O is that what it's for!! Now I feel really stupid haha
Well now it's too dark so it'll have to be done tomorrow now.....
I say ' Some say' as we never seem to have had a definite YES that is what it is for.
(not so dumb,--------it has been asked lots and lots and lots lots more times on here before you asked)
It also has the job of helping to remove the discs when they stick to the hub, you undo the bolt, remove the spacer and wind the bolt back in and it pops the disc off .
Haha that's a good idea and a useful one to know.... Little hidden trick with it lol
I'll keep it in mind when I'm changing my discs
Thanks
