Hi, im at about 80% now on the trackbike build, tried bleeding off the calipers today and both nipples were seized so ended up shearing both off. Realisticly what is the best option, been looking on flee bay at a company that sells recons with a part ex of your old, so far this seems the best option, or is there an easy fix? Dont fancy drilling and retaping!! Help would be much appreciated

If you send them up to me I can sort them out for you

£10 per caliper plus return postage. Should have them back to you within a couple of days of me receiving them.

Soak them in plenty of releasing fluid and use a screw extractor and they should come out.

Apply some heat too if your having trouble.

drill them out use a 5.5mm drill bit keeping in line then run a good tap down to clear threads. time and patients is very much needed

If they are M7 threads, you need a 6.2mm drill

And you need an M7 tap, not a size in frequent supply domestically.

Have you drilled into the caliper with the 8mm bit?

If you have they're pretty much fubar, an M10 nipple (used on trucks) would be way too big.
