I recently replaced my front pads (Hawk HPS), rotors, and all brake hardware including slide pins. I flushed the fluid front and back. I bled all the calipers, and the master cylinder. I used brake quiet on the back of the pads, and greased the heck out of the slide pins, and the contact points of the brake hardware. I properly bedded the pads in. The car stops on a dime. I have no performance issues at all. My problem is that both of my front calipers are creaking like the front door of a haunted house. This started when I was flushing the fluid, and my son was pumping the pedal while I worked the bleed screws. I took it all back apart, and regreased everything. I don't know if my calipers need to be replaced or what. They work great so I hesitate to replace them. Maybe I should grease the back of the inboard pad instead of using brake quiet. Any suggestions?
