Chevy C-5500 Kodiak Duramax potential safety issue!

Yes, the Hydroboost on my Seneca is working fine. It seemed as if it took more effort to stop but with the sound of the alarm going off, dash warning lights, the Hyroboost noise, the shut down engine and wrestling with the lack of power steering in heavy traffic, I could be wrong remembering the feel of the brakes. It was a relief to get it stopped quickly in a safe place!
