Well, I only blew the valve out. Did not take it apart. Put it back together
and front brakes work fine, but not enough pressure at rear to expand brake
linings. I think valve is bad..Truck is farm use only and not worth what I have
already spent on it. Think I will leave valve hooked up for front brakes, plug
valve openings that operate the rears, and run a direct line to rear bypassing
valve. As for as warning light, it was never hooked up to begin with. I guess the
worst that can happen is I run thru a fence. Trk is in good shape including motor,
but trying to sell it would not be worth what I have invested..
