What are the advantages and disadvantages of drum brakes and disc brakes for motorcycles?

[MollyLee]

Motorcycle drum brakes and disc brakes have the following advantages and disadvantages: I. Disc Brakes: 1. Advantages: More stable, shorter braking distance, hence safer, high braking sensitivity, automatic gap adjustment, longer lifespan of brake pads, less effort required for braking, easier maintenance, and faster heat dissipation. 2. Disadvantages: Improper use can easily lead to lock-up, causing the bike to fall, though most now come with ABS anti-lock systems. They are more susceptible to external factors; for example, in snowy conditions, ice formation on the disc can cause temporary brake failure. Due to their tight contact, they may produce some noise and are prone to oil leaks. They also have higher costs and require more from the hydraulic system. II. Drum Brakes: 1. Advantages: Less affected by external factors, less prone to lock-up, silent operation, and lower cost. 2. Disadvantages: Braking sensitivity is not as good as disc brakes, manual gap adjustment is required, shorter lifespan of brake pads, more effort required for braking, harder to maintain, slower heat dissipation, and brake dust tends to accumulate inside the drum.
