    Use a jack to lift the vehicle off the ground, and then secure it with jack stands. Ensure the vehicle is stable before proceeding. Once secure, remove the lug nuts entirely and take off the wheel to access the drum brake.


    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.
