I Broke my nipples :-)

[bikerzx7r1981]

I did it... The back caliper I soaked and soaked and soaked in WD40 and both brake nipples snapped off GUTTED.

I have drilled them out a bit at a time, I just wanted to know what to do now... do I have to re tap them or can I try and screw new nipples back in.

Hany help much appreciated

Snapping nipples?...hmm, sounds like a personal problem....

[hampshirehog]

I'd run a tap through there.

once you got the old stuff out i would run a tap through them as well but be very carefull. The little beveled end on those BLEEDERS has to fit in to the recess at the bottom very securely or they will leak and suck air.. look at a good one and youll see it is tapered at the end to fit into the detent at the bottom of the caliper housing...

It might be easier to find a caliper off e-bay for cheap and rebuild it.

I purchased 3 fronts and one rear with all the lines and nipples (bleeders), (banjos and bolts) in two auctions for about $60, and one auction the 2 fronts came with 2 sets of EBC pads.

If the nipples snapped off, to me it seems like the caliper is in really rough shape.

Broken nipples.... man this post will get a lot of attention...If you have drilled out and not damaged the seat you should be fine. It is after all a steel nipple it has the ability to deform what's there in the aluminum casting. Probably why it broke too much torque applied.Use a small wrench and hand tighten.... if it doesn't leak you're fine. Just curious did you try an easy out before drilling it into submission?

Personally, I'd drill and tap before buying a new caliper. Oh, and WD40 is not a penetrating oil.

What ya got?

I have a few spare calipers, what cha got?

[Macguyver]

I think I know the problem, ya need to get them nipples cold before they are hard enough to remove.

I would say an 1980 GS1000G.

And probably the caliper looks like this one,

Use KY instead.
