Power Steering & Brakes screaming

This may be dumb but here goes.

Every time I get on my truck hard my power steering pump and brakes scream at me. My brakes vibrate/pulse and hum, and my power steering whines like a baby and gets louder when I step on the accelerator. This ONLY happens when I get on it hard and only lasts for a few minutes. I've asked a few mechanics around here and no one knows what's wrong. My fluids are fine, but this has been getting progressively worse. Maybe I need a new pump and brake thing? Help.

When you say fluids are fine, are you saying that they (PS fluid) are/is full or new/recent? Power steering fluid degrades over time, especially on a Hydro-Boost vehicle. Ford has had a problem with noisy pumps in the past too. As someone mentioned in the other thread where this was posted, check you belt and tensioner. If that seems good I vote for flushing the power steering fluid and see what happens. A couple of quarts of synthetic fluid is cheaper than throwing parts at it.

Agreed^^^ it could help to just flush the system 7.3 but the same. if that doesn't help, idler pulls and or pump are what I'd look at next.

Thank you guys! I just had the engine rebuilt in May so I'd assume it's fresh fluids in there, but you never know. Would the pump itself going bad effect the brakes like it is? An if the pump is going bad...why does it only happen when I stomp on it?

I would definitely check belt tension

fluid condition , specially fill level, belt condition then I would be considering a pump if it was mine

sounds like the pump is screaming and since it's the hydraulic pump for your brakes that is why you feel it there also
