After honing the original slave cylinders and master cylinder rebuilds on my wife's '36 1.5 ton, I had great brakes for a full year. The shoes are all good and there are no leaks. Now after sitting 3 months I take it out for a cold February run and my brake pedal is rock hard and I only the slightest bit of brakes, almost went through my fence. I checked fluid level and it's up. No matter what I do I can not get my brakes back. I know I've got to go back into the system again but has any one been here before? The temp. was in the mid 30's but I don't think I had any water in the system to actually freeze any thing up.
