[s-cars] brake shudder (Joe Pizzimenti)

[Eric Phillips]

Mike,

I have Hawk HPS pads in 993TT calipers on RS2 brackets over D2 A8L
rotors.  I do not have deposits, nor have I ever had deposits.  I
bedded them in via the 90 -> 5 -> 90 (x10) and have run them since
with no hassles.  I think the garnet paper and a re-bedding like I did
should help you out.  Stock pads for the Porsche application, IIRC,
are Textar.

I've liked my HPS pads so far.  They howled a bit to start, but I
rebedded them, and they shut up.  :)
