Master cylinder/brake lines placement question 82 G10 - February 23rd 2018 1:36 am
My van is losing assist when braking. New master cylinder, and power booster. Don’t know anything about the porportioning valve but was told it is working properly. But buddy thought my lines were hooked up backwards to the master cylinder, not saying this is probably the problem but was curious. Any help is greatly appreciated! Gonna try to attach photos of mine.
