Hey, thanks Ranger. That was interesting. As I read that, I understood that one possible reason I have had little trouble with warping or with pad deposition, is that I ALWAYS buy the cheapest (abrasive) pads. Not so much because they are cheap, (reason enough) but because they are quiet. I also usually drive very gently, and generally avoid hard braking.

Yes, very good reading. The only thing I wish he'd expanded on is a paragraph near the top that he blew right through without stopping:

With one qualifier, presuming that the hub and wheel flange are flat and in good condition and that the wheel bolts or hat mounting hardware is in good condition, installed correctly and tightened uniformly and in the correct order to the recommended torque specification, [...]
I think sloppy installation is a lot more prevalent than poor matching of brake pads to driving conditions, and I know from my own experience that I can get improvement (though maybe not a complete cure) in a car with pulsating brakes by just retorquing the lug nuts with a torque wrench in the correct manner to the correct torque. I don't disagree with anything he said and he'* certainly very knowledgeable, but I think a large percentage of brake complaints in Joe Public average everyday cars is due to some idiot slamming the front wheels on with an impact wrench.

The service manual does say you can use a torque stick with an impact wrench, but hand tightening as a final step is best, IMHO. Whenever one of our cars goes in for service that involves taking wheels off, I redo the lugnuts when I get it back home, just to be sure.
