I concur that the brake lines are exceptional through Kaiser's. The problems arise when I go the cheap route using the Crown master and wheel cylinders. The bleeder valves are 8MM, then the mount holes do not line up with the original dust shield at the wheel cylinders. Also the inlet line hole has to be indexed for the line to match. After some research, the American made Wagner wheel and master cylinders fit right the first time. I've had the Crown items installed for at least 4 years, without much issue except for the constant two pumps for every stop.

As a note, there is an outfit out there that makes a check valve that you can put in line that retains some line pressure to aid in not having to pump the brakes each time.
