Brakes may be less effective after which condition?

Brakes may be less effective after which condition?

• A. If you have driven through a deep puddle
• B. If you have driven through deep water
• C. If you have driven through floodwater
• D. If you have driven through a flooded street

Answer: (B)

Water on the braking surfaces reduces friction, so brakes may be less effective after you’ve driven through water. When brakes get wet, the pad or shoe can’t grip the disc or drum as well, which can increase stopping distances until they dry out. After passing through water, ease off and test the brakes gently to dry them, then proceed with extra caution until braking feels normal again. Deep water is the most likely to wet the brakes thoroughly, making the effect more noticeable, which is why this condition is the best answer.
