Apparently when me and Reid bed in my GT-R.spec (Vr) pads on friday (day before the expo), we didn't do them 'hard enough'. That's what Andie said.

During my first session at BeaveRun, everything was fine till the end of the back straight on the 5th lap. I developed a HUGE shudder, and the car was almost impossible to control, let alone slow down. The next few laps were fun, and I went slower to get more time learning the line instead of going in to examine my brakes.

When I got in, the first words out of my instructor were "warped rotors". I had an extra set, but wanted to see if I could find Andie first.

Me and YOU (trey) went for a walk, "looking for a piece of Andie...". :lol:

When we found him and I introduced myself, I pointed to my car. From about 75 feet away, Andie said "Material Transfer".

Material Transfer?
Apparently a thin film from the pad can be left on the brake rotor. This can be caused from 'stabbing' at the brake pedal instead of being smooth and fluid (which is the correct way!). I must have been unusually jerky on the brakes for a few laps, and as I attempted to threshold brake as I got more comfortable/fast on the track, both front calipers/pads/rotors caused the gigantic shudder due to all the cold spots on the rotor. Scary!

Andie took me and my car out onto PA Rt. 18 and did about 15 100mph-50mph brakes. :shock: All were threshold braking (or close), some induced ABS at first, all left a least a little rubber on the road. :P

For my next five sessions and full day at Gingerman on April 19 (288 total track miles in three days!), I had perfect brakes with no fade, no shudder, and no other problems.

And EVERYONE else thought I was going to be putting on my spare rotors!

Apparently this is very common. Always rebed the pads before changing the rotors unless you are CERTAIN that you have warped rotors.

Andie is the best!
