Question about Cadillac Brougham
Two things to check. If your car has a harmonic pulley on the crank shaft check that it is not slipping on the rubber insert and squealing. Second point is when there is no need for power steering ie straight ahead or idling there is no load on the pump so it will feel ok but as soon as you move the position of the steering wheel the valves close off and the pump comes under load. If the drive belt only drives the power pump and it broke then I would suspect a problem in the pump. Check that the belt is the correct size for the pulley groove as if it is too small the belt will run on the bottom of the pulley and slip, and squeal.

I need to know why you changed the power steering pump and the belt. It sounds like you had a problem and replaced the wrong component. You chould change whatever component is locked up behind the pulley and replace the belt. Let me know if this helps.

The belt is almost assuredly to tight and needs to be loosened just a hair. It is hard sometimes to get the tension just right. Try looseneing it a bit and hopefully that will help. I have had the same problem in the past.

It sounds like you have a broken serpentine belt tensioner. The tensioner should always be tight, it is spring loaded and you would have had to release the tension on it to have put the new belt on.Depending on what engine that is in yours, this could be an easy fix or a hard fix. The tensioner on a 2.2L is made into a large plate bracket that is attached to the front on the engine and several other items have to come off to replace it.The tensioner on the 3.1L v6 is smaller and has one bolt that holds it on.Either one is available at the local auto parts store.
Hope this helps
