Got an brake problem that cant seem to figure out. Got a 1977 Travelmate RV. Runs like a dream. 454 bbc 400tranny. Interior is beautiful... for the 70's.... the seats cushions are stiff as if they were never used. Anywho... the brakes wont work. Replaced the master cylinder, bled it all numerous times. Even tried several different methods of bleeding it. The only thing that i can think of might be the problem is the power assist unit. Any suggestions? The vehicle is on a farm right now most likely under about 6 feet of snow, so i wont be touching it til the spring/summer. Would love to bring it in the city, but with no brakes, it... well, yea. Thinking of pulling the motor out and setting it on fire while i dance naked around it with a stick. Any suggestions would be great. Even the absurd. I'll try about anything.
