Thanks.

I would look elsewhere in the hydraulic power steering system for where the metal flakes originated.

I know GM decided to run the brakes and power steering vacumm all off of the power steering pump on some of their trucks. This could really be a big problem because if your power steering quit it would stop supplying your brakes with vacuum to stop the truck. In my experience I would check out the situation with the steering pump. Change it for a new one. Don't take any chances on smashing your truck.

u will need 2 special tool to remove and reinstall the powersteering pully
it must be removed to acess the bolts to replace the pump and a new pump dose not come with pully

Sounds to me like your power steering pump has gone bad. Being a vehicle with a hydro-boost brake system that would explain the power brake failure. Hydro-boost brake systems utilize pressurized power steering fluid to provide brake assist. In most lighter GVWR vehicles this function is performed by engine vacuum. There is a recall on certain Silverados and Sierras that addresses a faulty check ball in the booster, but your vehicle is affected by a steering issue as well. This would indicate to me that it is the pump. You can however check online to verify if your vehicle is affected by the recall. Hope this helps.
