Ok guys, I have this weird sound when I hit the brake. Sounds like a piston from the caliper is broken, or something like that, because it sounds like two metals hit. The weird thing is that the sound is late from when I hit the pedal. Some seconds later (with the foot still on the pedal) there's the sound.
I would apreciate some light on this situation. Oh, and the calipers are the originals. Thanks.

 

I had a very similar sound with my front driver's side caliper. I would recommend checking your caliper studs to see that they are properly tightened. My sound was a single "bang" that only occurred about 75% into my stops. I'm still troubleshooting.

 

Thanks man apreciate it!!!
