my 94 FZJ80. Right now i am near Denver. I started having a intermittent brake problem today and it feels like it is getting happening more often. Some times i press the brakes and i get hard pedal, all the way at the top of the stroke. The brakes still work but take a lot of force. Usually if i let go and try again they work. I think it might be my master or my master not holding a vacuum. The brake calipers, pads and rotors are all good. no leaking fluid or low level of fluid from what i can see. Is there any one way valves or check valves i can test out? Any ideas of what i can trouble shoot? Here is the big question, anyone near Denver have any brake parts or sale that i could pick up tomorrow? I am about to go look i the classifieds right now. Craigs list looks like it is parting a few 80s near Denver but i would rather work with a mud member.
