Thanks for following up and giving the part number!
Here's a test if you want to be sure your booster is working.
1 - With the engine off press on the brake pedal a few times to insure there is no vacuum left in the system.
2 - With medium leg pressure step on the brake pedal and start the engine.
3 - If the booster is working you'll feel the brake pedal fade towards the floor as the engine builds vacuum.
