Well, first, resurfacing really means turning them on a lathe to insure that they are "true" and not warped. you are removing a few thousandths of an inch by turning them. This does reduce the mass of the rotor and does accelerate its wear for the next warping. I have only had my '05 330 for 18 months and have no long term experience with them. Oth, my 93 Acura Legend with almost 116000 miles on it has the original rotors that have never been turned. If a rotor isn't warped there isn't any reason to resurface it. This is one of the mechanics greatest and easiest ways to generate money.
If you suspect the rotor is warped have it evaluated before you pay for new rotors and the labor to change them out. Your mechanic will need a dial indicator (and the knowledge and ability to use it - duh) to test a rotor. If he doesn't have one, go to someplace that can use one. This is a ten minute test at best and I would guess that since Toyota put the word Lexus on it, the rotors are more than the cost of gold.
Bottom line? Make sure you have warped rotors and then turn them once. After that they usually are too thing to turn on a lathe.

Greetings,
I'm a newbie and joined this forum to see if someone is experiencing a similar issue that I am on my 2004, rx330 with 28k miles. After reading this string it sounds very similar. The difference is that i have a hard time repeating the brake juddering at high speed but when it does happen, it usually translates into brake juddering, steering wheel vibration and then a loss of power. Once I slow down or come to a stop, all returns to normal. I've had the vehicle in to the dealer for several issues. Is there a reason why brake juddering at high speed could also translate into loss of power? Note this does not happen often but when it does, it's frightening and the braking power is severly reduced, hence i'm very concerned since my wife drives around with my 2 year old in this vehicle. Any suggestions?
