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

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.
