strugled with it untill i partially rounded the bolt on the hard line.

 

Let me start out by saying I have never done this, so take it as you will. But wouldn't vise grips work? Or will the pinch/bend the line?

 

VG's will work but then the fitting should NOT be reused. The fittings are soft metal, i believe brass, and will get damaged. So basically if you use vice gribs you will most likely have to

a) buy a new breakline assembly or
b) replace the fitting which requires cutting the break line, put on a new fitting and re-flare the end with a brake line flare. this will shorten the breakline, making life difficult.

what you need is a set of fitting wrenches, hey are shaped differently to hug all edges. A set at advance auto is bout 14 bux

 

well from doing this i can tell u....on old fittings flare wrenches suck and round out the fitting and visegrips dont damageas much as u think....

 

Using the correct tools would have prevented that.
You need a flare wrench to work on brake lines.

 

so i use the flare wrench to hold the hard line, and what do i use to loosen the rubber line?

 

buy a haynes, PS I wouldent mess with vice grips mine if you paid me

 

i have a repair manual but i dont htink it says anything usefull on that topic

 

Buy another fitting. Cut off the hardline just behind the rounded fitting. Slip on a new fitting. Use a flare tool to reflare the hardline. Done and done. Besides the hardline being about an inch shorter, it's good as new. At the worst, you may have to use a zip tie, or some metal wire to secure the now slightly shorter hardline to the mounting tab.
