Does anyone here warm up their brake line befor bending or flaring???

No never. Just use the nicoop tube , mix of copper and nickel. Slightly softer and forms beautifully, yet still rigid enough to meet safety regs.

 

Try some ni/copp brakelines...you will probably never use any other kind!

 

It heats up in both of the processes asked about, that is probably enough heat...........
I’m curious as to what a ‘buggy’ is that OP refers to.

 

Was making the brake lines on my 65 Comet . Just use NiCop brake line . Does 90 degrees and 60 percent humidity count ? That how hot it was today and the line flared and bent just like it always does.
No issues.

 

The easiest way to flare brake lines is to spend the extra money (yeah, I know it’s expensive) and buy the hydraulic line flaring tool. Mine works perfectly on NiCop and steel.

Want perfect bends and flared ends, I put a little oil on the tubing and it slides on the bender perfectly, same when double flaring.

 

Never do the heat. Also, have the SK set and use a little oil like said above.

 

You may find this hard to believe, but when I was bending conduit on jobs you had to correct for ambient temps. You'd get more 'spring back' the colder it was. On small tubing though I wouldn't apply much heat. Maybe lay it over a light...

 

Use brake fluid on brake lines, anything petroleum based is bad in brakes

I hope I don't die. I used my $ 8.00 Harbor freight double flaring tool .
It does the job and I have built many cars using the same tool.

 

Never did this but I'm going to try it..

 

I believe it has more to do with the user than the tool. The mobile tool salesman want the young kids to believe it’s the tool that makes the mechanic, time and experience has shown me that it’s the mechanic that makes the tool.

I once had a cheap double flare tool where the double flare button was not on center. The counter sink and pin were not concentric. How could that even happen?? A lot of scrap tubing before I figured it out. Now, I look at cheap tools as a parts kit. Keep what works and rebuild the rest.

 

I use a spritz of wd40 on the anvil and die when flaring also. Never tried it while bending. I would think it would help if using a bender that did not have roller bearings.

 

That's what SHE said....

 

Nope. not even using a cheaper amazon special flaring tool. clean the ends good, get the clamp tight let the tool do its job.

 

if you need to heat the line then eat a hell of a lot more spinach.

 

no heat, ever, but i do take a file and slightly bevel the outside edge of the tube. this helps the tube start to roll over in the die for the double flare. not really a full bevel, just dress the edge a bit. it helps

 

The Imperial flaring set I bought years ago actually recommended that in the instruction sheet.

 

Nicopp makes life a great deal easier, however one thing I would caution you on,

when using Nicopp lines be careful about tight bends next to the fittings.

I did this on my wifes Model A and after about a week or so the brakes bled out from a tiny hole that formed where the fitting was hitting against the line.

I ran another line and have had zero problems since, that was over a year ago.
