Never had it come off there, but did have it come of the gearbox end, which then resulted in the slave cylinder flying apart lol - tow'd of the M2 @ Belluve bridge on a cold saturday morning last yr - got it back re-fitted the cylinder took the whole pipe work out inc master & slave cylinderput new fluided in, pumped the slave cylinder a lot of times while keeping the master cylinder up high to clear the air (as there is no bleed nippples), put it all together and welded a U piece of metal onto the slave cylinder bracket to stop it happening again!
