Question

Difficulty: EasyBrake Failure

During a total service brake failure, shifting the transmission into neutral is recommended because it prevents engine power from propelling the vehicle.

Answer: Answer

Answer

False
Shifting the transmission into neutral disconnects the engine from the wheels, which removes all engine braking capability. When service brakes fail, drivers must downshift into lower gears so that engine compression helps slow the vehicle down.

Step-by-Step Solution

1
Identify the primary mechanism available to slow a vehicle when service brakes fail
Engine compression braking generated by downshifting through gears
Engine braking provides essential retarding force to control vehicle speed when mechanical service brakes are inoperable
2
Determine the physical effect of shifting into neutral during a brake emergency
The engine is disconnected from the driveline, entirely eliminating engine braking
Coasting in neutral removes all drivetrain resistance and increases stopping distance
