It must be possible to overhaul the servo. Has to be worth some surfing to find out.

If I could find out if the system could be changed over to say normal brake like on everything else....lever, master cylinder, lines, calipers.......then I'd do that....but I must admit it's like playing Russian roulette lol just a waiting game....I was reading about someone in the Pyrenees and coming down a mountain section of road fully loaded the servo failed.....is there a roughish mileage figure of when they fail.....or is it when they do they do....lol I realise that all bikes have their problems.....
