Drained off all the manky brown fluid today and then took out the fluid tank and removed all the hoses I could get to. The hoses had been leaking, especially where they connect to the tank. Replaced all the original fittings with new jubilee clips and cleaned all the gunk off the hoses. Filled it back up and after all the strange noises (glad I was warned about them) all was done. Steering felt much improved and didn't make noise at very low speed anymore, however fluid was now leaking from the banjo bolt even though every other previous leak was now fixed. The banjo bolt was fastened up very tightly to start with so I gave it another half turn to stop the leak. With a sharp snap, the banjo bolt head came clean off and all my nice new fluid began pouring out again 
Have left it dripping out into a bucket and will take a look later, am hoping the bolt will come out of the pump easily and won't have stripped the threads. Just my luck as I went for the more expensive Castrol Atf! Whilst fishing about in the bucket of fluid I came across the 2 washers from either side of the banjo bolt that must have come off without me noticing when I bled the fluid, doh! Luckily Alasdair answered the phone and had a spare bolt and washers, thank for your help, fingers crossed the threads aren't goosed!
