I have just come back for a cup of tea after spending a frustrating 15 minutes attempting to put back the black brake cannister.
It came out OK after a bit of fiddling and would appear as if all that was required would be to simply push it back in. I am even doubting now which way round it fits, although I am 99.9% sure it is as per my picture. Is there a knack? does fairy liquid help?
Sorry to bother you all with such a triviality
Thanks Neil
