After having to remove the rear wheel to get the chrome sprocket cover on, I am thanking my decision to buy a service manual.
Without it, I reckon I would have been scratching my head over the brake calliper.
So if you are thinking about it - do it!! It will be the best money you ever spend!
I reckon they use air guns in the factory set to spec some how, can't see them pissing around with torque wrenchs like we do.
Just from what I have seen on utube etc.
My $0.02 worth.
