Lately I have noticed some vibration when stopping from speed. I assumed that it may be time for a brake job including resurfacing the rotors. However, this afternoon I was visiting a fellow NSX club member who is very knowledgeable about the NSX, especially in the mechanical area. He does most of his own maintence and any related necessary work. I mentioned my brake issue and he has a different take on it.
His extensive experience, much at tracks, indicates that it is very rare for the NSX rotors to become warped. You almost have to get them extremely hot and then immerce them in water - doing this several times - to get minimal warping. Another way is to drive very hard for example at a track event and when you stop apply the hand brake tightly (which is a no-no by the way).
He believes there is a more likely explaination of what is going on. If the pads have life left and it is the vibration issue bothering me he suggested that I take the NSX to say 80 MPH and brake very qucikly - (and do this with no one behind me goes without saying). I should do this about four times and each time I will probably notice the vibrations getting less and less. It seem that the phenomen is "brake pad transference", that occurs since I rarely drive my NSX hard. Over time the brake dust can settle onto and into the rotors so that the surface becomes contaminated and uneven. While turning the rotors will alliviate the problem, it may be solved by doing the heavy braking thing. On ocassion the brake pad dust has so accumulated over a long period of time with chemical reactions, etc. that heavy braking will not be a remedy.
I am going to give it the heavy braking test, but am curious if other NSX'ers know about this and tried it already.
