Dumb brake master cylinder problem/question...my 1990 454SS has some seriously low brakes. Upon inspection, the MC was extremely low on brake fluid. About 10K miles ago, I changed out two of the rear wheel cylinders that were leaking, and have reinspected the lines at all 4 corners and no signs of leaking.

Where is my brake fluid going? Is it leaking into the brake booster? How do I check for that? And if it is leaking into the booster, how do I fix- replace, extract the fluid, or is there a diaphragm repair kit for it?

I have a had a couple of master cylinders leak in to the brake booster, and if left that way very long the brake fluid eats up the seals in the booster and then the engine sucks the brake fluid straight in. I also had my forklift do the same thing.
