One needs to careful when bleeding using the brake pedal, so a board or something thick should be placed under the pedal to stop it from going to the
floor as it could jam the mc piston. A stuck mc piston can be seen when it is removed as the piston doesn't return all the way. When I replaced all
the calipers on the '11, although never having a problem with the vacuum bleeder, this time couldn't get a hard pedal, so I had the wife pump the pedal
and when done, finally a hard pedal.

I'd bleed them again.
