* Check your owner's manual: This is the most reliable source of information.
* Look at the brakes themselves: If you can safely access the rear wheels, you'll be able to see if they are disc (a round rotor visible behind the wheel) or drum (a cylindrical drum).
* Check your Vehicle Identification Number (VIN): You can use the VIN to look up the specifications online through various parts websites or your Ford dealership.
While most were disc, always confirm by checking one of the above methods.
