What is the Brake drum:
The brake drum is a type of cast iron shaped like a tambourine, which is fixed with the tire and rotates at the same speed. When braking, apply oil pressure to push the brake shoes to contact the brake drum inner rim, we can control the rotation of the wheel to achieve the purpose of braking by the friction force comes from contact.

Structure of drum brakes
Drum brakes are a brake system with brake drums (rotor) which rotate with the wheels. Inside each drum are
brake shoes fitted with brake linings (friction material). Pistons (pressure mechanism) press against the drums
from the inside to generate braking force, thus making is possible to decelerate and stop the vehicle.

How drum brakes work
When the driver steps on the brake pedal, the power is amplified by the brake booster (servo system) and
changed into hydraulic pressure (oil-pressure) by the master cylinder. The pressure reaches the brakes on
the wheels via tubing filled with brake oil (brake fluid). The delivered pressure pushes the pistons on the
brakes of the four wheels. The pistons press the brake linings, which are friction materials, against the inside surfaces of the brake drums which rotate with the wheels. The linings are pressed on the rotating drums,
which in turn decelerate the wheels, thereby slowing down and stopping the vehicle.
