Default WTF is this noise? Could it be a bad wheel bearing at 1500 miles!?

I was parking my bike tonight and this is the noise I heard.....could this mean a bad wheel bearing....something in the brakes? Any help is appreciated!

Sounds like a slight high frequency vibration of the brake rotor induced by brake pad/rotor contact. Nothing to worry about.

No way could it be a bearing. The short distance you rolled the bike in the video would translate to very little bearing rotation, and certainly not enough rotation to cause that noise.

I had my wife sit on it and roll it forward and I grabbed the rotor and it stopped. It is the brakes...is it something that can be adjusted? If so....how? Or is it gonna go away? I only rode it for 3 blocks when I parked it.

It's really nothing to worry about. Get rolling 2 or 3 miles an hour and it probably goes away... Right?

It's simply that when the brake pad contacts the rotor at such a low rate of speed it induces a slight chatter of the pad. The chatter of the pad translates to the rotor and causes the rotor to vibrate at just the right frequency to create the sound your hearing . It will have no effect on brake function in normal operation.

I hate to say it's "normal", that word seems to be sacrilegous around here, but nevertheless it is quite common.

You could try some anti-sqeal compound between the pad and caliper piston, or check that the caliper piston is not binding, or check the rotor for runout, but really, it's just not worth the effort in my honest opinion.

I just took it for a 5 mile ride and got it up to 55 parked it, and it didn't make the noise. The bike only has 1500 miles on it. I took it about 3-4 blocks, I ate dinner and rode 3-4 blocks back....when I was parking it, I noticed the noise.

Ride it, use your brake a couple of times and it will probably go away.

You can also file the leading edges of the brake pads at an angle.

I developed a whine at around 50K, but you could not hear it when moving it in the garage. I replaced rear wheel bearings at 61K, that fixed it.

You are hearing normal noises (I think). The brake pads are always just bearly touching the rotors.

The metallic composite brake pads will make noises like that from time to time. I believe it even states this in my 2009 owners manual, but I have to go back and check. It is, as other posters said, nothing to worry about. Mine does it on occasion and goes away as the miles add up.

I noticed that my Heritage did that a few weeks ago, so I traded the damn thing in for a 2012 Road King.
