Woohoo, my replacement master cylinder came yesterday and I managed a bit of time in the garage tonight to get them swapped over.

All I have to do now is bleed them again and I'm back on the road in time for the Quantum Owners Club practice day up at Curborough next weekend

Put some bleed nipples in the master cylinder first to get air free fluid before attaching the pipes.
Just eliminates the master cylinder from ant bleed problems early on.
Ask me how I know.

Is good idea!

I have managed to get the front circuit flowing, but not clear yet. I need another set of hands for the back ones so that will have to wait for later in the week.

Cheers!
