What to Do When the Brake Drum Overheats?

[McRemington]

If the vehicle is equipped with a water sprayer, open it to cool the wheel hubs with water. If not, park the vehicle and let it cool down naturally before continuing to drive. Below are specific details about brake drums: 1. Introduction: The brake drum is the friction mating part of a drum brake system. Besides requiring the necessary strength and rigidity as a component, it should also have as high and stable a friction coefficient as possible, along with appropriate wear resistance, heat resistance, heat dissipation, and thermal capacity. 2. Design Requirements: Poorly designed brake drums are prone to deformation when heated; mechanical deformation can also occur due to unbalanced forces, leading to poor contact between the shoe and drum, which increases pedal force and travel. Excessive out-of-roundness on the working surface of the brake drum can cause self-locking, vibration, and noise. Therefore, the brake drum should have sufficient wall thickness, and axial or radial reinforcing ribs should be cast near the opening on the outer surface to enhance strength.
