Yes thank you ,It was quite straight forward did not have to remove the pulley but I did have to go out and get hold of 2 24mm spanners which I didn't have. That's what took me so long the diy shops were closed when I needed them, It went back on a lot easier than it came off but bleeding the system took a good while. While it was off I noticed that one of the pipes was badly corroded so took it off cleaned it up treated and sprayed it. Its just today passed the dreaded mot so alls good.
