Front brake "humming" noise

About two months ago a got new brake pads - both front and back. After this I noticed a "humming" noise from the front brakes while stopping (rear brake is fine). Only thing I can compare the noise to is a metal wire vibrating in the wind. The vibration is also noticeable. Not severe, but can definitely feel it.
Before the brake pad replacement the brakes worked perfectly.
The braking action is still good, but not as good as it used to be. Takes a little longer, and a little more force to come to a stop.
I figured this was normal on new pads and it would go away as they broke in, but after two months and close to a thousand miles there has been no change.
What do you recommend I do?
Thanks for the help!

I would have the rotors turned ....resurfaced,or you could rough up the surface yourself and see if that helps,It's always a Good ideal to Prep the surface of any Brake Rotor, Bike or Cage before Installing New pads,Gives a Lot Better Bite,and smooth braking........IMHO

My front brakes have "hummed" since I picked her up from the dealer in august. Sounds like a whirring noise. They squeal a lot, too, if i'm not full on em.

Seems normal to me.

Did you replace your pads with OEM pads? or aftermarket pads such as SBK Carbone Lorraine, or EBC HH?

If aftermarket...it sounds like what I did in a rookie move awhile back. The sintered aftermarket pads consist of a material that is too "aggressive" for stock rotors!!! Started off with a humming...excessive noise in gerneral when I brake. Then some vibration when I braked......then, ultimately, over time, my brake lever started to pulse in my hand when I braked.

Turns out the pads were warping the stock rotors. I put on some Braking Wave rotors and everything was PERFECT.

I replaced my front pads with EDC HH about 4,000 miles ago. Two things I noticed were the "humming" and that the EDCs need some heat put into them before they start to bite as the factory pads did. Once they are up to running temperature though, they tend to have more initial bite and stronger stopping power. No sign of warped rotors.

I used EBC HH pads with the stock rotors for 15,000 miles without a problem. They don't hum so much as they go zzzzzzzzz when i'm hard on them. Now I've got ABM rotors on the front, and they don't zzz as loud now. I'd say it's normal.

Didn't say aftermarket pad material will DEFINITELY warp your rotors. But it happens...it's known, common info...it happens. If you do aggressive riding it can very well happen. It certainly did to me.

Not everyone buys a bike like this to commute, scoot around town, with an occassional ride through a canyon twisty. Some folks ride the bike to its limits and, sometimes, the stock parts aren't up to it. lol
