Posted April 9, 201015 yr comment_315485 Yesterday we managed to open up stuck rear brakes. After that my mechanic friend bleeded the system but no pressure on brakes. I made a little run on the yard and if i pump brake several times quick, it'll stop but if i press just once nothing happens. So is this caused by bad master cyl or does master vac got something to do with this?
