best way i find, get help with the wife/friend, remove cap of master cylinder and make sure you have a supply of brake/clutch fluid, slacken bleed screw of and get the wife or friend to press the pedalwhen the pedal is down tighten the bleed screw, then let the pedal return repeat again by undoing the nipple pressing the pedal 3 times should bleed the system, recheck the fluid level and top up with fluid,
