No the drive shafts have sufficient play not to push anything towards the hub of towards the gear box. How many miles has the car done? The movement you describe above would be caused by a worn wheel bearing or a loose drive shaft nut (ehmmm, I think). In which case the rotor is never in the position it should have been hence the noise. If the car is new ... the other possibility (which is the easier one to solve) is that the rotor and pads when combined are slightly too thick. I have had pads (Lucas) which I could not fit in my C900 when brand new but I could fit any other set of brand new pads. If it helps a little. Regards Charles -- Please remove _removeme_ to reply.
