A little story. I put BB7s on the SS and soon enough ended up with a nasty pulse under braking in each wheel. It was bad enough to lock the wheel if it was unweighted enough. No fun when precision braking was required.
I tried different things, pad sanding, rotor sanding with emery cloth, the rotor seemed quite true to me...maybe a slight run out in the rear, but the front was dead on.
Swapped to G3 Cleansweeps and new, organic pads. Much smoother overall, but the pulse remains. HUH? So I figured it had to be one of two things...the rotors were still out of true, the hubs were not faced true, or there was some vertical hop to the rotors.
I made sure the rotors were as true as possible. I can barely see light between the pads and rotors and there is some contact as I spin, but wow...that is getting down to such fine adjustments that I am surprised I can even feel what I am seeing.
I wonder if the BB7s, since they have that one, fixed pad, if they are more sensitive to rotor trueness (trueness???)
Very odd. I bedded the pads in carefully down a 8 mile downhill on pavement. They pulsed at the beginning and at the end...no difference. By now after about 6 or 8 caliper alignments, I am pretty satisfied they are square to the rotor, but if not, I would not know how to do it a better way.
