I am also getting this noise from my 2011 GT with 2200 miles on it when I pull into my driveway which is steep or going over a speed bump.

 

Also my brakes have a major squeal in them when I pull down my driveway slowly. Is this also an issue that anyone else has?

 

this is why i have a loud exhaust.. lol.. and whatever it doesn't cover i just turn up the radio louder.. (when its on) i've heard some suspension bar bushings creak if they aren't lubed up.. i chased one noise and it ended up being a bumper cover clip.. factory operator forgot to "press firmly" during the install.. but i feel your pain.. that sh*t drives me nuts..

 

Yeah it drives me nuts too...Brand new Satng and just worries me a bit. I figure on the brake squeal, the dealer needs to fix and/or replace them under warranty.

 

That squealing you're hearing is no problem of the manufacturing process or the brakes, because the big discs build up either a little or a lot of rust depending on how long they've been sitting around (even inside), the squeal is the sound of the rust being stripped from the discs. Happens to my car without a doubt, then looked online and read about it and felt relieved

 

What pdonket just said. I too get brake squeal, and it is very audible for the first few stops. But after that, the squealing goes away and all stops are normal with no sounds at all.

For the squeals, you will get them the first time you drive your car each day because of the rust pdonket mentioned. The rust is a very thin layer and does not hurt anything.

For me, I get the squeal on my front passenger brake.

 

The creaking could be from a couple of things that pop in my mind right now.

The first is the bushings: The bushings could be defective or made from the wrong materials from the parts supplier Ford buys from (this is common from a Chinese supplier; they tend to cheat and use cheaper materials instead of spec materials and still charge Ford full price per unit or they simply allow defective pieces to pass QC to save themselves money hut still screw Ford).

The underside of a Mustang is prone to rust. Don't worry about the rust; it is supposed to happen over the majority of parts on the under side of your car.
The rust can become a problem if the bearings or solid metal bushings are not fortified against this natural and designed rusting. If so, the metal bushings or bearings could be getting rust into them. This could be a source of creaking. If these are metal bushings, you should not have problems through the creaking. But if they are bearings, I am not sure. The problem I guess could happen is if the rust causes them to seize up an you begin to bend parts instead of them rotating freely as designed.

 

is it just me or do these disc brakes rust quicker than a chevy..

 

They do rust really quickly, I wondered why that was myself. I mean it doesn't much matter, but aesthetically it's annoying to me. Plus I feel like it's a bad rep to have that every time you start driving your car, you have squeaky breaks.

Not a good rep for ford or mustangs to have when in my case the car is almost brand new.

 

and not to mention brake dust galore.. but yeah, doesn't really matter, just irritating.. must be a lower grade of steel/iron.. i guess i need to add brake upgrade to my mod list..
