Bus Stopping Power

[davidbrady]

Hi Guys,

Attached is a good paper on Bus and Truck stopping distances using drum and disc brakes. They look at a fully loaded class 8 truck, loaded to GVWR, and a fully loaded School Bus. Interesting that both are capable of locking their wheels on a high grip surface, and the bus outperforms the truck in stopping distances. Of course, disc brakes outperform drum. Amazing that the school bus is able to achieve over 0.70 g's of stopping deceleration and distances as short as 180' from 60 mph. Turns out that buses can stop pretty well after all, just stand on that pedal and keep your eyes on the road.
