Question

Difficulty: MediumCoasting and Vehicle Control

Coasting with the clutch pedal fully depressed while slowing down reduces mechanical wear on the footbrake because the transmission is disengaged from the engine.

Answer: Answer

Answer

False
The statement is false because pressing the clutch down eliminates engine braking assistance, forcing the footbrake to absorb all the vehicle's kinetic energy and thereby increasing mechanical wear.

Step-by-Step Solution

1
Analyze the mechanical consequence of keeping the clutch pedal depressed while decelerating.
Disengaging the clutch separates the engine from the drive wheels, removing natural engine braking.
Engine braking provides significant retarding force that aids standard deceleration.
2
Determine the impact of losing engine braking on the vehicle's friction braking components.
The footbrake must perform 100% of the retarding effort, accelerating brake pad and disc wear.
According to Highway Code Rule 122, coasting eliminates engine braking and places heavier demands on the footbrake.
