Yah, that's pretty gross. Disassemble and use more brake goo?
I had a set of squeally pads on my R65LS BMW. I loved it. Every one knew I slowing for a stop.
I think more pad goo made it go away. Maybe use some sand paper on the disks to be sure they are clean too?

I had the same issue with the last brake pads I put on my now defunct KLR650. Tried sanding the pad, tried angling the front of the pad so the tip would not grab as much, all to no avail. Could never figure out what the issue was. Could be the brake pad material itself.

I too would like an explanation as to the cause.

As far as brakes go, it's definitely a lower frequency sound. That suggest it is associated with the disc rotation and not just the pads vibrating. Check the bolts holding the discs on for proper tightness. It's easy to imagine that noise coming from a loose mounting point on the disc. Vibration between the disc and the hub/disc carrier.

AS GW said, it may just need time to bed-in, but if not, put a dial indicator on the disc and check for flatness.

Any visible abnormalities about the discs?

But my money's on a loose disc bolt.

Brembo pads had 10kkm time to bed in . No noticble improvment. I have checked the disk carier bolts. All tight. The rotors have some groves but after 38kkm i wouldnt expect them to be in any better shape.

It's a harmonic vibration.

Assuming the discs are in reasonable condition (don't worry about a few shallow grooves) remove the pads and rub them in a circular motion on a nice flat concrete surface to remove any surface contamination. Inspect the exposed parts of the pistons in the calliper and if necessary remove any crud with cleaner on a lightly soaked rag.

Then clean your OEM backing plate and apply the thinnest smear of Copper compound/grease to both sides of it. Attach it to a brake pad and repeat. Reassemble and test.

If this does not cure the problem, and your discs are in serviceable condition, you would then need to purchase calliper rebuild kits and disassemble the calliper/s to find out why one or more is not actuating smoothly. With used pads the pistons will extend further out of the callipers. If crud adhered to the exposed piston surface that crud might now be interfering with the smooth movement of the piston now deep within the calliper.

I have, in the past, had success with running a hacksaw across the pad to create a couple of grooves. This got rid of the squeal.

Did you try to e-mail Brembo on the issue and send the You Tube link?

noise

Had six Harleys in my mix of over 30 bikes in 50 years.Lesson learned on racket ...If all else fails more open pipes and tighter ear plugs. When its your bike it all ways seems worse :wink2: Good luck.

With a bike that young clean the brake discs with brake cleaner to ensure that there is no preservative etc on the disk. Then remove and clean the pads and reassemble with the merest smear of coppercoat etc on the back of the pad, and the back of the anti squeal "shims" #14 and #15.

Are you using OEM pads? If by 3 months old you mean a brand new bike, let the dealer sort this out under warranty. Brake squeal is NOT normal. If the bike is 3 months old to you, but say last year's model that you bought from a PO, then check the pad material. Some aftermarket pads will squeal on OEM rotors. This happens often in cars.
