I don't see how, unless I got bad from stock bushings. I rebuilt the whole caliper, bushings and all, and I got new contol arm bushings from BMP. The shake is 90% in the pedal. Once-in-a-while I feel it in the steering wheel, but most of the time it's in the pedal, and when I reapply pressure, or put more pressure on it, it's fine, nice and firm, no shake.
