My Master cylinder is going. Least thats what I think it is. Brake pedal slowly sinks to floor. Fortunately brakes do still work fine though. Classic symptom of needing new master cylinder. Loosing no fluid anywhere. So before I replace master cylinder which will require then bleeding brakes I figured I would write in here to brickboard for any tips or advice on how to do this job quickly and efficiently with no hassles. Thanks in advance.
