flaring brake lines

nazgulMember

hi all

i needed to make a set of brake lines, so i bought a flaring tool at the local auto parts store. when i double flare a tube, the inner surface of the flare has a series of small concentric rings that match the tooling marks on the tool anvil. these rings are not present on factory made flares.

will the concentric rings eventually cause a leakage problem, or will the fitting draw the tube up tight enough and deform the concentric rings enough so that brake fluid leakage is not a problem??

i just hate to go ahead bend all the lines, bleed the system and then find out i did a boo-boo.

thanks

It shouldnt be a problem as long as the rings are not too deep. Just in case, you might want to put a steel flare fitting in a bench and tighten each fitting well before installing. A small amount of tube rotation while tightening will polish the flare.

By the way, you probably spent 50 bucks for your flaring tool. The factory stuff is done on multi thousand dollar machines.

nazgul,

I made the entire brake system in my MG restoration. I found the low cost brake flare tool almost imposible to get a good flair. I bought a better tool from Eastwood and it was worth every penny. I did not get a bad flair with the tool and it could easily be used on the car. The flair itself was thicker and more sound:

Ridgid makes a good AN flaring tool if anyone decides to use stainless line. It has a breakaway system and automatically burnishes the flare. I imagine they make a good double flaring tool as well.
