brake pad physics

I'm a physics TA at the University of Minnesota and now that I've assigned a tough problem to my students I'm having trouble finding the correct answer.
The question dealt with the difference in power dissipation between locking your brakes and skidding to a stop and applying pressure to the pads that stops just short of locking the wheels. I remember hearing in driver's ED that in an emergency it was more efficient (meaning you'd stop faster) to apply pressure just short of skidding.
I have most of the problem worked out, but I'm having trouble finding a couple of values:
What's the maximum pressure you can apply by pushing down on the brake pedal. I'm guessing this of the order of the maximum pressure a brake hose can endure but I havn't found this listed anywhere.
Secondly, what is the coefficient of kinetic friction between a brake pad (asbestos or ceramic?) and a brake disc (cast Iron)?
Any good leads would help
