What are the requirements for cdl air brake test
The air brake system needs compressed air to work. Compressed air will be used as energy that the vehicle will use to apply pressure to the brake shoe. Air brake system is used in heavy vehicles like trucks, trailers, buses. Does not require hydraulic fluid and because of that, the air brake circuits can be removed or attached very easy by the truck drivers. It is easy, but only if the drivers were properly trained for that.
