I m starting to get a vabration sound form my front brakes somone told me it might be a rough spot on my rotors ... is it sandable or should I just replace em? it only viabrates on a ceratin spot on my rotor.
it viabrate only when IM about to stop in other words when im going slow and engaging the brakes... can anyone help?
20,000 I would say you need to replace them. But what you are describing also sounds like a glazed spot on your rotor, it generally skips over at speed and you may not feel it, but as you slow down to parking lot speed then you do.
You should check your rotors periodically (especially after hard riding days) for any shinny spots on the rotors. Once you see them take a 100-200 grit sand paper and sand the rotors. You can put the bike on rear and front stand, grip rotor with the sand paper on both sides and spin the wheel.
I checked its well over 5MM and i wiggles the rottor around a bit all around all the pivot points if you can call it that I did a little test ride in the parkig lost so far the vabration sound and feel is gone...
