[Biturbos4] Brake upgrade / EBC Greenstuff

[John Koenig]

I replaced my OE pads with EBC Greenstuff, probably for the same reasons
you're considering them.  I am in the process of trying to troubleshoot a
problem I have with vibration, which I first thought was warped rotors.  The
car is street/highway driven, and I'm getting to be an old man, so that
usually means anticipating traffic, emphasizing smoothness and not using the
brakes too hard, as a general rule.  What I notice though, which tends to
refute the warped rotor theory, is that the vibration seems based on
conditions.  It is usually most noticeable after the car has been sitting a
day or two, which to me suggests some kind of pad/rotor interaction or
corrosion issues.  A few blasts of hard braking tend to diminish the problem
a lot, and I've never heard of that with warped rotors.  I guess maybe my
street driving isn't using them hard enough.

Please note:  This is by no means definitive; I may have other issues, and
I'm very reluctant to dismiss the product as inferior when I have too many
variables.  Just responding like you asked ...

John
