I've been trying to chase down an annoying suspension chirp for well over a year and finally pinpointed the source. When I go over sharp bumps in the road, I get a chirp (literally sounds like a bird chip) from either front corner. The noise appears to be coming from the brakes since I was able to eliminate it by keeping light pressure on the brake pedal while test driving over roads that would cause the noise. I never had the issue prior to installing Axxis Deluxe brake pads. Has anyone else experienced issues with pads moving in the calipers and causing noise over bumps? Perhaps the pad spring on the Axxis pads doesn't hold them into the piston as tightly as the German pads. I only have about 15k miles on the Axxis pads but the noise is so annoying, I'm willing to switch back to OEM or Pagid pads if it will correct the problem.
