So, this morning I fire up the silver ghost, hit the parking brake switch - and up comes an orange screen that says parking brake failure. Sure enough, there is none of the usual movement of the brake pedal that I normally get when i engage the parking brake. Now this is not a 'no ride' situation as I can always leave it in gear to prevent it rolling, but I hate that sort of thing. OK what to do now? I've never even taken the panels off this thing ! But I have restored my 95 wing so I'm not afraid of a wrench. Any videos that could help?

TIA
