Tips on flaring brake lines

Any tips on flaring brake lines? How do you get nice clean flares?

Thanks, T-Bucket Bob

 

First use a good tool! I use a Snap-On I have had for 40years nad have no problems. I think Eastwood has one for about $150 that a friend has and it is sweet!

 

The tool really makes a difference, but also, a clean, square cut and no burr in the end. I use a drill to deburr, good tubing cutters have a burr tool built in. I found a inexpensive flair tool that is build out of locking pliers, vise grip like, and works really well. It was less than 30 bucks. If you decide to use the type with the clamp bar and seperate flair attachment, clamp it in a vice, I've yet to use one that didn't slip, in fact, I refuse to waste my time with those kind. Mastercool makes a very nice hydraulic tube flair tool, but it's NOT cheap. Here's one similar to the inexpensive one.

I've read good things about this Ridgid 377.

 

Which flares are you wanting to do, 45 degree for inverted or 37 degree for AN fittings?

 

That's the flaring tool that I have for doing 37° flares. It works great, even on SS tubing.

 

I put just a smear of antiseize on the face of both the double and single flare face. I do not have to reapply for the second or following flares. Also doing a second tightening after loosening off seems to leave a good face. When installing the flared line, I tighten, loosen and retighten to seat the new flare to the fitting. I use the clamp type flaring tool made by Blue Point.

 

This is mine. Price has gone up since I got mine! Lol
link not working. Sorry

 

My nearly 50 yr. old new britian double flaring tool that I bought new has never failed me , only time I've had to cut off a flare is when I forgot the nut ! LOL
