I am sure this is not the problem, but....
Take the front master apart, make sure there is NO little cup with a flapper
valve forward of the spring (away from the reservoir). It will not be there
in this case, but check anyway. I had the same thing occur, and 2# or not,
removing it stopped the problem.
