Are wet brakes more or less efficient at stopping your vehicle than dry brakes?

1. More efficient

2. Less efficient

3. Equally efficient

4. Not applicable

The correct answer is: Less efficient

Wet brakes are less efficient at stopping your vehicle than dry brakes. This is because when brakes are wet, water can create a barrier between the brake pads and the rotor, reducing friction and making it harder for the brakes to stop the vehicle. In contrast, dry brakes have more direct contact with the rotor, allowing for better friction and thus more efficient stopping. Option A is incorrect because wet brakes are in fact less efficient. Option C is incorrect because as explained, wet brakes are not equally efficient as dry brakes. Option D is not applicable because it does not provide an answer to the question.
