School Bus Air Brake Test Procedure

Stopping a school bus requires controlling a massive amount of energy. Most buses use air breaks because the human leg can only take so much pressure. If you are buying a bus, you need to have a school bus air brake test procedure in place to keep an eye on the performance of the braking system.


Physics and buses are two words rarely associated with each other. They should be. A school bus is an exercise in the movement of energy and mass. Being so large, a lot of energy is needed to get a bus moving. When it is time to stop, the braking system must have the ability to bleed off all that energy. This process is "turbo charged" when passengers are added to the bus since they increase the mass involved significantly.

I cannot emphasize enough how important it is to test and maintain the brakes on your bus. If the brake system fails, there is a good chance people are going to be hurt and even killed. You can do a search on Google for "school bus accidents" to see just how often this happens. Here is one approach to testing your brakes.
