There is no way vacuum can cause a caliper to stick. I have read an awful lot of posts over the past six or seven years, and have never read that one. The only thing that can cause a caliper to hold is either your foot on the pedal, then assisted by vacuum, and a situation where the brake fluid can not get back to the master cylinder due to a blockage in the hose. There is no vacuum connection to the brake system except at the vacuum unit behind the master cylinder and then you get assistance as you press the brake pedal.
