My GF's 2000 VFR with a Superhawk front end has a high speed (above 60 mph) brake shudder. Below 50 or 55, I can't really feel it though. About a year ago I rode it and felt it, so I pulled everything apart, made sure the front end was tight and torqued it all to spec using the Honda steps. She said it was better (I didn't ride it again though) and never said another word. Well, I rode it a couple of weeks ago, and it felt worse now than it was a year ago. Apparently it has been there a while but she never said anything. Maybe it just slowly got worse with time. I bought a dial indicator and set off to measure the rotors. Found one about .010" and the other about .004" runout. I used a cresent wrench to bend them a little back to straight. Seems both are back to about .002"-.003" but I still get a shudder. Spec is .012", so I should be well within that limit. Since the bike has the Superhawk front end on it, I also played around with the calipers a little. They weren't exactly centered on the rotors, so I bought a few washers and tried different ones to get them more centered on the rotors. They seem to be pretty center now, but it didn't change anything. What am I missing here? Do I need to pull the rotors off and clean the surfaces using something like this? http://www.amazon.com/Flex-Hone-Flywheel-Surface-Silicon-Carbide/dp/B00063VDR0/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&colid=1D22E2FJV7TF4&coliid=I2PEVBKHTUQYBY Maybe pull the pads off at the same time and sand them down? Anything else to check or do?
