Question: 1 / 400

What is one effect of using a truck's service brakes too frequently?

Improved braking effectiveness

Increased wear and potential overheating

Using a truck's service brakes too frequently can lead to increased wear and potential overheating. This is primarily because the service brakes are designed for regular use to slow down or stop the vehicle. However, excessive application generates significant friction, which not only wears down the brake components like pads and drums but also creates heat. When the brakes overheat, their effectiveness can diminish, leading to brakefade, where the braking power is significantly reduced until the brakes cool down. This can be particularly dangerous in situations requiring sudden stops or when descending hills. Proper brake usage includes recognizing when to use engine braking or other methods to avoid over-reliance on service brakes, ensuring they remain effective and have a longer operational lifespan.
