Hi Ant. The way i bled my hs33's was to get a large syringe and fill it with magura oil. To bleed it i left the little screw bolt slightly unscrewed to let all the air bubbles out. Once there was no more air bubbles coming out, just oil i screwed the cap back on and hey presto , one bled brake!, Once you have done it, I think you will find it isnt as hard as you thought it would be!
