Brake noise while driving/backing up
Hi guys,
I have a stock 2007 base TL. I noticed a squealing noise that sounds like it’s coming from the front brakes only while driving (no noise when pressing the brakes). It also sounds like a squeal coming from the rear when I back up. Started about a week ago and hasn’t gone away. I went to my mechanic to check the pads/rotors and they said they were fine, both looked good. The only reason he offered was possibly brake dust buildup/change in weather. Should I try a brake cleaner? Or get another opinion? Brakes feel fine, no shake or anything out of the ordinary…it’s just terribly annoying and sounds like it’s getting worse.
Thanks!

If there's no metal on metal (worn pads down to metal grinding on metal rotors) then the noise is vibrations of the pads most often. The best solution I've found for reducing or eliminating brake noise is conservative amounts of brake grease to certain areas on the calipers, clips and most important brake pads.
1) The guide tabs, back of the brake pad, and if there is a retainer clip that presses against the pad that area need very small amounts of brake grease.
2) Likewise the caliper hanger where the pads ride in the slot, should be cleaned with a wire brush and a very small amount of brake grease applied there.
3) Any clips or guide pins also get brake grease.
4) The only area to apply alot of brake grease are on the sliding guide pins for the caliper to the caliper hanger/frame. These pins typically have a rubber dust boot over them
5) NEVER apply brake grease to anywhere on the rotor or the brake pad material.
6) Again on the exposed area's where the brake grease is applied, use sparing amounts.
StaLube from CRC I've used for decades is excellent brake grease. Do not use regular grease as it will melt with the high temperature environment of brake usage.
