PULLED VACUUM LINE FROM POWER ASSIST WHILE RUNNING

If the front disc brake calipers could not slide and self center due to corrosion, will fixing them cause more brake pedal travel? The power assist made a sucking sound when I pulled off the vacuum line with the engine off after running for a minute, and the brakes work, but the pedal goes down further than it did with the calipers corroded and unable to slide and self center. I cleaned the calipers and greased them so they slide back and forth freely now. The old pads were worn unevenly, as in the outside pad was the only one masking contact with the disc, the inside pads had minimal wear/no wear at all indicating the caliper could not slide and self center to allow both pads to contact the disc. They were stuck good due to the car being driven very little by the previous owner, as the low mileage indicates.
