Red Seal Motorcycle Technician Practice Exam

Which material is frequently used for motorcycle brake pads?

1. Aluminum

2. Organic compounds

3. Wood

4. Plastic

The correct answer is: Organic compounds

The correct choice is organic compounds, as they are one of the most commonly used materials for motorcycle brake pads. Organic brake pads, also known as polymer brake pads, are primarily made from a mixture of various materials including rubber, resins, and various fillers. These compounds are favored for their excellent performance in terms of friction, low noise, and reduced wear on both the brake pads and the rotor. They provide smooth braking performance at a lower operating temperature compared to some other pad materials, making them suitable for various riding conditions. In the context of braking systems, the use of organic compounds ensures effective stopping power while minimizing the impact on other components of the braking system. Therefore, they are widely used in both street and sport motorcycles, where balanced performance and rider comfort are important considerations. The other materials mentioned do not commonly meet the specific requirements for motorcycle brake pads. Aluminum may be used in other components like calipers but is not suitable for compression and wear in pad form. Wood is not practical due to its inability to withstand the high heat and pressure generated during braking. Plastic lacks the necessary durability and friction characteristics required for effective braking performance.
