Rounded off bleed nipple?

[GrumpyGuts]

Hi,

I'm trying to unscrew my bleed nipple on the front caliper to drain the fluid, but the nut has been rounded off by the tosser who had the bike before.

Could anybody lay down some suggestions on how to turn the bastard? Tried the mole grips but it looks like I'm making it worse!

I've ordered a new nipple so I just need to get this one out.

Thanks

Take caliper off, remove hose, apply some heat around the nipple housing, then apply some lubricant, tap it gently around the housing of the nipple then remove with mole grips

No.

I managed to snap mine doing the same. I did try and drill out what was left and made an arse of that so in the end i bought a banjo bleed nipple.

Worth paying the extra money for stainless steel ones if you go down this route.

Use a socket before it rounds all the way off.

If it's too late for that, file a new head onto it so you can get a spanner on it. i.e two flat bits either side

If it's totally gone, dremel time. cut the tip of the bleed nipple off, cut a flat slit into the bolthead that remains, then undo it like a flathead screw, possibly needing a tap with an impact driver to get it cracked off if it's been overtightened.

If you have to remove the banjo bolt it may be a good excuse to fit braided lines if not already fitted to the bike.

Obviously more expense but an investment.

Please post if/how sorted

Done! The socket idea worked, just had to quickly put the pipe over the nipple whilst it was still leaking.

The fluid was BLACK. Looked like raw sewage!
