Hi when changing brake fluid and bleeding should I be bleeding the clutch first or brakes ???

It doesn't matter, they're completely separate circuits with only the reservoir in common.

Great thanks thought it best to check in case thanks sepulchrave 👍

Ok so my buddy has managed to thread his one slider bolt into the hub so the hub thread needs retapping the bolt thread seems good any ideas on the thread size and pattern so I can try and find a tap to redo it please sorry my mate dont use internet hence why im asking about my car and his.

M9 x 1.25 if it's the 256mm disc set-up, I believe.

Various other repair options including helicoils, press-fit threaded inserts etc. all easily found on ebay.
