adamjosiah Posted November 19, 2011 Report Share Posted November 19, 2011 So I have a Ford Edge AWD SEL '07, which I bought in the summer so I had no indication of this when I first got it. However as the weather got increasingly colder, I started to notice it. Basically, whenever it's been sitting in the cold or the rain for a couple hours or more, when I back-up (and occasionally when I'm braking forward) the breaks squeal, sometimes quite loudly. Almost instantly after I start driving the brakes stop squealing completely, forward or backward, and won't start again until the vehicle has been sitting for a while. But it is quite annoying when I back out of the drive way in the morning, or out of a parking spot and I hear the horrible squealing again. As for the functioning of the breaks, there's no problems at all. There nice and firm and reasonably sensitive. Any ideas what might cause this? Is there a brake pad coating of some kind that can solve this? Quote Link to comment Share on other sites More sharing options...
mrdave Posted November 19, 2011 Report Share Posted November 19, 2011 As your car sits, especially when it's damp or raining outside, a very thin layer of corrosion will form on your rotors. The squealing you hear is just the pads cleaning off the rotors' braking surface. Once the layer of corrosion is gone it stops squealing. This is completely normal behavior.

It is wiped of by the brake pads the first one or two times you apply the brakes (figured I would save you the trouble this time, Allen ). Completely normal and nothing that can or should be done about it. Good luck. :beerchug: Edited November 20, 2011 by bbf2530 Quote Link to comment Share on other sites More sharing options...
adamjosiah Posted November 20, 2011 Author Report Share Posted November 20, 2011 I appreciate the answers, and I'm glad to hear its normal. I guess I'm just curious why it happens, after all you don't hear vehicles squealing all over the place as they back out of parking spots :-P Quote Link to comment Share on other sites More sharing options...

DXXL Posted November 29, 2011 Report Share Posted November 29, 2011 I just started hearing the "noise" over the weekend. Short of changing the rotors this is something I have to live with from this vehicle? '08 Edge Limited AWD Quote Link to comment Share on other sites More sharing options...

Sometimes the noise comes from the back of the pad where the piston contacts it - you can remove the pads and apply squeal stop to the back of the pads and reinstall them - may or may not help.

What they might be hearing, depending on mileage on the vehicle, is the brake pad warning squeal--- caused by pads that have worn down to the "replace" limit--- If the noise goes away when applying the brakes, the wear indicators are the problem. May be time to replace pads! Quote Link to comment Share on other sites More sharing options...

4x4 Posted February 11, 2014 Report Share Posted February 11, 2014 Mine is doing this now, was it just decided it was during cold and wet times it makes this noise? When I drive it for a while or after it warms up it does not make it. Quote Link to comment Share on other sites More sharing options...

When I drive it for a while or after it warms up it does not make it. That is correct. Very common problem on the Edge. Also, check your brake fluid level in the reservoir. If it is substantially less than the full (MAX) mark, your brakes are also substantially worn out. Quote Link to comment Share on other sites More sharing options...
4x4 Posted February 11, 2014 Report Share Posted February 11, 2014 Ok thanks. My MKX is an 07 but only has 70000 miles on it so don't think my brakes are bad. I will check the reservoir just to double check. Quote Link to comment Share on other sites More sharing options...
akirby Posted February 11, 2014 Report Share Posted February 11, 2014 70K miles is a long time for brake pads unless they're all highway miles. Quote Link to comment Share on other sites More sharing options...
4x4 Posted February 11, 2014 Report Share Posted February 11, 2014 What is the expected life of brake pads these days? On my GM vehicles I was under the impression I shouldn't have to replace the pads until close to 100K. Brakes on the MKX have always felt good and not made any sounds except here lately when its really cold and wet or one of the two. Quote Link to comment Share on other sites More sharing options...
akirby Posted February 12, 2014 Report Share Posted February 12, 2014 Like I said in the other thread I have never heard of pads lasting 100K unless it's 95% highway miles. Most last 50K-60K and the rears are now wearing out before the fronts. Quote Link to comment Share on other sites More sharing options...
