DISC BRAKES
Disc brakes are the most common and also most effective means of stopping a vehicle. This type of braking system usually consists of a disc that rotates at the same speed as the wheel to which it is attached, straddled by a brake caliper. The caliper contains brake pads which are operated by one or more small pistons that squeeze against the surface of the disc to slow it down or even stop it. Compared to the drum version, disc brakes operate much more efficiently at high temperatures and wet conditions, basically by having a more complete design.
DRUM BRAKES
A drum brake is made of a drum-shaped housing (which is usually out of cast iron) that is attached to the wheel. Inside the drum there are usually two brake shoes curved around the interior that are forced into contact with the inner drum. The contact of the pads with the inner section of the drum housing provides braking. Drum brakes are very simple and generally very effective, except under heavy or hard use and under wet conditions, which is why they are less and less common on modern cars.
