Hi all
My MTB has developed a very high-pitched whining/whistling/ringing noise from the front wheel in the last few rides. Like that noise a wine glass makes when you run your finger round the top. It happens at all speeds, even just pushing it along. However, if I apply the brakes a little, but not enough to stop the wheel, the noise stops. Then release the brake, it stays quiet for a few seconds and then the noise slowly builds back up
Anyone experienced this? I'm going to investigate tonight, but if anyone had any pointers in advance it may save some time later.
Spec is M666 SLX brakes and matching 203mm rotor, Hope Pro 2 hub, Pikes with the 15mm axle if any of that helps
Thanks in advance,
Wilko
Check to see if my wife stuck in your spokes
Heh heh. Excellent!
Had this happen a few times. In every instance it was due to the pad spring, just touching the rotor. Suspect, again, in every case, that it had been due to something stuck, albeit briefly in the calliper, mis shaping the spring. Worth a look !
Is a 26" wheel in a 650b frame? Is it hora?
Run over Ariana Grande?
Tea spat out at bruneep's contribution 😆
My guess is it's your brakes HTH 😐
It's probably a dry seal squealing. A tiny drop of oil on the seals will cure it if it is. Seen it hundreds of times 🙂
Edit
Just re read the OP. I'm talking about bearing seals and I might have missed the point.
Squirrel? Little shites are everywhere around here
Thanks for the pointers peeps and also the comedy suggestions 😀
It's most likely the brake pads, or springs rubbing on the disk.
If it's the pad, then just pulling the lever a shade can stop the pad vibrating (which is the noise) on the disk. If it's the spring then it would likely not stop 'whinning' even after the lever is pulled. Either way, look to the pads first.
Well, anyone on tenterhooks wondering what could possibly be the cause of this intriguing and baffling mystery can rest easy now. One of the pads was rubbing very lightly on the disc, causing it to whine like bruneeps wife. A simple re-alignment of the caliper/discs sorted it. Thanks all 🙂
You might want to lube the pistons a bit while you're at it. Shimano's can get a sticky piston. Normally you can cure it byremoving the pads and dripping some mineral oil around the pistons, carefully working them in and out and dripping a bit more oil as you go, should rinse quite a bit of crap out and hopefully make them a little smoother.
Make sure you give them a good wipe after you've finished.
