My 92 Si brake pedal keeps popping randomly a lot when i step on the brakes. Sometimes when i touch the pedal light and sometimes when i stomp the brakes hard. Sometimes it will do it right when i start the car up and have my foot on the brake it kinda pops at me. It doesnt seem like the pop that the abs gives either. Anyone else have this problem or know what it could be? I have new pads front and rear and new rotors. I'm stumped on this one. If anyone has any ideas please chime in.

 

bump anyone?
