The movement should be there, but it will be small. When a bobbin seizes you effectively get a high spot which could account for the uneven pad wear you mention, and possibly the noise as the pad tries to move the disc and vice versa. It's maybe that you have a number of stiff bobbins causing the disc to creak as they all try to align. try rotating the bobbins and see if you've got one or to that don't move.
Take a photo of your disc/wheel and some one might go, they are --------- ------------- discs or not, just a idea.. brian.
Could be on the road to recovery. I nipped home at lunch time and had a play with my bobbins!! There is movement when I push the disc laterally both ways however on the side in question one bobbin felt a little stiffer than the rest this could have been the cause of the squeek too. I manipluated all of them and now the wheel spins more freely, I did not have time to check if this has gotten rid of the visable warp.
Well 1st prize goes to the man how mentioned the bobbins, I spend some time last night cleaning each bobbin making sure they all spin freely etc. The disc with the warp still has a very very very small warp but IMO on enough to warrant replacing. Previously with the bike on the stand I was barely getting 2 full rotations from a good hard spin and now im getting nearly 4. A road test is needed so all being well I can this weekend
Interesting you saying you get nearly 4 rotations now Mr C , Ive never had more than 2 even if I pull that wheel like I'm pulling a rapist off my wife, and yet my discs arn't warped nor do they make any kind of noise at any speed. However the pads do appear to be permanantly touching the discs ,if only ever so slightly ! is this the norm.? The only noise is from the hiss of the brembo's when braking.
The pads will be in near permanent contact with the disc, the pads will get ever so slightly pushed away by the run out in the disc, so all sounds normal. So either Mr C is a lot stronger than you, or he's lubed the bobbins with grease which is now coating the disc making it spin more easily ( only joking, although I did have a mate who packed a rear drum brake with grease to stop it squealing)
