If I pull over I can wait or just got to the Brake booster and release the vacuum and it will release. Any ideas will help.

Codes coming up when scanned

The reason Chevy brakes lock up are that the calipers are rusty.
Disconnecting the ABS plug from the master cylinder will disable the ABS to the wheels and eliminate one possible reason.
After a while, you'll see it's always rusted calipers and pins first.
