I believe that the fork is flexing back and forth, struggling to remain straight from the power of the brakes, and THAT is the shudder. Does anyone agree with this diagnosis? Would a stiffer, or different, fork solve the shuddering?
I would also check to make sure that there is no play in the headset- I had shuddering that was eliminated by tightening the headset and cleaning the rims. (I have a carbon fork with aluminum steerer)
