oldmankirby Posted April 25, 2017 Report Share Posted April 25, 2017 I took my wife's 2012 Ford Edge in for the Power Brake Booster replacement. When she picked it up she noticed a grinding noise. I drove the car and also heard the grinding noise. The noise is only heard when driving at low speeds with light braking. It sounded like it needed new pads. I took it to a Ford Dealer and they could find nothing wrong nor did they hear the noise. This was because it was raining and you can't hear the noise when it is raining. But they said the pads and rotors looked fine. The noise continued, so I ordered new pads and rotors for both front and rear. After I replaced them this weekend the noise still persists. Upon closer listening it is only coming from the rear, but on both sides. I checked the caliper pin boots and none were ripped and the caliper floated like it should. Any ideas? It is back at the dealer now, and while they can hear the noise they say everything looks fine. Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted April 25, 2017 Report Share Posted April 25, 2017 Could be a brake dust shield that is bent, or rocks caught in there, but why it stops when it is raining, IDK. You said the caliper slide pins were serviced? Quote Link to comment Share on other sites More sharing options...
oldmankirby Posted April 25, 2017 Author Report Share Posted April 25, 2017 No bend in dust shield, nor rocks. I replaced all the rotors and pads as well as cleaned out any dirt, rust or rocks. Just heard back from dealership, they don't know what the issue is, but are sure it isn't their fault......... Their suggestion was to replace the pads, again.

Are your low frequency noise dampers still attached to the rear brakes? 1 Quote Link to comment Share on other sites More sharing options...
oldmankirby Posted April 26, 2017 Author Report Share Posted April 26, 2017 Are your low frequency noise dampers still attached to the rear brakes? Yes they are, however can they go bad? Are they just a weight attached to the pin? Quote Link to comment Share on other sites More sharing options...

macbwt Posted April 27, 2017 Report Share Posted April 27, 2017 If it is FWD jack it up and spin the wheels. Without hearing it and with new brakes (breaks for AKirby AkA Old man) I would not be able to help much on this one. 1 Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted April 27, 2017 Report Share Posted April 27, 2017 Btw what rotors and pads did you put on. Not that i think they are the source of the noise. 1 Quote Link to comment Share on other sites More sharing options...
oldmankirby Posted April 28, 2017 Author Report Share Posted April 28, 2017 Btw what rotors and pads did you put on. Not that i think they are the source of the noise. They were AC Delco Ceramic pads and AC Delco Rotors. 2 Quote Link to comment Share on other sites More sharing options...
macbwt Posted April 29, 2017 Report Share Posted April 29, 2017 Just kidding you. You sure the pads were not installed backwards/flipped with the metal against the rotors. 1 Quote Link to comment Share on other sites More sharing options...
Melissapickles Posted July 13, 2023 Report Share Posted July 13, 2023 Did you ever figure out what was wrong with your car? I am having the same exact thing happen and I thought maybe it could be the break booster valve. Quote Link to comment Share on other sites More sharing options...
