Question

Difficulty: MediumBrake Failure Management

If a vehicle experiences complete service brake failure while traveling on a level roadway, shifting the transmission into Neutral immediately is the correct first action to slow down the vehicle.

Answer: Answer

Answer

False. Shifting into Neutral removes engine braking, which is critical for reducing vehicle speed during a total brake failure.
The statement is false because placing the vehicle in Neutral eliminates engine braking—one of the key methods to reduce speed during a brake failure emergency. Correct procedure requires keeping the transmission engaged and downshifting to lower gears while attempting to pump the brake pedal or applying the parking brake progressively.

Step-by-Step Solution

1
Analyze the effect of shifting to Neutral during brake failure.
Disengaging the transmission prevents engine compression from slowing the drive wheels.
Engine braking (achieved by downshifting through lower gears) is a vital tool to reduce speed safely when foot brakes fail.
2
Identify the proper initial actions during brake failure.
The correct response is to pump the brake pedal rapidly to rebuild hydraulic pressure (if non-ABS) and downshift to lower gears to slow the vehicle, followed by controlled use of the parking brake.
Maintaining drivetrain engagement in lower gears helps control vehicle speed before coming to a safe stop off the roadway.

Key Concept

Proper emergency procedures for brake failure management, specifically the role of engine braking versus neutral coasting.
