Has anyone battled with a vibration issue with their brakes? It seems as though I've got a resonant frequency I need to break through. On sustained descents, the rotor begins to vibrate (it looks blurry) and the vibrations carry through the frame and HOWL loudly (not wet pad screeching, this is a brutal howl). I've changed pads, rotors, re-bled, re-centered.I have Zee calipers + metal pads + (1) 203 shimano RT66 and (1) jagwire 203mm rotor .
I found a shop in whistler that could actually give me an answer better than "well your rotor may not be true". They then explained this resonant frequency issue that is likely starting at the caliper. Their suggestion is to clean all metal mounting interfaces to the frame, consider adding an anti-seeze backing grease to the pads (like the stuff you use on cars) and look into adding a small weight to the caliper.
Has anyone else lived through this issue and have a solution to share? I'm curious about options and success rates.
