Arggg, that annoying brake noise

[-DSM2NR-]

There's this weird noise coming from my passanger side brakes. There's no noise until the car warms up and the noise goes away when I step onto the brake pedal.

What's wrong? I doubt it's the brake pads since the noise goes AWAY when I press the brake pedal all the way in.

The caliper could be seizing up. The 1g's are notorious for it, I'm not so sure about the 2g's though. What exactly does it sound like?

 

[-DSM2NR-]

It sounds exactly like worn pads. Perhaps spraying the brakes with some fluid or spray will get rid of the noise?

Like I said before, the noise appears only after the brakes have warmed up (10mins after startup or so...)

Could blow some brake cleaner on the rotors and pad. Check that the caliper slide is griessed (under the rubber boots). Also while your at it check that the bolts holding the calipers on isn't loose and the brake lines aren't rubbing or in contact with the tire. If anything else... possibly consider taking the pads off and inspecting them for weird wair. If still nothing... consider delving into the wheel bearings.

mmmkay

After driving a bit, stop and feel your wheels. Is one significantly warmer than the other side? If so, the brakes on the warm side may be dragging as suggested by SinaiTSi.

Another thing that can happen is that the clips that are holding the pads, get worned up and that the pads are just rattling in there. It happened to me on a 1G, in the rears, but I'm not sure if it happens on 2G. So, just check if the brake pads are rattling or being loose in there. Good luck!

Any luck?

not yet. The first thing I'll do is check my pads. Hopefully that's what's causing the problem. I already tried adding some "de-squeek" spray but it didn't help at all.

You should take the pads out and see if the calipers are siezed or not, like mentioned above. This is what I did:

Take off the bottom bolt holding the caliper on and inspect it for grease. It should have grease on it and move in and out of the caliper easily.

Now try to move the caliper back and forth on the top bolt...it should move in and out easily and have grease on it too.

My calipers siezed and were noisy, mostly when cold. Also, get some disk brake caliper grease and put some on the ends of the brake pad backings where the springs hold them in. Don't get ANY grease on the pad surface or rotor.
