Brake Line Double Flaring

    Good write up. I’d only add the following

    Picture #2: A drill bit or deburring tool will do a better job of reaming the brake line. The punch will just roll the cut edge over flat.

    Photo #3: Don’t forget to use some kind of solvent or brake cleaner to blow out the lines after you’re done filing. You don’t want metal flakes in your brake system when you’re done.

    First, very important, purchase a quality double flare tool. Cheepoos from Harbor Freight wont cut it. Excuse the pon.
    Between steps 1 & 2, I file the end of the tube at 90* to square the end of the tube.
    In step 10, I don’t flare to the max. What I want is just a little more flare available, and let the connection do the final little bit of flairing to make a positive seat. Experience has taught me that this step has far more success than flairing to the max where the flare can’t yield any further when the connection is made and torqued.

    Sorry, also, at step 9, look very closely at the first flare. If it is not perfectly square with the tube, cut it off and start over.

    Great write up! It was very helpful and I did use a cheap set from Harbour Freight, I just put the entire tool in my HUGE vice to really hold the flaring tool in place. Thank you admin for all of you effort in making these accessible!
