Hi everyone...I just bought a t-bucket a few weeks ago and I'm trying to diagnose all of it's issues . The first problem was a hard brake pedal with very little stopping power. I replaced the master cylinder and a section of rear brake line. When I disconnected the the residual valve it appeared that a water was flowing out of the line. Aside from the obvious...flushing out the system with fresh fluid...is there anything else I should do?
