If the rear brakes wear out abnormally fast, this can be caused by defective rear brake pads. The rear wheels may also appear to become excessively dusty. They should be replaced with revised brake pads, and all wheel drive (AWD) vehicles should replace front brake pads as well.Google+

REar Brakes went out at 30,000! Now the AC too!
I'm on my 3rd set of rear brakes, 2nd front brakes and all new rotors. The caliper pins are the problem and Ford won't do anything about it!

replaced rear passenger rotor and pads at 30000 miles still seems like it gives me trouble but great car other then that.

Rear rotors were shot. front rotors were not much better. my mechanic tells me all 500's are like this. Aluminium rotors tend to warp. he suggested I get a set of good After Market Rotors as the OEM uses cheap.

I just had the rear rotors and the right rear caliper replaced along with new brake pads. the rotors were wore down so bad that they could'nt be turned. The caliper was faulty and had to be replaced. A new caliper, brake pads and two new rotors seems excessive every 60000 miles, since most of my miles were highway miles. Also, the front calipers are huge compared to the rear calipers. Maybe ford installed them backwards. Maybe the proportioning valve should proportion more braking on the front and less on the rear.

Before I purchased this car I test drove it 4 times the dealer told me the loud noise from the rear was the bearings. After two day working on the car turns out it needs rear brakes and rotors. That was two months ago, no problem since then but with all the complaints about the brakes I plan to change the pads every 15 thousand miles. Hope this work because it one of the best cars I've ever owned. Mines gets 32~34 mpg on the hwy and 22-25 city.

This is the second set of brake pads for the rear while the front brakes still have 50% life remaining on the original pads.
Rear brake pads worn out, and also problems with the rotors. Was told that they needed to be replaced.
