Academic question.

Many of us have installed the dual master brake system. Today I was thinking about my installation and a question came up. With the two independent systems, how do you know both systems are bled properly? Could you have one system perfect and some air in the other and not know it because you won't have a mushy pedal?

I know when we bled mine the pedal got stiff after the rear was done but we still had to do the front. Same for a brake failure, other then noticing loss of braking, will you notice anything in the pedal movement?
