A few months ago my front brakes started squaking as I came to a stop. I decided to upgrade so I bought some EBC FA347HH pads. I put them on and soon discovered it sounded like I was surrounded by a ton of angry bugs every time I hit the brakes.
I opened a case with EBC and they told me to put 500 miles on the pads to see if they break in. I did that and they didn't get any better.
EBC sent me a new set of pads and I just put them on. I took it for a 5 mile ride and they didn't sound much better.
Could something be wrong with my rotors? They don't seem grooved to badly. Or, is that just the nature of this specific pad? Is there a quieter pad?
Here's a video I took to show the noise. The video actually makes it sound worse. It sounds like metal on metal. Or it could really sound like that and my helmet buffers out some of the noise! https://goo.gl/photos/XPgvzFvaRNYFpczs8
They should not do that no matter the brand. I have EBC-HH and they are silent. Did you transfer the perforated backing plate from the originals to the new ones? Did you sandpaper the new pads? Did you clean the discs and go over them with fine sandpaper or Scotchbrite? Did you put them through a break-in regimen? If your answer to any of those questions is no, do that and report back.
Chamfer all the edges. I did that and it helped a bit but did not totally eliminate the noise. I ended up going to kevlar pads and it's still there but noticeably less. Mine is so bad that people on the sidewalk look when I come to a stop at a red light. The relieved pressure is exerting too much pressure on the pad/ rotor. Two trips to the dealer under warranty yielded nothing in the way of a fix.
In my case something is sticking in the pistons that I had hoped would be gone by now after a suitable break-in period. Nope. After a ride at highway speeds my front disk is hot enough you can leave your fingerprints on them. Rear is fine.
There is no pre-assembled maintenance kit for the Brembo's and I don't have access to the resources to see if another kit or parts of kits will work. Next winter I'll do an aggressive polish/hone on them and hopefully free them up a bit.

Living on a dirt road my calipers need cleaning occasionally.
Every bike I own the calipers are a little different but sooner or later some the pistons hang up and they need cleaning.
You'll have to modify it just a touch to work with your bike but you don't need a rebuild kit to get your calipers working like new. One of our bikes needs it done about every other year.
I usually just clean up the rotor with brake cleaner and swap pads. I've never used sandpaper on either. I didn't realize there was a backing plate, but now that i look at the old pads, I see it.
Guess EBC are a bit more noisy then stock, but MUCH BETTER thus SAFER, my EBC front pads didn't last very long
so I just ordered Lyndell Gold from WD, hope they last a tad longer, in any case I ordered 2 set to be sure ha ha ... shipping is expensive buy the way ...
first lay coarse sand paper on flat surface and run pads over the sandpaper a few times shortens the break in period. That's all it does.
Getting some brake clean and old tooth brush and clean up the piston area really good so they can expand with no hang up. The back ledge of caliper wear the pads rest needs to be cleaned and free of burrs and nicks for smooth travel. The hole in the brake pad that the pin slides trew I countersink both sides so pads will slide easy. Now the pin has to be clean and very smooth. If it's not smooth pads will hang up and wear uneven. If you pull old pads you should see a flat surface. If not look for something hanging up the pad.
In some case like excess noise might be to hard of rotor. The only thing you can do is get another rotor. Also to little hand pressure on brake can cause the noise
As far as that video goes I couldn't hear any thing out of the normal but then there was a lot of motor noise
buy a good countersink drill bit and countersink all the rotor holes on both sides could cut down on the noise. I think doing this makes pads last longer
My EBC's don't make any noise. I like Lyndalls (but pricey) and they did make a noise.
I'm surprised no one has suggested the ol' rubber mallet. Brake dust will build up in the floating rotor bolts and cause the rotor not to move. LIGHTLY tap the bolts with rubber mallet and it frees the rotor up to float again. Might cure the noise......
It's an old trick a bunch of us "old time" Vic owners learned a while back.
Well, I went ahead and transferred the backing plates over to the new pads, sanded them a little and put a bevel on the edges. I de-glazed the rotor and wiped it down with brake cleaner.
I took it for a ride and it made the same damned noise. I'm pretty sure these EBC pads are just made of rock.
I just put the original pads back in. If they start to squawk again I'll try a different brand!
Been there and done that a few times myself and have had same results .
