In golf cart drum brake system, the brake drum is mounted to and rotates with the wheel hub. Inside, the stationary brake shoes, lined with friction material, are actuated by a wheel cylinder. When you press the brake pedal, the shoes expand and press against the drum's inner surface, converting kinetic energy into heat to slow the cart. Key issues arise from:
Worn Shoes: Thinning friction material reduces stopping power and can expose metal, scoring the drum.
Glazed or Scored Drums: A damaged drum surface prevents proper shoe contact, leading to grabbing, vibration, or noise.
Worn Hardware: Weak or corroded springs and pins prevent shoes from retracting properly, causing drag and overheating.
