Replacing metal brake line that runs across the rear end
Well I started this job like a good little mechanic with a Snap On tubing wrench. (I am working on the end that connects to the backing plate for the drum) When I rounded the flare nut off I went to a pair of 5 inch vice grips. Given the angle I cant really get a good bite on it. I have thought about cutting the line off with a cut off wheel and using an ease out but I feel like I might be opening a can of worms there. What have you guys done. I am ready to dive this thing and not having breaks is kind of a set back.

Re: Replacing metal brake line that runs across the rear end
You can try heat but I suspect that you are going to end up replacing the wheel cylinder.

Re: Replacing metal brake line that runs across the rear end
Yeah, they are about $5, and if yours are rusted so bad you can't get the lines out, it may be time to replace.

Re: Replacing metal brake line that runs across the rear end
heat or a new one just remember NEVER SIEZE you never know who the next JA to take it apart might be..maybe you...old man told me that and he has been right to many times
you might also try cutting the line off and putting a 6 sided socket on it....even if you have to goto a MM size and give it some love to get it on Last edited by Hottrucks; 09-02-2009 at 08:32 AM. |

X2. A couple of $$ but a piece of mind.

Re: Replacing metal brake line that runs across the rear end
Wow... Thats the first time Ive heard of a Snap On brand tubing wrench rounding off a fitting. Yea, Id replace the wheel cylinder. I wouldnt personally use anti-seize compound though... might not be good to use that on the hydraulic brake system.

Re: Replacing metal brake line that runs across the rear end
Just cut it out and replace the wheel cylinder and rear tubing. You can get the tubing cheap and go to autozone for a flaring tool (free rental).
Or get a replacement line from a company/vendor (LMC, inlinetube etc..)

Re: Replacing metal brake line that runs across the rear end
I got my tubing from LMC and it worked well, just needed a few minor adjustments.

Re: Replacing metal brake line that runs across the rear end
You say you have new brake line, is it a prefabricated piece?
If not, and you are making a new line, please make sure you use double flare on the ends. When I redid my truck, I did not (just single flare), and when I bled the system, each single flare leaked. I had to remove all lines and double flare and reinstall..... Lessoned learned. |

Re: Replacing metal brake line that runs across the rear end
Just make sure you only take apart one wheel at a time so you have the other side to reference when reinstalling and a digital camera is your friend, take a bunch of pics during the tear down for reference later.

Re: Replacing metal brake line that runs across the rear end
Funny to find this thread, I was just about to post a rear brake line question! On my 72 Cheyenne 4x4, I just replaced the left wheel cylinder. Putting on a new line I now find the wheel cylinder end is 3/16" and the end at the pumpkin is 1/4" Should I use 3/16" line and adapt at the pumpkin or use 1/4" line and adapt at the wheel cylinder? The factory line I removed actually had different fittings on each end. Thanks in advance!

Re: Replacing metal brake line that runs across the rear end
I cut the brake line with some dikes and used a socket to get the flare nut out. I wish I would have thought of that a week ago
