95 K1500, been sitting, brake fluid res empty

Update:

I have inspected the entire brake system, I have not been able to locate a/any spilled/leak fluid. The gasket below the cap on the master/cly reservoir was not (totally) in place, this now has me wondering if the brake fluid may have evaporated ?

I filled the fluid, pumped up the brakes, they seem to be working fine. I will be keeping my eyes open for problems.
