Yes! That worried me, but I kept flushing/bleeding the entire system until clear brake fluid was flowing out. I might flush the system again after a few months. Brake fluid is cheap. We have heard about rust/corrosion in the calipers and MC's on this and several other threads. Fellow inmates, flush the system at least once yearly.
