Finally got another rotor of a different brand and the vibration has gone. Seems it was two faulty rotors (from the same manufacturer). Will be interesting to see what they say... <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_smile.gif" title=":-)" class="bb_smilies" alt=""/> </p> http://singletrackworld.com/forum/topic/help-got-brake-wot-dont-work#post-3592476 Thu, 15 Mar 2012 15:40:10 +0000 retro83 3592476@http://singletrackworld.com/forum/ <p><blockquote>mrjmt - Member</p> <p>Wonder if the rotor has a thick spot? do you have access to an accurate measuring device? digital calipers?

S'pose it'd only take a fraction of a mm to cause this. </p> http://singletrackworld.com/forum/topic/help-got-brake-wot-dont-work#post-3592467 Thu, 15 Mar 2012 15:37:23 +0000 mrjmt 3592467@http://singletrackworld.com/forum/ <p>Wonder if the rotor has a thick spot? do you have access to an accurate measuring device? digital calipers?

Feels like going from 50% to 100% braking at about once per rotation.</p> <p><blockquote>Dibbs - Member</p> <p>The disc may be running off center, try loosening the disc bolts and then re-tighten while twisting the disc clockwise to centralize on the bolts. </blockquote></p> <p>Cheers, I'll try this again. Wondered if the lip which is broken is normally supposed to centre the rotor, hence it being out of alignment vertically.</p> <p><blockquote>honourablegeorge - Member</p> <p>If there's a couple of mm of play in your rotor, then that's most likely the issue. Could your hub shell be cracked? </blockquote></p> <p>not play, it's solid, but you can see it moving relative to the caliper when you spin the wheel <img src="http://singletrackworld.com/forum/my-plugins/bbcode-buttons/default/icon_question.gif" title=":?:" class="bb_smilies" alt=""/> </p> <p><blockquote>wwaswas - Member</p> <p>tbh, if the rotors not actually round when mounted then I'd get that sorted before looking any further? </blockquote></p> <p>Yes will try to, but I think the (half broken) broken lip it's resting against will prevent it from being moved. </p> http://singletrackworld.com/forum/topic/help-got-brake-wot-dont-work#post-3592426 Thu, 15 Mar 2012 15:21:53 +0000 motivforz 3592426@http://singletrackworld.com/forum/ <p>Are they ashima rotors?
