Why should you test your brakes after driving through a ford?

Explanation: At a ford, the road passes through a stream at a place where the water is normally shallow. When you've gone through the water, you should test your brakes and if necessary dry them out. To do this, first check that you won't cause danger to traffic behind. Then apply a light brake pressure while moving slowly. Make sure your brakes are working properly before resuming normal driving.
