Reverse brake squeal

[sabanist]

Hi, I own a 2007 Ford Edge SE.  It has been a while since we changed the brake pads.  I plan on doing this project but I want to make sure I replace the right parts for the problem.  The vehicle squeals while reversing, especially in the morning.  It sits in a carport but not a garage.  I've read where moisture can cause it.  However, even when warm it squeals some

 

There are no performance issues noticeable with the brakes other than that.  I figured I would replace them because it has been maybe 4 years now.  

 

When we had the breaks done last, the rotors were not replaced. Im assuming they are the OEM rotors.  

 

Is it recommended I do the front and rear brakes and rotors,  or front OR rear?  

 

I know when we had the last brake job done, it was because of the reverse squealing and it did not fix the noise.  We were about to move so i didn't have time to deal with the shop that did it.  now I plan on doing them again myself.  so if there is anything I should look for or replace to fix the issue, I'd appreciate it.  Thanks

That squeal is a common problem, especially with Ford pads.  Very common first thing in the morning too, after the rotors have "cooked" in the humidity and have built up surface rust.

 

When I switched to Power Stop brakes, the problem went away completely.  Still get light rust buildup, but it grinds away within a few seconds of first brake application.

My 2009 Edge Limited has the same problem. Also, it's always recommended to change both front and rear brakes. Same for the rotors. As for the rotors it depends how worn the are.
