I've got a set sitting in the truck, waiting for the install. I got them from AutoZone and they come with a lifetime warranty (no questions asked, dodn't even need my receipt since they have the purchase information on computer).
I used a set on my 98 gasser and they lasted twice as long as the factory pads. Then I got a free replacement set which stayed on the truck when I sold it.
On the school buses, that I can no longer work on, we use Performance Friction pads on the buses with hydraulic brakes. They're the same brakes that Bad340fish has on his battery truck.
