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

Cheers guys ill give your ideas a go. Thunderace they may well be on your doorstep soon for that price, cheers.

If they are M7 threads, you need a 6.2mm drill And you need an M7 tap, not a size in frequent supply domestically.

Just looking at the drill sizes, when i sheared them off i used an 8mm drill bit, have i now shagged em?

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.

i have a set of calipers, £37 delivered, i sold a set last year for £30 delivered only to discover at the postoffice it was £7 to send

will need an over haul, took them off bike and then borrowed them to del, i have 600rr calipers and have no intension of going backwards.
