Bleed nipple disaster
Hello. I am refurbishing some rear brake callipers that I have spare and intend to paint and fit to my spider. Now, both Bleed nipples were stuck solid and I tried heat, freeze but still would not budge, I sheered one nipple off and the other I cut off.
I drilled through one of the bleed nipples with no problem, got to the bottom carefully and now I can see the seat where the bleed nipple sits, I just need to tap the thread and I am all done.
The second one however didn't go that well. as I was drilling to make the hole slightly larger (before using the bigger drill piece) the drill snagged and snapped in the hole. I had to saw off the drill bit as I couldn't remove it or get it out. I tried to punch a centre in the sawn off drill bit to align the bigger drill and went on my way. Unfortunately when I have drilled, it has been offset quite a bit to where the nipple sits.
How do I repair this? It looks like I need something like this but I am not sure.
