I read that about the brake cylinder in the service book just after buying mine new. Apart from the 600 mile service I won't be entertaining dealers ever. As for the need to replace the brake internals, why would they need it was my view, I certainly wont be doing it unless I have a master cylinder issue which would mean I would do it straight away in any case.

I can't work out why they have picked on this as a service replacement item, unless its a revenu generation for the dealer network. I wonder how many service kits to do this are bought by the dealers? Why don't they have us rip the engine apart and change all the oil seals whilst its having the brake seals replaced (tongue in cheek).
