@Sundayjumper,
I'm thinking about doing mine soon 116K(What was the mileage when you changed yours????)... Where did you pick up the specialty tool from and how much??? Did you change all four??? did you notice any improvident? if so to what degree...sorry to bombard you with questions but I just ordered rear brakes and debating doing this while I'm in there...
