Dry Master Cylinder - No Sign of Leak

[rob love]

Pull a wheel and drum, pull back the cylinder boot, and see what you find. If you find a bunch of white sludge, then you know you have a slow leak and it has dried out in the boots.

Since you are holding pressure, and are not showing visible signs of the leakage, it sounds like you have a few years to go yet. The remote reservoir, while not original, is a good indicator as to the serviceability of your system and it's rate of loss. I am installing them on several of the museum M-series vehicles for safety reasons.
