Question 1646 in the bank

Continuous braking on a winding descent can cause:

  1. Correct answer: Over heating and weaker braking than normal.
  2. Over heating and stronger braking than normal.
  3. Cooling of the breaks and weak braking.
  4. Continuous braking has no negative affect.

Why this is the answer

The correct answer in the official bank: Over heating and weaker braking than normal.

Long, continuous braking on a descent makes the brakes very hot from friction, and overheated brakes lose their grip, so braking becomes weaker than normal and stopping distances grow. On long downhill stretches, shift to a lower gear and let engine braking hold the speed, using the brakes only from time to time. Heat never makes braking stronger.
