I have a 1987 honda wagovan 4x4 and I can't seem to get the mush out of the
brake pedal. I have replaced the master cylinder twice (and bled it to
specs), i have replaced 3 lines and I brake cylinder and have pressure and
manually bled the brake symstem numerous times. I also tightened up the rear
brake shoes so they are snug too. There is no evident leak anywhere. The
pedal will all the way to the floor and if on grass or gravel all wheels do
lock up eventually. The braking power on the road stinks. I'm out of ideas
and am looking for help!
