Drums are made from cast iron and are named for their “drum-like” shape. Drum brakes work by forcing 2 arched “shoes” housed within the drum, to expand outward into the inner wall of the spinning drum, using hydraulic and centrifugal force. This generates friction, slowing the drum and your bike.A disc brake system is comprised of a large metal rotor, 2 flat brake pads and a hydraulic clamp called a “caliper”. Pressing the brake with disc brakes, forces brake fluid to fill the caliper. A metal piston inside the caliper is then forced against the back of each brake pad. This presses the pad’s friction material against the spinning rotor, quickly slowing the brake rotor.My suggestion is if you had a bike with drum break previously then you should go with drum break only, do not try the disc break as it stops the bike at sudden. and if you could not control the bike you and bike may fall and you could get injured.
