Thanks, yes was probably jumping the gun a little bit, but it was because in the incident where I mashed the crossover, I landed really hard on the cylinder, so it would have been understandable if had started playing up. I forgot to mention in my earlier post that I had actually tried bleeding it with a syringe etc, as well as the bath bleed technique, but neither had been very succesful. Eventually discovered Saturday it was the new Hope crossover. Where the fittings on the end it are, they interanl diameter goes thick - thin - thick, and think this was causing it to hold little air bubbles in. Anyway, fixed it by using the syringe method and bath method combined, now makes an awesome brake! thanks again
