It seems to be never ending now.. at 57k, parts breaking/worn... The latest is the rear brake master cyclinder resevoir cover, it turned into a rich tea biscuit and broke in half. Christ the hassle I had getting it off.. And the 2 small screws didn't 'round' as you would expect but they turned the nuts at the bottom of the resevoir in the plastic where they were moulded in. I've Dremmeled my way in to the plastic to get a hold of the (6mm) nuts, but it's no go. And have come to the conclusion that the resevoir is bin material. And I bought a new lid for it too, cost me 10 quid. Bugger. I'm just gonna affix a large bore clear plastic tube with a stopper on the top to the master cylinder and be done with it, that'll do.
