There are advantages to air brakes - it also depends where you live and how large the bus is. Living in the mountains, air brakes are preferable. They have a good feel to them when using them. Here's one consideration; if a hydraulic line fails, you lose braking power. If an air line goes, the wheel will brake. Air pressure is used to disengage the brake, so when there is no air the brakes engage.
You may want to read up on air brakes through the DOT - Good luck with it. |
