Re: Power Brake, 55 Patrician

The condition you are describing is from brake fluid that has been sitting many years, exposed to air and moisture and has crystallized.
This will occur in conventional master cylinders, power brake units and even power window/top hydraulic systems and yes even on dual master cylinders. It is not unique to Bendix type.

Fluid should be flushed and changed every 3 years according to some current car manufacturers. If your engine oil had not been changed in 10 or 20 years of driving the engine would probably fail too.

Any unit if not properly maintained or rebuilt will be prone to failure. Choose a rebuilder that other hobbyists have had success with
