The stainless brake lines I ordered arrived today and I was very excited to install them but I can't loosen the screw/nut that holds the stock brake line to the main line (chassis side). Tried soaking it with PB blaster for 2 hours but still it wont budge. The edges of the screw is starting to get "rounded" (don't know the exact term) so I stopped trying as I don't want to completely ruin the screw. This is on the rear driver side. Have not tried the other sides yet.

Any advice or idea are highly appreciated. Pleeeeaase...help.

 

hated when that happens. you could try torching it then use vice grip to loosen that. good luck

 

You gotta use a flare nut wrench so that it grabs more sides of the bolt than a standard wrench.

get a flared wrench so you don't round off the nut anymore. don't use a torch unless you really have to, cause you might warp some stuff. i'm hoping the flared wrench plus a little muscle will do it for you

 

I'm using the flared wrench but all it does is eat on the nut same with the vise grip. Don't know what the nut is made of but it's so soft. Don't want to torch it yet. Does the brand of flared wrench make a difference? As I'm using the cheapo ($7) Autozone one.

Tried loosening the rear passenger side but same thing happens.

Thanks for your replies, guys.

 

+1 on the flared wrench. I don't think brand matters either, as long as it's functioning correctly. This might be obvious, but make sure you have the right sized wrench.

Mine was tough as well, but finally gave in after a bath of PB blaster. Seems like yours is being stubborn. Goodluck.

 

Mine was a bi*ch to get off too, I had to use the flare wrench, and vice grip the flare wrench over the bolt and then heat it while my friend twisted the wrench... (I put the flare wrench on the bolt then vice gripped the two ends of the wrench so it would hold the nut better)... They were a real pain, I was scared though because I noticed a little fluid coming out so I had to get it off and replace it, one way or another...

 

@Thrilla, I'm using the 10mm flared nut wrench.

@bucherj, did the vice grip really help in tightening the wrench's hold on the nut or it's just the heat that loosened the thread? Can't do the "vice grip over the wrench" as I got nobody to lend me a hand.

 

If you are into pretty then be warned, this makes a dog's breakfast out of the hex. But, it works every time. The fittings are soft steel so that they can deform and seal. What I am talking about is a small pipe wrench. The one I use is 6 inch. It will work on the hex or when the fitting is completely rounded. I don't even bother using a regular wrench for this job anymore.

 

I'm done trying and it's so frustrating. I'll just take it to competent person/shop next week.

Thanks for all the inputs, guys.

 

I was gonna say, use an impact gun on the lowest setting on it if you have air tools available otherwise take it to the shop. No use in breaking stuff and buying more and more stuff trying to save yourself a buck or two. Good luck with that though!

 

^^^ I'm not sure what you are talking about but I don't think you can use an impact gun for the brake line nut. Trying to save a buck is not the primary reason I'm doing it. It's the fun I get in wrenching my own car that drives me to DIY simple mods. Let me know if you need to change your timing belt. Maybe I can lend you a hand

Thanks

 

i just used my 1/4 impact on a Camry today at work cause it seized up and the banjo bolt wouldn't come out. haha. it worked for me, so iono...

 

I have no problem with the banjo bolt. My problem is with the nut on the chassis side (which I stated in post #1). Can't use an impact gun on it.

 

oh dang! i totally missed that one. my bad bro.
