Thanks for all the quick replies.
Chris, I never really used those wheels that much so I don't think they are worn.
I just tried rubbing alcohol and scotch bright. It is better but there is still some pulsing. The pads work well with the other wheels but I will try that next.
One other question specific to those wheels if I may.
I am having a very hard time mounting tires to these wheels. As careful as I am I just damaged a new tube. It almost seems like I am on the verge of ripping the tire, that is how hard it is to mount them. The tires are Vittoria Tecno pro, if that makes a difference. I have never had a problem mounting other tires and wheels.
Any tips or info would be greatly appreciated.
Thanks again, Rich
