Default Re: Brake pedal can be pushed nearly completely down to the floor when standing

that isn't right... that noise you are hearing is your powersteering pump getting dragged down or the belt slipping.

if your not aware, your brakes are a hydroboost system which is run off your powersteering pump.

My service manuals are at the shop, but i think w/ the truck off- pump the brakes 4 times hard, hold the pedal down on the last pump and start the truck. I believe it should pump up, or feel the pedal push back on you.

My rigs been torn apart for 8 months under a massive rebuild otherwise I'd go out and confirm that for you.
