Hello,
If you are unable to fix yourself, than yes you can drive it to local shop. You still have front brakes working.
If you can repair yourself start by removing rear tire than brake drum and look for broken parts. Most likely they will fall out when you remove drum.
Replace worn or broken parts which are inexpensive for your car.
Check for leaking fluid from broken break lines and check fluid level under hood. Keep me informed N I'll help. Paul

Yes, I have a 2011 Milan as well and both sides of mine went out. One last year (2013) and the other side recently. My car is no longer under warranty and the dealer said they it would be $417 to repair. Ford needs to fix this issue because from what I have been reading it is a common problem and it is a safety issue!

What size are the bolts? Did you break them? Your local part store will have have caliper mounting bolts that can be purchased.

There are 2 filiments in the light bulb. One is for running lights and the other is for brake and turn signal lights. Simply replace the bulb and you should be ok.

there is a light out sensor on each side of the rear light. they are going bad all the time, you can order it at your local dealer for around 40 bucks. it comes with the light socket assembly

check wiring harness behind light assembly for a loose or broken ground wire. this would not affect the third or "cargo" brake light

If you have an aftermarket trailer towing plug on it, that's where i would look first. Something is shorting out in there, or you have a broken wire or ground somewhere. Proabably near the back where gravel stones can hit.

same bulb but 2 seperate elements. wiring diagram u should be able to obtain from your local auto parts store like autozone(preferred)

Well, have you checked the fuse? Maybe stick another one (of the same size) in there anyway. If that's ok, then check the stop light switch. It'll be somewhere along the brake pedal linkage/ arm under the dash or under the hood around the linkage or master cylinder. Look around. You can short across the wires temporarily to see if they light up and then you'll know if that's it.
