When going down a long, steep slope with a truck, which technique is most advisable for moderating speed?

Question

DentroTest · Accepted Answer

On long downhill slopes, heavy vehicles build up a great deal of kinetic energy because of their mass. If the service brake is used continuously, excessive overheating is generated in the friction elements (discs, pads or drums), triggering the dangerous phenomenon of fading, or brake fatigue, which drastically reduces or eliminates braking capacity. The prescribed and safe technique consists of selecting a suitable gear to take advantage of engine braking and relying on retarder devices (hydraulic or electromagnetic), reserving the foot brake only for brief, occasional corrections. Pressing the clutch removes engine braking and leaves the truck rolling by inertia, dangerously increasing its speed.
