datzenmike Posted October 3, 2016 Report Share Posted October 3, 2016 You better get or borrow a camera if you're going to ask more questions. You need a correct size, brake flair nut wrench like this so the damage does not get worse. 1 Quote Link to comment
Scgreen620 Posted October 3, 2016 Author Report Share Posted October 3, 2016 I have the flare wrenches it's a size 10mm the wrenches don't even fit on the nut that's how bad it is I will post pics 1 Quote Link to comment
datzenmike Posted October 3, 2016 Report Share Posted October 3, 2016 Well replace that with a pre made length and bleed the brakes. 1 Quote Link to comment
flatcat19 Posted October 3, 2016 Report Share Posted October 3, 2016 If you can use a flaring tool properly, you can cut the ends off and replace the flare nuts. You need to be good at this as you will be shortening your lines in the process. If you fuck up more than once you will probably be needing to replace entire chunks of line. Don't lie to yourself either with this. Don't scab your brake lines together. Do it right. 6 Quote Link to comment
spdcrazy Posted October 3, 2016 Report Share Posted October 3, 2016 and while you are there, check and or replace your rubber lines. often overlooked. 4 Quote Link to comment
Scgreen620 Posted October 3, 2016 Author Report Share Posted October 3, 2016 All sound like good ideas .. Will try that I'll buy a short length of hose to practice 1 Quote Link to comment
flatcat19 Posted October 3, 2016 Report Share Posted October 3, 2016 Best tip for flaring...the die that holds line to be fabbed, that thing needs to be tight. You can't comprehend how tight I mean. Fucking tight. I can't explain that enough. That it the key to perfect flairs. And doing that in the car is super tricky. 4 Quote Link to comment

Scgreen620 Posted October 3, 2016 Author Report Share Posted October 3, 2016 Won't me tightening the nut make it tighter? 1 Quote Link to comment
Scgreen620 Posted October 3, 2016 Author Report Share Posted October 3, 2016 Wait where do I get new nuts or what ever their called 1 Quote Link to comment
flatcat19 Posted October 3, 2016 Report Share Posted October 3, 2016 If you don't tighten the die, the line will slip when you press the flare into it. Every flare you try to make will be garbage. 2 Quote Link to comment
KoHeartsGPA Posted October 3, 2016 Report Share Posted October 3, 2016 Yes yes and yes to what gato ^ said, get to practice BEFORE you go do your lines, buy a piece of brake line at auto parts store and start practicing, you will thank us, and yes they do neeed to be fucking perfect, your safety/life depend on it....so....practice your flaring skills, and don't buy the cheap flaring kit either! 1 Quote Link to comment
mklotz70 Posted October 3, 2016 Report Share Posted October 3, 2016 This might help you get started. Most car parts stores will have the flare nuts or they can order them. They'll also have the premade lines. If you can find one about the right length, you won't have to do any flaring. 2 Quote Link to comment
datzenmike Posted October 3, 2016 Report Share Posted October 3, 2016 Or buy pre made lengths and bend them into place. 2 Quote Link to comment
Doctor510 Posted October 4, 2016 Report Share Posted October 4, 2016 Most big box parts houses carry that stuff, make sure that you get the proper metric stuff, thread is M10x1.0. IF they are SAE (Merican) 3/8" x 24 1 Quote Link to comment
Scgreen620 Posted October 4, 2016 Author Report Share Posted October 4, 2016 Their called double flare correct! Ahhhhhh! I feel smarter already I heard autozone lends them thanks guys 1 Quote Link to comment
datzenmike Posted October 4, 2016 Report Share Posted October 4, 2016 Geeeeez. Measure the length of the old ones with a piece of string and buy them! Get same length or closest over size..... $5 or $6, less for the short side, already made perfectly. Just bend into shape around a baseball bat and put on. Brakes! The single most important safety device on your truck. I'll lend you the $8 to do it right. 1 Quote Link to comment

flatcat19 Posted October 4, 2016 Report Share Posted October 4, 2016 Go to an auto parts store and just get the $20 kit brand new. You need a brake tubing bender too. 2 Quote Link to comment
