I tried pumping the rear brakes today as I rode to work and it doesn't seem to make a difference. So I would say a diagnosis (sorry once a doctor always a doctor) would not be air in the lines. So looks like I should just get some new rear pads. I have to agree with Ian, and I'll wait until the fronts feel bad until I replace those. Explain to me "scuff up" the rotors. What is this process?? Thanks guys.
