Question: 1 / 400

If a vehicle swerves to the right when brakes are applied, what could be the fault?

Right brake lining is worn

The left brake lining is wet

When a vehicle swerves to the right when brakes are applied, it often indicates that there is uneven braking occurring between the left and right sides of the vehicle. In the context of the fault being the left brake lining being wet, this suggests that the left brake is not gripping as effectively as the right brake. When the right brake is applied normally but the left brake does not provide the same level of resistance because it is compromised (in this case, wet), the vehicle will tend to pivot towards the side with stronger braking force—in this instance, to the right.

This uneven braking is important because it highlights how brake performance can be affected by environmental conditions or mechanical failures. A wet brake lining will not generate the same friction as a dry one, resulting in less deceleration on the left side and causing the vehicle to swerve towards the right where the braking force is greater.

Therefore, the reasoning for this answer focuses on the relationship between braking forces on either side of the vehicle and how they influence vehicle dynamics during a braking maneuver.
