Hi All;
Seeing the posts on the Carbotech brake pads triggered a comment I thought
I'd throw out for any of you using the Porterfield Carbon Kevlar (R4) pads.
From my experience, I strongly recommend replacing these pads when they
reach approximately 1/2 thickness. I say this as I've had 2 instances now of
the pad material completely separating from the backing plate from extreme
heat build-up on well worn pads. The pads become discolored, with a pinkish
hue. I've talked to Porterfield and they confirmed that they've seen this
before. My theory is there's a lot more heat dissipation capability in a
thicker pad, and on my car the fronts get quite a workout. Other than this,
I'm very happy and pleased with their overall performance. I get
considerably longer life, less brake fade, and less overheating to the point
of boiling the fluid with the carbon kevlar pads, than with the DS-11's I
used to use. FYI....
