If your brakes are in good shape and all hardware is in place and functioning properly there is a trick that I have used several times effectively.

If you haven't checked to make sure everything is ok then you absolutely need to check that first.

If everything checks out ok then you can take your cutoff tool and cut a groove down the middle of the pad itself. Some pads come with a groove already in them and your basically doing the same thing. The noise is from a vibration and changing the pad surface area by cutting into 2 pieces changes the frequency which changes the noise to something less audible if at all.

Do not cut into the metal surface. Only cut the "pad" portion.

depending on the material of the pad, it could be too brittle and will explode off the backing plate under hard braking after this mod. Been there. done that.

*IF* the pads are still good, you *can* take a wire brush to the rotors and remove teh glazing. Take the pads, and rub them on the concrete to remove the glazing on them. Apply brake quite. reinstall. Enjoy.

thanks guys, the brakes and rotors "should" be good, i just had em replaced less than 1500 miles ago. And its not like a metal on metal squeak, or "bad sounding" squeak, just a subtle high ptched one that happens just before my truck comes to a stop.

So should the wire brush trick work in this case if everything looks good? Also what is this brake quiet substance you speak of?

It's a paste that is applied to the rear of the pads. Get it at any parts store.

Don't you know your supposed to cut against the grain

Seriously though, I've never had that happen and I've never thought about it either. I guess I'll wear safety glasses next time just in case.

I think that stuff is just anti-seize that they put in a little packet and gave it a name so they can sell it for twice as much. I just use regular old anti-seize. Either way make sure you don't gob it on. You just need a light coat.
