Bearing numbering is not entirely 100% universal. Usually it is American designs that are out of step with the rest of the world. However, a reputable firm like BSL Brammer, for example, will have no problem telling you what you need if you quote the numbers.

thanks all for your help, i have a shiny new bearing in there now (aparently its the rear wheel bearing of a honda car of some sort - mechaqnic also sends thanks for all the details!)

unfortunately i am now in need of a front brake disk, boo!!

Why dont you clean your own with brake cleaner and steel wool, then use Braking (the brand name) pads?

ah if only it were that simple, the cut outs that locate on the little square washers that hold it in place are out of round....or more acurately out of square, disk is to put it politely buggered!
still stops like a bastard, but you can actually see it move slightly if you rock it at stand still, the mechaninc wasnt really happy giving it me back

I don't understand that. What means "out of square"? The rotor is intended to move on the floaters.I never heard before (but that doesn't really mean anything) about a rotor failing before the floaters failed. Do you have some picts?

yes "out of square" does sound a bit odd doesnt it, basically.....
the little square (with rounded corners?) bits that sit in the locator notches on the disk (im really not explaining very well am i?!) rounded off, they have since been knocking backwards and forwards in the notches and have stretched the notches front to back. so the disk still moves in and out slightly as it should (being a floating disk) but now also rocks back and forward (should that be clockwise and anticlockwise) like it really shouldnt.
still nothing that a new disk and fitting kit wont solve! (gulp!)
i dont have any piccies at the moment, as its all still attached to the bike, but when i take it off i will take some and try to work out how to post them.
