A brake shoe is a curved friction component used in drum brake systems. It is mounted inside the brake drum on the wheel. When the brake lever is applied, the brake shoes are pushed outward by hydraulic or mechanical force, pressing their friction lining against the inner surface of the drum, which generates friction to slow or stop the wheel. Brake shoes are essential in rear-wheel braking systems of motorcycles, scooters, and some e‑bikes, offering reliable braking, low maintenance, and durability. The friction material is designed to resist heat and wear over repeated braking cycles.
