I have posi quiet ceramic pads with centric crossdrilled/slotted rotors. I put 4,000 miles on the pads and started to have squealing because I failed to apply anti-squeal grease.

So I took everything apart and applied the anti-squeal grease to every surface that I could find that had contact between the pad and the caliper including the front slide pins. I even applied it to the rear pins and clip.

5 days later the squealing is back but not as severe.

Any ideas?
