To cover the brakes, the driver first applies the brakes lightly for a few seconds, then releases them for a few seconds. This process is repeated as often as necessary to keep the vehicle at a safe speed. The key is to apply the brakes just enough to slow the vehicle down, but not so much that the brakes overheat or the wheels lock up.
Covering the brakes can be an effective way to slow down a heavy vehicle, but it is important to use the technique correctly. Using too much brake pressure can cause the brakes to overheat and fail, which could lead to an accident. It is also important to release the brakes occasionally to allow them to cool down.
