To what temperature do brake components typically heat up during normal stopping?

• A. 100° C
• B. 120° C
• C. 150° C
• D. 180° C

Answer: (B)

Brake components typically heat up to around 120° C (248° F) during normal stopping. This temperature is a critical aspect of brake function because it ensures that the materials used in brake pads and rotors operate effectively. At this temperature, brakes provide optimal performance, allowing for effective stopping power without excessive wear. It's important to note that while braking, the friction generated between the brake pads and the rotors converts kinetic energy into thermal energy. If the temperature were to rise significantly above this level, it could lead to brake fade, reduced performance, and an increased risk of brake failure due to overheating. Therefore, understanding that 120° C is a typical operating temperature helps drivers appreciate the limits of their braking system in normal driving conditions.
