Brake Line Nut - Not Undoing

[ODYSSEYGTR]

hey guys, having a bit of trouble right now getting the brake line to unbolt from the caliper. its a 10mm nut but just seems to be strip over when i try undo it,

possibly shitty spanners i have but any suggestions? thanks. can provide pics if necessary

Is it just spinning or have you rounded the hex head off?

rounded its alright, only rounded on one bit of the nut, so i undid it further up the line and then took it off and got around the other side.

worked a treat ahah, not keen about putting it back on, will probably source another.

Always use flare nut spanners when doing brake lines.

+1 for flare nut spanners

brake lines are often aluminium which is soft.

a 10/12mm flare nut spanner is ~$12 at Veks tools.

Never heard of veks. Where they at? Cheers for the heads up. Will have to invest in some

lots of brands make flare nut spanners. I got some KC tools - they are sweet for cheap. Make sure they are derived from 6-point spanners not 12-point.

For flare nut (and open ender) spanners its worth spending the dollars to get a good brand IMO. I have some KC flare nut spanners and while they're nicely made i sort of wish i'd gone kinchrome or equivalent. For ring spanners or sockets i'd imagine the KC stuff would be great.

www.vektools.com.au - i think i got my KCs from there too.

And you can get away with say two pipe or flare nut spanners [covering 4 sizes] and they will fit just about every size you will come across in the auto world. So not a big expense really. I have Dowidat ones, top shelf stuff, had em for a while.

what are the options once the nut is rounded off with a flare nut spanner?

[tridentt150v]

probably a vice grips or a small plumbers wrench with the serrated teeth?

there is a tool that I've got that is similar to those and locks on to the nut end, strangely enough, I think its Dowidat as well. I'll have a look when I get home, but I reckon several tool makers would have something like it. Its a butchering tool for when all else fails.

The other tool that comes to mind is a stud remover, but you'd have to have the other end of the pipe undone so you could slip it over and down onto it because these tools are not open ended.

When one of my turbo lines was just stretching the KC flare nut spanner apart and rounding off the edges, i just cut off the pipe off so i could use a socket, and it came out easily. I figured it was already stuffed enough to warrant replacement, so no problems in cutting it off.

I have used hose spanners for brake work. You usually end up rounding the nuts anyway. The are better than open ended spanners buy not by much.

Now I just use vice grips for undoing stuff. Irwin have a huge range of them. Find the right size with a straight end & you will be fine.

one a brake line nut is rounded off you are in trouble....you need to cut the pipe, replace the nut and re-flare the brake line...

much dicking around it would cause
