MOT Problems - Trashed front wheel bearings!!

Ive had the bike MOT'd recently and it failed for poor front wheel bearings so i bought some new ones and replaced them myself. I couldn't believe the state of the old bearings - totally worn, bone dry, rusted and full of debris. One bearing snapped in two parts on removal!!

I got an advisory caution for warped discs on the MOT, so im on the hunt for some nice used ones.
