2. Packaging constraints: In some vehicles, there may be limited space available for the braking system, particularly in the rear axle area. Drum brakes have a more compact design compared to disc brakes, making them a better fit for vehicles with tight packaging constraints.
3. Ease of maintenance: Drum brakes typically require less maintenance compared to disc brakes. For example, drum brake pads generally last longer and are easier to replace compared to disc brake pads. This can be advantageous for fleet vehicles or budget-conscious consumers.
4. Heat dissipation: In heavy-duty vehicles or vehicles that frequently carry heavy loads, drum brakes offer better heat dissipation compared to disc brakes. This is because the enclosed design of drum brakes allows for more effective heat transfer from the brake shoes to the surrounding environment.
5. Noise and vibration: Drum brakes tend to produce less noise and vibration compared to disc brakes. This can be advantageous for luxury vehicles or vehicles that prioritize comfort and refinement.
However, it's important to note that while drum brakes have certain advantages in terms of cost, packaging, and maintenance, they generally provide inferior braking performance compared to disc brakes. Disc brakes offer better stopping power, fade resistance, and responsiveness, which is why they are increasingly being used on all wheels of modern vehicles.
