I have mullered the bleed nipple on my bike ('they all do that'I hear you shout!). Bloody thing has snapped off,tried the usual Eazi-Out method of removing it but it's having none of it. I am reluctant to attempt to drill it out as from experience I know I'm useless at this stuff. So before I remove it to a Machine Shop for removal I wondered if there is a replacement caliper that will bolt on?
