PS pump is a commen prob on saxos pain in the ass lol mine failed whilst goin around a huge ass roundabout lol was tug of war i tell you i got home and after some rather cheese but awesome advice.
i hit the pump with a hammer and hte dam thing works better now then it originally did lol
think it was crap that built up in it i also topped my fluid up to

you should be able to get a PS pump from a scrapyard for way cheaper but remember you pay for what you get at those places.
so its best for you to buy one brand new then you know if its faulty you can send it back
