Help With Using Flaring Tool on Brake lines
Posted: Thu May 10, 2007 6:12 am
I almost have the brake lines done on my Sunrunner, but one of the precut lines needs to be trimmed down and the fitting replaced. I have a flaring tool kit and was practicing on some scrap brake line, but with little success. It seems my flares always end up lopsided. Now reading the instructions I need to cut the tube straight, not a problem with a tube cutter, de-burr it, not a problem with a de-burring tool, chamfer the outside edge (I had not noticed this instruction and wonder if that is the problem) but I am not sure exactly what needs to be done in this step.
Then put the tube into the flaring bar at the correct height based on the flaring adapter, insert the flaring adapter and put the yoke over it and crank down (this is where things go wrong is the correct adapter size 3/16"?) then take it out, crank down the pointed part of yoke to finish the double flare.
So, what should the chamfer on the outside edge be like? Any other help? I really want to get this job done as our Mazda Protege is running rough enough that I wouldn't want to go out in it. So we are down to the van only. That gets a little expensive on gas so having the Sunrunner up and running again would be great.
