The door latch
In an air brake system, the air compressor is connected to the engine through gears or a v-belt.

Forcing an automatic transmission into a lower gear at a high speed could damage the transmission and also lead to a loss of ability to engine brake. Drive at a speed that will allow you to control your vehicle without overusing your brakes. When determining a safe speed to drive, you should take into account the steepness of the grade, the length of the grade, the weight of your vehicle, road conditions, and weather conditions.

Drive on the shoulder.
If you see, hear, smell, or feel anything that could indicate trouble while you are driving, you should stop and inspect the source of the unusual occurrence.
