If braking action has been reduced due to water or rain, what should you do to restore proper braking action?

When braking action has been compromised due to water or rain, lightly pumping the brakes several times can help restore proper braking function. This technique works by allowing the brake pads to clear any moisture that may have accumulated on them, as well as by generating friction that can help dry out the brake system.

Applying the brakes firmly may cause them to lock up, particularly on wet surfaces, which could lead to skidding or loss of control. Increasing speed is inherently dangerous in slippery conditions, as it reduces the effectiveness of braking and increases the stopping distance required. While turning on hazard lights can be helpful in certain conditions for visibility, it does not directly contribute to improving braking performance.

Thus, lightly pumping the brakes is the safest and most effective method to regain adequate braking action in wet conditions.
