HI I'm trying to replace my driver side brake line and I'm having a bit of a hard time, I was trying to use a regular 3/8 open wrench, but I feel like I was just stripping it, so I got a flare nut wrench and tried using the 10mm one but doesn't seem to fit as tight at the 3/8, so I went and bought a 3/8 flare nut wrench and now that I tried using it, I can get it around the stupid nut or brake line! What the heck am I doing wrong?! Anybody have an easy way to get that **** off??? 93 jeep grand v8 just in case anybody needed to know

 

Okay, here's the deal. When you used the open end wrench, you made the tube fitting out-of-round. Now the flare nut wrench won't fit because the flare nut is misshapen. At this point visegrips will work. AND you'll need another flare nut, unless you are using premade lines. I would suggest using copper-nickel tubing because it's easy to work with and won't rust.

 

Awesome thanks for the speedy response and advise
