The lining material on the brake shoe is typically made of a heat-resistant compound, such as semi-metallic or organic material. This lining is responsible for generating the friction necessary to slow down or stop the vehicle. When the lining material comes into contact with the drum, it creates a high amount of friction, which converts the kinetic energy of the rotating drum into thermal energy. This process causes the drum to slow down and ultimately stop the vehicle.
The brake shoe also plays a crucial role in maintaining proper brake balance and preventing uneven wear. It is designed to distribute the braking force evenly across the drum surface, which helps to prevent the formation of hot spots or glazing. Additionally, the brake shoe can be adjusted to compensate for wear, ensuring consistent and reliable braking performance. Regular inspection and maintenance of the brake shoes are essential to ensure their proper function and maximize their lifespan.
In conclusion, the brake shoe is a vital component of a drum brake system. Its primary function is to generate friction against the rotating drum, allowing the vehicle to slow down or come to a stop.
