the MC needs to be bled.

it's fairly simple, easiest with the power bleeder, but if you get a set of bleeder hoses from an auto parts store, it can be done in the car.

disconnect the brake lines, hook up the bleeder hoses, and loop them back into the reservoir.
pump the pedal until all air is out of the lines, then repeat with each output line.
