I have to come back to the original post: why did you do an MC bleed with the MC in the car? Usu this is done on the bench with a new unit to reduce the time bleeding the lines once it's installed.

Do a thorough bleed at each caliper until no bubbles are present at any of them. This may take 1/2 to 1 quart of fluid. Then you should have a firm pedal. If you suspect your brake hoses are old and should be replaced, replace them first.
