help: lost power steering and power brakes?

[Mdnewbie]

I have a 2004 Tahoe Z71 and was doing a u-turn but when I came out of the turn, I no longer had power steering or power braes. Had to push the brake pedal all the way to the floor to get the truck to stop. Got home by driving 20 mph max.

What could have happened to cause both to go out at the same time?
Fluid levels are good. Coould trning the wheel too sharply cause this?
Also, no fluid leaks under truck at all.

Any suggestions will be greatly appreciated. I'm at a lost.

Thanks. :shrug:

Check all your hoses and vacuum lines I bet one popped off or has a hole in it

is your battery light on? Any Lights on in the Dash? I had a pulley come off an Explorer once and lost Power Steering, Power Brakes and it started to overheat. The Belt may not be running the pump anymore.
