I was going to do a trip to DC this spring/summer, but my father, who lives there, is adament about not wanting me to do it. He says that it worries him a lot, so I might skip it this year. (And do other foolish,dangerous things that he needn’t know about).
Not sure of the exact brake model number. I’m guessing, from the comments here, that it makes a difference?
My trick on getting my bb7’s adjusted was that I shoved an index card (actually a torn piece of a PBR case) in one side between the brake pad and rotor while I squeezed the brake lever and tightened the mounting bracket screws on the side that tended to lightly rub the rotors every time I tried to center it. Then removed the ‘index card’ and the brakes were better centered without scraping the rotors. Seemed to work for me.
Afterward, I adjusted the pad adjustment and cable tension for a better fit (and repeated the process at least once)
