The pads have plenty left on them but I'm not sure if its a good idea to go throught the trouble of swapping rotors and leave the pads in. I have a set of new rotors sitting in my office so it would be nice if I didn't have to worry about ordering the pads but if you guys think its not a good idea to keep the used ones in, then I might as well place an order.

Change the pads. What pads were they?

Sometimes pad material buildup on the rotor can give a feeling like that. Run her up to about 150 and stand on the brakes to burn that stuff off!!....:-)

Mine get lumpy every once in a while...

make sure noone is behind you first, though. ;-)

I'm pretty sure they are PBRs

During slow stoppage I can feel the wheel rotation through the brake pedal. Things get much worse when the brakes are heated up and during high speed stoppage -> front end rattles really bad with lots of shake through the pedal and steering wheel. Feels so bad I almost don't want to drive the car. "almost"

lol good point

YOu could check the run-out to confirm. Doesn't sound good. What brand rotors?

JustJeff

Hmmm, heat transfer to the rotors?

I used Zimmermans X-Drilled on my old A4 and was very happy. I guess TT is another beast. I have a set of brembos which will be going on instead. I'll also try a different pad. PBRs which went on with Zimmermans still look clost to new one year later. Maybe they are to tough and hence overheat the rotor. I'll try to go with a different pad this time around.
