Installed new brake booster and master cylinder from Advance (total kit) and the reservoir raises up like it is trying to pop off the master cylinder when you push in the brake. ???  :o ??? Have bled brakes, new shoes, rotors, wheel cylinders and have replaced the booster/master cylinder kit twice thinking it was a defect but same issue. When I take the cap off the reservoir air does push out. ??? What could be the issue? Has anyone had this issue before? Solutions?

What do you mean it raises up? Is your firewall rotted or something? Post pics or a vid or explain better.
