Scott Just because the reservoir is higher than the caliper doesn't mean the pads can't push the pistons back. The mass of the pad plus the mass of the two pistons under side g's is a lot more than gravitational pressure of the reservoir fluid (unless you have a 2 gallon container up there
) . I think the fixed caliper design in conjunction with the "wobble" from the hub flex/bearing play is the culprit, and any of the suggested fixes are bandaids. But then, bandaids often do work. And it's all about having a consistant pedal at 150+ at the #2 marker, isn't it.
