What is brake fade?
a.The brakes slowly releasing while parked
b.A reduction in braking power from overheated, overused brakes
c.The lag before air reaches the brakes
d.The loss of air pressure overnight
Explanation
Brake fade happens when brakes are used so much that they overheat and lose stopping power. Excessive heat causes the drums to expand and the linings to become less effective, so the brakes do not grip as well. Fade is a major risk on long or steep downgrades.
