Why do disc brakes heat up less than drum brakes?
Mechanics (different vehicle systems)
Explanation
**Disc brakes** heat up less than drum brakes mainly because they are **well ventilated**. This ventilation allows air to circulate around the discs, helping to dissipate the heat generated during braking.
- When brakes are used, heat is generated due to the friction between the pads and the discs or drums. If the brakes become too hot, their effectiveness decreases.
- Disc brakes, being exposed to the air, have a better capacity to cool down quickly compared to drum brakes, which are more enclosed and have less ventilation.
Therefore, **ventilation** is key to keeping disc brakes at an appropriate temperature, ensuring optimal performance and preventing overheating.
