500 Brake pad options wanted.

You can change just one pad if you are sure they are the same make and grade

I used EBC pads in an attempt to stop the squeal from my front brake and it didn’t help. But I saw a recent post talking about chamfering the edges of the pads which I did and squeal seems to have gone. I have no idea why this happens!!!!

I have posted previously that almost all modern cars have chamfered brake pads - I know it works but have no idea why - it's been my experience that the harder the pad the worse the squeal.
Edited Google search says:-
Chamfers can control how the edge of the pad interacts with the disc and can help prevent noise. Chamfers do this by making sure the largest possible edge of the pad makes contact with the discs.

Yes, they are.
@Ted. Here's a hypothesis to be tested. On my Koga Miyata Terraliner, a hybrid bicycle, I used to fit the V-brakes thus, that the front part would contact the rim first. I did this on purpose, after I had learned in a bicycle workshop that you could cure screeching by the opposite, by having their rear parts contact the rim first. The opposite would make your brakes screech and they did like hell. Worked great in alarming pedestrians to get out of the way. I admit I was childish. :-[
Now on our bikes the inner pad can wiggle somewhat and personally I don't think that one is the culprit. But... could sqealing eventually be cured by seeing to it, that of the outer pad - the one activated by the piston - the rear part contacts the disk first by a millisecond?
florence:
In order to transfer kinetic energy and thus slow down the bike, the pads must apply friction creating heat and, in the case of my bike, sound energy in the form of a loud squeaking. My brakes need all the help they can get so I'm happy with the squeaking. It tells me some energy transfer is taking place ;D

Anecdotal update:-
I sent a message to the supplier of my Brembo Pads as they came without the nylon type pad asking if they could supply one.
They say they are sending me a complete replacement set as the nylon pad should have been in the package.
It will be interesting to see what they actually send me.
