Correct answer

  • CEl roce prolongado de las pastillas o zapatas contra los discos o tambores.Prolonged rubbing of the pads or shoes against the discs or drums.
Explanation

Brakes overheat mainly because of prolonged rubbing of the pads against the discs or of the shoes against the drums, for example when braking continuously on a long downhill stretch. Air or a lack of fluid reduces braking efficiency, but does not heat the brakes.
