I have developed a noise on light braking, at first it sounds as if the caliper shifts and smacks up against the caliper support or anti-rattle springs, then as the wheel continues to rotate there is that rythmic sound as if the rotor is warper and each time that spot comes around it loads the caliper and you can hear the rattle springs creaking. First off there is no vibration or pulsating when braking(which would usually indicate a warped rotor). It appears to be from the front and is noticeable all the time on light braking but is amplified while moving slowly through a drive thru etc. These are stock rotors and the stock ceramic pads. I forgot to bring the CRC brake stuff with me so we used silicone the last time the brakes were done. I don't see any evidence of the pds moving. Is it warped rotors or could the pins or guides be worn, and if the guides are worn does that mean replacing the caliper supports??
