Shay Posted December 3, 2007 Report Share Posted December 3, 2007 Would the true of my wheel, effect my disk brake? I'm trying to identify the sound of a grinding noise, when giving the bike a clean I noticed that when I spin my front wheel, theres a not too noticeable grinding noise, but any grinding on moveable parts can't be great.Is this an effect of an untrued wheel, old brake pads or poor adjustment on the pads?ThanksShay.

gathsano Posted December 3, 2007 Report Share Posted December 3, 2007 (edited) Sounds like you have some sort of muck or grit between your disk pad and rotor. maybe take your pads out and check for any unwanted crap in there. the rim does not affect your rotor as it is fastened to your hub. Hope this helps.Gath. Edited December 3, 2007 by gathsano Quote Link to comment Share on other sites More sharing options...
Shay Posted December 3, 2007 Author Report Share Posted December 3, 2007 Alright, Thanks Gathsano I'll look into it. Quote Link to comment Share on other sites More sharing options...
Muel Posted December 3, 2007 Report Share Posted December 3, 2007 Wheel bearings?To check, remove the caliper so the disc and the caliper are not in contact, then spin the wheel. If the noise persists, it is probably your wheel bearings. Quote Link to comment Share on other sites More sharing options...

Fixed Pants™ Posted December 3, 2007 Report Share Posted December 3, 2007 Discs pretty much have to rub slightly for them to work well, they move such a small amount that it has to be really close to the pad. Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted December 3, 2007 Report Share Posted December 3, 2007 Discs pretty much have to rub slightly for them to work well, they move such a small amount that it has to be really close to the pad.Depending on what disc you have aswell, you may need the calliper to be offset, closer to a non moving pad than the other. IE on a BB7, the disc has to gently rub against the inside pad, as when you pull the brake, the outer pad is pushed inwards. Having it too far away from the inside pad causes the rotor to bend and give a really wank brake. Quote Link to comment Share on other sites More sharing options...
Guest Posted December 3, 2007 Report Share Posted December 3, 2007 was same with mine, my caliper just needed adjusting slightly....just have a play and you will work it out mate, its impossible for anyone to tell exactly what it is, as discs can make a grinding noise in loads of different places, so just have a play and mess around.and yeah as stated above, a wheel can be buckled by 10cm if it likes it wont affect a disc brake Quote Link to comment Share on other sites More sharing options...
