b.Select a low gear before the descent and use engine braking with the brakes
c.Coast in neutral to save fuel
d.Ride the brakes continuously
Explicación
Before a long downgrade, shift into a low gear so engine braking helps control speed, and use the service brakes intermittently to avoid overheating them. Riding the brakes all the way down can cause brake fade, a loss of braking power. Choosing the right gear early is key to a safe descent.
