Here is a good site if anyone wishes to learn a bit more about friction materials
for vehicles.
It is geared for the mud hen (OEM or stock) level. Higher end stuff will have
better performance to out right scary for street. Found some really, really cool
stuff when designing windgenerator disc brakes...they were so good, it would
stop the hub so fast the blades would break off...so my aerodynamists calculated
Properties of Friction Lining and Pad Materials (Automobile)autobrake autobrakefriction frictionmaterial
At/above that temp, the friction material will outgas much, much more
and 'float' the friction material off the cast iron surface (fad). The
stuff I use is off this chart to give perspective on what 'performance'
level vs OEM is. The 'good material' is what I consider HD stuff you
can buy at local auto supply stores
Notice that their performance drops off at around 300C...about 572F
for the 'good material' and about 200C..about 392F for their OEM stuff
