Road Signs

You are driving down a long, steep hill. Your brakes begin to feel weaker each time you press the pedal. What is the safest action?

Ontario road sign — Shift to a lower gear to use engine braking and reduce brake use
Show Answer & Explanation
Correct Answer: B. Shift to a lower gear to use engine braking and reduce brake use

Brake fade is caused by overheated brakes losing friction. A lower gear uses engine resistance to slow the vehicle, giving the brakes time to cool. Once at the bottom, have the brakes inspected before continuing on another descent.

Why the other answers are wrong

  • A.Keep applying the brakes harder to compensatePressing harder overheats the brakes further and accelerates brake fade to complete failure.
  • C.Accelerate to get past the hill fasterIncreasing speed makes control harder and extends the danger zone; the fix is reduced demand on the brakes.
  • D.Turn the steering wheel side to side to slow downSteering side to side reduces only a little speed and destabilizes the vehicle; engine braking is the correct technique.
