So, I was refilling my brake fluid after painting my calipers and when loosening the bleed nipple it snapped. Which is frustrating because I had been opening and closing it a week or two ago and it wasn't seized at all.
I've managed to drill and remove the old nipple and retapped to m7, the threads look ok but I won't know untill I fit a new nipple. I can't seem to find a length for the correct nipple. I mean the threaded part, because mine has been reduced to swarf. I roughly measured how deep the hole in the caliper goes, about 5-6mm I guess. I'm struggling on eBay to find nipples with the length stated.
You guys know what length of nipple I should be looking for and does length really matter?
