You’ve just gone through flood water. What should you do to make sure your brakes are working properly?
- A Accelerate and keep to a high speed for a short time
- B Go slowly while gently applying the brakes
- C Avoid using the brakes at all for a few miles
- D Stop for at least an hour to allow them time to dry
Why this is the answer
Water on the brakes will act as a lubricant, causing them to work less efficiently. Using the brakes lightly as you go along will quickly dry them out.
Why the other answers don't fit
- A
- Accelerate and keep to a high speed for a short time — Speed does not dry brakes, and you would be doing it on brakes you have not yet tested.
- C
- Avoid using the brakes at all for a few miles — Leaving them wet is exactly the problem you are trying to fix.
- D
- Stop for at least an hour to allow them time to dry — Light use dries them within seconds. There is nothing to wait for.

Where this question comes from
