i talked to the guy that rebuilt the unit and he says the problem may be a broken spring in the vacuum control valve.the spring apparently is not serviceable so another valve from another core would have to be installed to hopefully correct the concern.i also talked to him about another concern that just came up,the brake pedal bleeds down when you are at a stop with no leaks.he says that the problem may be with the compensator valve not sealing and allowing brake fluid to bleed back to the bowl in the m/c .so me adding a check valve to the vacuum and correcting the bake pedal staying down was just a coincidence because the problem just returned.looks like its time for some warranty work.
