No need to be irritated
you just got a vacuum leak. You will need to inspect the tubing and fittings real good to find it. If you have a MightyVac just disconnect the small lines coming off of the vacuum supply line to the brake booster and start testing each circuit. You will probably find one of those fitting broken somewhere. You can purchase various sizes/types of vacuum fittings from AutoZone or Advance to make repairs as required.
