Success!
removing this much metal
means wheels now turn!
I'm so grateful i bought a dremel a while back. would have been a pain in the arse to cut with a 4inch.
i also got some new 810 calipers. they are different to my current 810 ones though, the pad is shorter. will give them a freshen up and get them in soon.
and she finally got a well needed wash!
thanks for the help guys
