Pics inside/ Early Classic Stainless Hoses

[Dub J]

Just installed my new Early Classic stainless steel brake hoses and was wondering if anyone had to grind their calipers like this to make their brake hoses run properly?

I had to grind a little on mine when I replaced the calipers with a reman pair. I'm not sure where the compatibility issue came from because the discs were installed by a previous owner. I even tried swapping the lines side-to-side, but as you probably found out too that does not work... Grinding the calipers did the trick.
