Brake creaking...
I just started driving the box after a very busy 2 months. It's running well, but I noticed something new... If I really put my foot into the brake pedal at a stop light, well beyond what's needed to stop the car, I hear the calipers/pads creaking. It's loud too.
Not low on brake fluid, BTW. I checked that.
Ideas? Has anyone experienced this?

I don't understand this word "creaking". Squeal like a school bus? This I understand. Grinding like metal on metal? This I also understand.
How do your pads look?

Creaks like a rocking chair with a stressed wood leg...
I'm hearing the noise at the calipers, both sides.
Pads look good. Hmmmm.

I like to bed mine now then, it helps. My best guess is the anti squeal shims are causing the problem. How many miles on the rotors?
Also a air bubble in the brakes line can cause a pulsing effect.

I bet there's only 2500 miles on the rotors... But two DE's as well...

I see that you have over 100k on car. I would have taken the calipers off and removed the pistons, cleaned everything and reassembled with new parts...usually just seals. The pistons will not function as they should due to age and use...this is maintenance issue same any other part that needs it.

Sounds more like stress on some other suspension or steering component that stiffened up. Parts bolted together solid now moving or flexing a bit? Struts?

JCB, In the summer of 2011 when the car had 110k miles on it, I replaced the rotors and pads and thoroughly cleaned the rotors and even rebuilt one of the fronts with new seals. Now I have 114,500 miles on the car.
That's what makes this so odd to me. I wonder if anyone else has experienced this and figured out what caused it.
