Before i break it, can someone help ?

[1peter]

The rear brake bleed nipple is rounded off and i don't want to break it while trying to get it out using vice grips, any ideas ?? Any help appreciated.

Did you try liquid wrench or wd40 yet?
Could probably try to heat it up a bit with heat gun or blow torch depending upon whats near it.

Thanks, I thought about heat, don't know what liquid wrench is ? I have sprayed it with WD40.

If you try the vice grips and break it, easy outs will get it out no worries, and since its rounded off you'll need to replace it anyway

To further on both previous comments-

WD40 is pretty poor as a penetrating oil. It was never actually designed for that. As such, you may notice that last year they started offering a line of 'specialist' products that I believe include a penetrating oil however they aren't all that common yet. Liquid Wrench is another brand of penetrating oil that has shown to be one of the better products in testing. Kroil and PB Blaster are others, though I think Liquid Wrench probably is a bit better than either of them as well.

If you do go with heat, you may want to flush all the fluid out of the system since you'll likely cook it. At least do a good bleed to flush the caliper.

Lastly, I wouldn't worry too much about destroying the bleeder with vice grips. Yeah, they'll likely mangle it pretty badly, but you're going to replace it anyway, right? And even if they totally round it off, a bleeder would be relatively easy to use a bolt extractor on since it's already hollow down the middle. BTW, if you have the oportunity/need to use an extractor very often, look into something other than the EZ-Out brand stuff. The tool truck guys all offer things that work much better than the typical parts store things, but of course they charge accordingly.

Because you are replacing it anyway, a good swift blow straight down on the top will usually break free the rust and corrosion on the threads. (mangle the tip a bit) If you can't get a swing at it, use a drift of some sort, make sure you go straight in line with the bleeder or you'll snap it clean off. Then use the liquid and vise grips to remove it. Heat works well if you can keep it very localized.

Thanks for all the input, I actually used a product called INOX which is better than WD40 but i will look into the other brands you guys have mentioned. I'll leave that for a while, try the multigrips and if that doesn't work I'll try the other suggestions. Thanks again.

Hey man - I'm in Brisbane (Stafford) if you break it off and need an easy-out. Just shout out if you want a hand.

I bought a set of those things to pull some rounded bolts out of a Mopar water pump - absolutely fantastic, but not cheap. I'm not sure they go right down to bleeder size though?

I've always had good results with parrot/speed wrenches on rounded bleeders too - It ruins what's left of the hex, but if it's already had two flats rounded off it should be heading for the bin anyway.
