ben7 Posted August 24, 2006 Share Posted August 24, 2006 I spent last night fiddling with my nipples on the front calipers, bleeding the brakes. I managed to overtighten one of them and snap the end off, leaving the screw bit tightly in place. I'm not sure how these things work. I would presume that because it sheared off due to over tightening, it will not leak (be safe), although the hole running through the centre of it is still visable. I appreciate that I'm buggered when I next adjust/change my brakes, but I have a track day looming this weekend and want to get out. Ben Link to comment Share on other sites More sharing options...
susser Posted August 24, 2006 Share Posted August 24, 2006 Don't want to commit to anything that I may later want to rely on in court (as they say). But, The seal is actually the tapered part of the bleed nipple sealing off the hole. If I was in your position, I'd be quite happy to use it, if, as you say, the nipple is tight.

susser Posted August 24, 2006 Share Posted August 24, 2006 OH ❗ I assume the nipple is still in the hole and only the bit that protrudes is broken. Link to comment Share on other sites More sharing options...
ben7 Posted August 24, 2006 Author Share Posted August 24, 2006 Yep, the protruding nipple has broken off, but the the other bit is in place. I've applied the brakes hard and it's not leaking so it looks ok, I just wanted to check that it was indeed the tapered bit that seals it and the visable hole in the centre is actually closed from underneath. Any ideas how I can get the bottom bit out? If I drill it, then there is the risk that I'll get bits dropping into the caliper. Could these be flushed out when I bleed the brakes again?

stevefoster Posted August 24, 2006 Share Posted August 24, 2006 I'd try to remove the snapped of bit before it gets road grime etc on it and it becomes even more difficult to remove over time. Tip is don't bother with screw extractors. They don't really work very well. Drill a small suitable sized hole for a small torx bit. Large enough for the points on the torx to have something to bite into. Gently tap the torx bit into the hole and undo the stub. Be very careful as a brake calliper is a delicate thing. Might be better to remove the calliper and get it on the bench to sort out. I had 8mm bleed nipples on a old Honda - they were pretty fragile. Above method worked a treat. 10mm bleeders are more robust but still don't need overtightening - just nipping up really Hants (north) / Berkshire club here Area meeting pics here My Racing here Link to comment Share on other sites More sharing options...

ben7 Posted August 24, 2006 Author Share Posted August 24, 2006 Steve, I had often wondered what those little funny shaped things were that came with socket sets Anyhow, didn't need to drill a hole in the end, torx bit gently inserted with use of hammer and screwed staight out Thanks once again, Ben Link to comment Share on other sites More sharing options...
Paul McKenzie Posted August 24, 2006 Share Posted August 24, 2006 Ben, Just remember these things don't need to be boll***ed up V.light tightening (as soon as you feel any resistance )just a tiny (sixteenth) turn with an open ended spanner is sufficient to seal the nipple.
