Steering feels very delayed at times..Any ideas?

[MR.172 Cup]

For the past two weeks, my steering has felt very weird; at times it feels very delayed, then very light and then very heavy. I thought it may be that I have a warped brake disc. I have taken off my wheel and turnt the brake disc, when it gets to a certain point in the turn it becomes difficult to pull through and then after that little patch it goes back to normal.. Would this be a warped brake disc?

After doing some reading it sounds like it could be either the steering rack or the steering pump. When I had a look at the steering pump, the fluid was very low, as you do I topped it and thought the problem would be gone....BUT NO:nono:!

The worrying thing is the delayed steering, and when braking the steering feels pointless.

Has anyone on here had anything like this?

Any help would be greatly appreciated.

Thanks

When you say the fluid was low, was there any in the bottle neck? It should only have about 10mm in the neck and thats it, It shouldnt need topping up unless its got a leak somewhere!

I would probrably go to say it wont be long before the pump goes, assuming the aux belt is tight and turning the pump with the engine

there was only a little bit in there, then i topped it up. (might have topped it up a little too much)

Its weird because it sounds like theres a noise coming from the aux belt when the engine is running and when i turn the steering wheel either way when stationary. Had all the belts done in October/November 2011. could it be the aux belt? There isnt a leak from the pump because the power steering fluid has stayed at the same level and there arent any patches on my drive...
