Brake drum wear typically results from several factors. Primarily, the friction generated between the brake shoes and the drum during the braking process leads to material degradation. This friction produces heat, which can cause the drum to warp or crack if the temperatures exceed certain thresholds. Additionally, heavy braking or aggressive driving habits can accelerate wear, as can poorly maintained braking systems that may cause uneven wear patterns. Contaminants like dirt, moisture, or oil can also contribute to premature brake drum wear, affecting performance and safety.
In contrast, drum brakes utilize a cylindrical drum that rotates with the wheel. When activated, brake shoes inside the drum expand against its inner surface, creating friction to slow the vehicle down. Drum brakes are generally more compact and cost-effective to manufacture, which is why they’re often found in the rear brakes of economy vehicles. However, they tend to perform less effectively in adverse weather conditions and can suffer from brake fade during prolonged use due to overheating.

Uma das grandes vantagens dos tambores de freio é a sua capacidade de lidar com altas temperaturas. Em situações de uso intenso, como em descidas acentuadas ou em terrenos difíceis, os tambores conseguem dissipar o calor de maneira eficiente, reduzindo o risco de perda de eficiência de frenagem, um fenômeno conhecido como fading. Para os proprietários de Land Rover Series, esta característica é um grande benefício, pois permite que o veículo enfrente desafios em trilhas e estradas difíceis sem comprometer a segurança.
