Need some direction in trying to fix a 2007 chevy 2500 with 6.0. Power Steering went out while playing in snow in 4 wheel high. Replace pump with 3 different remans and now with a new ac delco. have power steering now but is hard to turn while setting still until rev motor then the power steering works, and when braking hard and turning the power steering doesnt work. when i changed the pump the first time there was alot of metallic flakes in the fluid. i have flushed the system several times, but still having problems.

Steering and Brakes are totally unrelated.

Steering wheel, steering pump, steering rack, wheels.

Brake pedal, brake servo, brake calipers and discs.

Take it to a garage.

if it has a 2.4 engine i would say your power steering pump shaft has broke.you will need to replace your pump.

It's either the pump or the belt or both. It could be as easy as checking the level of your power steering fluid but if this isn't the case then you can always just go and get a repair manual and start on one of these two issues. I highly doubt that your lines have deteriorated in the last 3 or 4 years.

the bearings have gone on your pump.Replace your pump before more damage can be done.

sounds like your hydro-vac went bad. this is located by your master cylinder inline. it uses your power steering pump to give boost to your brake system instead of a vacumn booster

There is a "pressure regulator" located in the pump just behind the high pressure line that directs high pressure fluid to the steering rack when you turn the steering wheel. It sounds like the regulator valve is sticking and not sending the high pressure fluid to the steering rack when you turn the wheel.
You can remove the pump and clean the valve, reinstall the pump and flush the steering system with fresh fluid or replace the pump and flush the system with new fluid.
Good luck.
