Which description of brake fade is correct?
Correct answer: It can result when the brakes become extremely hot.
Answer options
- AIt can result when the brakes become extremely hot. Correct
- BIt goes away if you release the brakes for a second or two and then reapply them.
- COnly vehicles with drum brakes can experience it.
Why
Brakes that overheat, often from long or heavy braking on a downhill grade, lose much of their ability to stop the vehicle. Letting off the pedal for a moment will not cure the problem, and disc brakes can fade just like drum brakes; relying on a lower gear for engine braking on grades helps prevent it.
