I don't know what else to call it, but the rear brake will make a noise and cause a vibration up through the handlebars. They are Avid Juicy 7's. I've replaced the pads several times, adjusted the caliper, replaced the rotor, replaced the skewer. Nothing changes it. I took the entire wheel off and put it on another bike and it did the same thing. When I put a different wheel on my bike, no problem. Put my wheel back on, there the problem is. It's a Mavic crossmax SL with the aero spokes, and I think the problem is in the wheel somehow. I've had it trued and the spokes tightened, and the bearings adjusted, still the same problem. I'm still convinced it is the wheel but I don't know what else to do. Any thoughts?
