Had to. I've never had to before on other cars, but this time, I had to use teflon tape. The lines were leaking through the threads with the goodridge stainless lines. I'm disappointed in that, but I made sure the tape was installed in such a way that it cannot get into clog the fluid.

Finally got it bled and done and it feels good.

 

you stuck a band-aid on defective brake lines if you ask me....not trying to be an ass, but you should really replace the defective lines. maybe you got a bad batch....are you sure they didn't quit leaking because you uninstalled and reinstalled them better when you applied the tape the 2nd time?

 

nope, because after the first time they leaked, I removed and reinstalled them again, the same way I did each time. Finally with the teflon, they're fixed.

I've already gone through almost 2 bottles of motul fluid thanks to these lines. Now that I've got 'em working fine, I'm not going to screw with 'em anymore.

 

fixed

reason to NEVER use teflon tape is because if a piece of tape ever get lodged in the line, you will lose brake.

 

I'm pretty sure the brake fluid would eat the teflon tape anyway.. i'm not sure about teflon causing a brake failure...

 

No, I did not overtorque. There is no overtorquing the portion I'm talking about anyways.

 

My brake hoses are made of teflon. ("Stainless steel" hoses are teflon hoses with a braided stainless jacket.) Brake fluid will not eat the teflon tape.

But as was pointed out earlier, the seal is not the threads, it's a compression seal. So there is no reason to use tape, and it would never touch the fluid anyway.
