Disc brakes and drum brakes are two different types of braking systems used in vehicles. Here are some key differences between the two:
1. Design: Disc brakes consist of a rotor (disc) that is attached to the wheel hub and calipers that contain brake pads. When the brake pedal is pressed, the calipers squeeze the brake pads against the rotor to create friction and slow down the vehicle. Drum brakes, on the other hand, consist of a drum that is attached to the wheel and brake shoes that press against the inside of the drum to create friction.
2. Heat dissipation: Disc brakes are better at dissipating heat compared to drum brakes. This is because the rotor is exposed to the air, allowing heat to dissipate more quickly. Drum brakes, on the other hand, are enclosed within the drum, which can cause heat to build up more easily.
3. Performance: Disc brakes generally provide better stopping power and are more responsive compared to drum brakes. This is because disc brakes have a larger surface area for the brake pads to make contact with the rotor, resulting in more efficient braking.
4. Maintenance: Disc brakes are easier to maintain and replace compared to drum brakes. The brake pads on disc brakes can be easily accessed and replaced without having to remove the entire braking system. Drum brakes, on the other hand, require more labor-intensive maintenance and replacement procedures.
5. Cost: Disc brakes are typically more expensive to install and maintain compared to drum brakes. However, the improved performance and durability of disc brakes may justify the higher cost for some vehicle owners.

Disc Brakes
Advantages:
- More stopping power
- Less fade
- Longer life
- Less noise
- Cleaner (less dust)
Disadvantages:
- More expensive to purchase and replace
- More complex to service
Construction:
- Consists of a rotating disc mounted on the wheel hub and a caliper that clamps the disc with brake pads.
- When the brake pedal is pressed, hydraulic or mechanical force applies pressure to the caliper, forcing the pads against the disc.
Working Principle:
- Friction between the brake pads and the disc slows down the rotation of the wheel.
- This rotational resistance creates a braking force that opposes the vehicle's momentum.
Drum Brakes
Advantages:
- Less expensive to purchase and replace
- Simpler to service
- More resistant to corrosion
Disadvantages:
- Less stopping power
- More fade
- Shorter life
- More noise
- More dust
Construction:
- Consists of a cylindrical drum mounted on the wheel hub and brake shoes that expand inward to contact the inner surface of the drum.
- When the brake pedal is pressed, hydraulic or mechanical force expands the brake shoes, pressing them against the drum.
Working Principle:
- Friction between the brake shoes and the drum causes the drum to slow down, and with it, the wheel.
- This rotational resistance creates a braking force that opposes the vehicle's momentum.
