Well I have used shims to centre the disc.
I have removed the pads and cleaned everything.

But the buzz noise is still there.

I think I will just ride it for awhile and see if it goes away.
Though it is annoying.

If it's a  buzz and not a squeak or a scrape, it could be like the other s said and just the pads zinging across the disc. FWIW I have 3 bikes with brembos and they all make that zinging sound when the brakes squeezed.

My GT has a subtle "zit-zit-zit" sound which keeps pace with the front wheel rpms when in motion, that becomes a steady "zizzzzzzzzzz" sound when the front brake is on.  I assumed it comes from the pads skimming the disc (which they do all the time) as the vent holes pass through the pads, and the disc not running exactly true within a few thousanths. No issues or unusual wear evident after a few thousand miles, and less obvious with the stage 2 muffler on the bike, and/or after I've smoked a really good Arturo Fuentes cigar which tunes my tinnitus up enough to drown it out.

Yeh I think it is time to get over it and start enjoying the bike again. What you have explained Uncle Billy is pretty much what mine is doing. I'm happy with it now.

It would appear that the placement of shims for correct caliper alignment is initially dependent on the local supplier who, as I now understand it, assembles the front wheel onto the forks before sale.  In your case, it could be either the supplier or yourself as it only screeched after you had removed and replaced the wheel, suggesting "misplaced" shims.

I know the CGT has different brakes on it than my UCE G5 does so I can't comment about it.

That said, my G5's caliper does not have any shims on it.
The caliper is a self aligning unit that floats from side to side on guide pins so it can move sideways as the inner brake pad wears.

The Brimbo brakes on my BMW K-75 also were the floating design so again, there were no shims involved in positioning it.

Is there any Copper-Slip on the rear of the pads?  Mine were dry from the factory.

I have had a similar sound as Uncle Billy does on the front brakes my Continental GT. The sound would come and go depending how hard I used the front brakes. Easiest solution came by accident, I bought a new Scorpion Helmet, the brakes disk sound went away. Did not come back till I rode last week with my fav old Bell helmet.          Truth be told I missed the sounds of the ride that the Bell with worn out foam provided.

Thanks for all the comments on the buzz in my front brakes. I'm taking it to be checked by a bike Mechanic, to be sure all is ok. Will let you know what it turns out to be.

Took him no time at all to fix the noise.
He put a couple of groves in the pads and lightly sanded them.

Noise is no more.

Thanks Farmer.
Went for a nice long ride today without the annoying buz.
