How to Flare Brake Tubing

Video Transcript

"DOUG JENKINS: Hi. I'm Doug. I work with 20 great guys in Saint Louis at Doug Jenkins' Custom Hot Rods, and we're going to do some work for you today on Expert Village. Now, Mark is going to use the flaring tool in order to create the correct flare for a brake line. A brake line gets a double flare, so it's a little different process here to do a brake line than other things. So we have the flaring kit here. Mark has chosen the right sized dies for it. He puts it in there with, you know, the right tools there for the right length and the right diameter for what he's doing and tightens down the brake line. So now he's chosen one that will fit in the end of the line and create the correct first flare. He needs to flare it out and then bend the end over. So this is the first die that flares it out. So the first one goes in there a little bit tight. And then with the hydraulic press there, he just mushrooms it the last little bit. And then the second step, and now, with any luck, it'll produce the right end on the brake line, no galling, it didn't split. You always want to expect them real carefully and make sure it hasn't galled or split. MARK: You always want to put the nut on first. DOUG JENKINS: Yeah, think ahead. Make sure you got the retention nut on first. You don't want to flare it then try to cram it on there."
