Thanks Jeff. I think that if it were air in the system then the brake pedal would be consistantly low except when they are pumped... Constant low pedal would also happen with worn pads. The situation I find is that the pedal functions well at times and at other times it seems to slip while braking. (like if a wheel cylinder is leaking badly) However I am not losing fluid.

If it is the Master cylinder... why do you think it is too difficult to rebuild? Is there something about MB cylinders that make them difficult to rebuild? The cost you mention above.. is that for new brakes or a master cylinder?
