I mounted on a pair of wheels. No difficulty. All good.

Check the part number marked on your hub and the type of disc mounting. Your wheel must have a Centre Lock system and be compatible with an external-clamping nut.

Yes, it can be used with Centre Lock discs from other manufacturers, provided that the mounting system and dimensions are compatible.

Yes, provided it shows no signs of wear and tear and its thread and contact surfaces are in good condition. If in doubt, it is best to replace it.
