Last year I changed out my hydro boost out for a vac booster. I am still running the same MC but now I am having an issue with the brakes slowly engaging themselves while driving. At first I though maybe too much vac to the booster so I unhooked it. Still the same problem. Initially I found that the pushrod was too long so I adjusted it to only engage with pedal and still doing the same thing. Any ideas? I never had any issues with this MC on the hydroboost other than it was too much assist if that makes sense.
Setup is as follows:
Vac assist from an '87 Jeep Wrangler
MC for late 70's 1 ton chevy, removed the residual pressure valves. Has run no problems since I replaced the MC in 2008...No proportioning valve.
