Brake rotor resurfacing...

[Grant Lenahan]

My pulsing pedal problems have never turned out to be warpage. Always  
pad deposits.
I realize this violates long held "wisdom", but its becoming more and  
more accepted. You can also go to stoptech's web page and see what  
they have to say about it.
Mis-diagnosed by audi many times, and under warranty, i was fine with  
rotor replacement. Now, less so.
