Re: EXHAUST BRAKE
I drive for a school district where we're in the high mountains. All out buses have Telma retarders. They are electromagnetic and work great. Most of them are 4 stages with a lever to activate it near the steering wheel. In the snow it's like having a hand brake on the bus, good for freestyle bus driving. No one tell my boss! Oh yeah and the kids aren't on the bus when I'm screwin around either. Have to be careful with them though when it's icy out cause that rear will slide.
