266mm Caliper snapped nipple - Chris_90 - 03-05-2015
So got some 266 calipers off ash, one with a snapped nipple, I've drilled it out so I've got a few questions
One is what is the thread size of the nipple?
Any one know we're I can get some stainless steel nipples from?
And how can I make sure the nipple will seal correctly now I've drilled it out?

Pretty sure they're M7 X1 & are £2.30 each with a cap from Pug,just copper grease the threads before installing them for easy future removal.

Don't think it is m7 tried a m8 bolt in it earlier and that screws in fine so must be m8 and looking on ebay the only thread in m8 is 1.25..... All tho the bolt I used was 1.5 thread so unsure what it is

Youve drilled it out, but havent retapped the thread?

Not yet I used a bolt on the other Caliper to try the thread

Depends how careful you were. If the drill has hit the seat in the calliper, the calliper could well be scrap :/

Pretty sure these are fine thread, are you sure it was m8 x 1.5? Did it wind in by hand?

How would I know if I've hit the seat? (I bet I have

Hmmm I belive it was but your making me wonder now I'll double check tomorrow. Probably just end up with another Caliper at this rate save the messing.

Yeah unfortunately drilling bleed nipples is a right bastard of a job that even the professionals seem to get wrong fairly often - i've sent two refurbed calipers back to pagid in the last few weeks because the bleed port wasn't properly cleared.

That looks like a handy bit of kit, hmmm... Thanks, grantpipe!

Wouldn't something like this be better than drilling them out (I know you've already done it, just mean in general)http://m.screwfix.com/p/hilka-pro-craft-stud-extractor-set-8-pieces/20084
RE: 266mm Caliper snapped nipple - grantpipe - 09-05-2015
Ya could try it but the good thing with the small kit is if ya snapped a nipple again it's so easy to replace the nipple

I think the trouble is that they're for bolts where there's metal left but a bleed nipple is hollow so wouldn't really be able to grip onto anything solid & if the nipples already snapped the threads will be pretty rusted in but could give it a go lol

I believe a that nipple therapy kit is what I have on my 205 rear calipers, work's well
