They employ friction to slow or stop the vehicle.
THOSE ARE DISC BRAKES
On a Ford Explorer : There are disc brakes on the front and ( starting with the 1995 model year ) there are disc brakes on the rear also ( instead of drum brakes on the rear )
No. Drum brakes expand inside a rotating drum to stop the vehicle, disc brakes squeeze in against a rotating disc.
Disc brakes are not subject to "fade" which occurs when drum brakes overheat and lose the ability to stop, another advantage of disc brakes is that they tend to stop in a straight line unlike drum brakes which often "pull" to one side. Yet another advantage of disc brakes is that they self adjust by drawing brake fluid in behind the piston while it is common for the self adjusters in drum brakes to seize due to corrosion then the drum brakes quit adjusting then the brake pedal goes lower and lower.
No, they are inferior to disc brakes. Drum brakes were used from the beginning of the auto up until the late 60s. Drum brakes are more prone to overheating than disc brakes. Disc brakes also shed water much better than drum brakes which improves stopping distance in wet conditions. Disc brakes apply pressure more evenly than drum brakes thus improving stopping distance. Disc brakes are superior in every way.
This will greatly depend on what kind of brakes you have and which parts you are trying to replace. Do you have disc or drum brakes? If you have disc brakes, do you want to replace the calipers, pads, or rotors? If you have drum brakes, do you want to replace the drum, or the shoes?

There's no guarantee that they will. Disc brakes have a higher initial cost and are prone to heating more quickly than foundation drum brakes.
