Air Brake Practice Test

Are front-wheel brakes effective under all conditions?

1. True

2. False

The correct answer is: True

Front-wheel brakes are not generally effective under all conditions, so the correct choice is actually 'False.' In specific situations, front-wheel brakes can be less effective, particularly when dealing with slippery surfaces such as ice or snow. Under these conditions, the rear wheels may lose traction first, leading to a potential loss of control. Additionally, because the weight shifts to the rear during braking, the front brakes might not provide the necessary stopping power required under certain conditions, particularly in emergency situations where sudden stops might be needed. Therefore, while front-wheel brakes are crucial and typically offer substantial braking force in many driving scenarios, their effectiveness can vary depending on external conditions, making the statement that they are effective under all conditions inaccurate.
