What might happen if using the brakes continuously causes them to overheat?

Explanation: Whenever you brake, the brakes convert the moving energy of your vehicle into heat. Continuous use of the brakes, particularly from high speed or on long steep descents, can cause the shoes and drums to overheat. This will make them less effective and, in some cases, they may not work at all.
