Replacing rubber brake lines, i'm about to lose it

[Iamthewalrus]

I did my rotors/calipers/pads the other day. I want to do the rubber lines as well but I cannot for the LIFE of me get the hard line screw to unscrew from the rubber line where it penetrates the frame. I have tried for days with Blaster letting them soak and I've gotten nowhere. It's like they're welded in there. Not to mention they're a pain in the ass to get to. Does anyone have any advice or any other solutions for me? I'm about to pull my hair out. I'm so frustrated it's taking this long to do something so simple.

Only thing i can say is if you can get the hard lines loose from the combo valve, maybe replace them too?

 

[Iamthewalrus]

@K201979 Yeah that's my last resort. I really just didn't want to have to replace those too as they seem to be in good shape.

 

[K201979]

I understand. Pb blaster n maybe tap/bang the fitting with the wrench.

Make sure to use a flare wrench, otherwise you will almost certainly strip it out. Sometimes tightening the fitting first will help free it up as it gets the line unstuck from the flare nut..

@legopnuematic The crazy thing is, i started with one of those and its so tight that it turns on the nut. So now it's already a bit rounded. I've been trying with a small vice grip that I can fit up in there and with it as tight as I can possibly get it, it still spins on the nut. I will try tightening it a bit tomorrow and see if I can get anywhere.

Id try heat if you can safely

 

[K201979]

If the nut is rounded, id definately just get new hardlines

Silly question but...Do you have the vice grips facing the right direction? Some vice grips are like pipe wrenches; they grip better facing the right way.

You might try to add some heat to it but you have to be VERY careful. Don't add too much heat, don't get it glowing hot, not even close to glowing. If you don't feel comfortable doing it then don't. Last resort is take vice grips to it and replace the extra hardline. Adding heat to stuff like that is taking your safety into your own hands.

 

[Iamthewalrus]

@Frankenchevy Yeah i've tried both directions actually from different angles up in there and can't get it moving. I guess i'm going to end up doing the hard lines as well...

Did u pull the c clip from the soft line fitting and pull it through the bracket a little. Those hard lines have flat spots that sit into that bracket. Some people don't know that. If u pull it through a little, u can get a set of vice grips on each fitting. It will free up that way.

As Edward said, you need to pull the c-clip out first. This will allow you to pull the hard line through the frame. Once through the frame you can put a wrench on the rubber line and flarenut wrench on the hard line. If you don't pull the c-clip it's difficult to get the flare nut wrench on the hard line since the frame rails are in the way. If the hardline nut is rounded off, use vise grips.

I just replaced all of my hard lines and found that I had to bend my flare nut wrench for the RF caliper line at the frame. The trick mentioned above to remove the clip and pull it through is solid, and I wish that I had thought of that!

Honestly, for the cost of replacement tubing its silly not to for such aged trucks if you need to.

 

[Iamthewalrus]

Great I will definitely be trying to remove the clip and pushing it through. Hopefully I can get it off of there!
