Control & OperationPregunta 78 de 120
What is the correct way to make a normal stop in a vehicle with air brakes?
a.Stab the pedal down and release repeatedly
b.Push the brake pedal down steadily and control the pressure so the vehicle comes to a smooth stop
c.Pull the trailer hand valve first and then use the pedal
d.Shift to neutral and let the vehicle coast to a stop
Explicación
Steady, controlled pedal pressure produces a smooth stop and keeps the vehicle in line. Stab braking is an emergency technique, the trailer hand valve alone can cause a trailer skid, and coasting in neutral removes engine braking and control.
