Flare-type brake line assembly and method of making the same

A method of sealing a flare-type brake line assembly including (a) a brake tube having a flare with a first sealing surface, (b) a brake component having a port with a second sealing surface and (c) a tube nut, comprising:

• treating at least one sealing surface of said first sealing surface and said second sealing surface to provide a first coefficient of friction between said brake tube and said brake component greater than a second coefficient of friction between said tube nut and said brake tube by (a) applying a material selected from a group of materials consisting of a paint, an adhesive, or a glue, to said at least one sealing surface or (b) roughening at least one sealing surface of said first sealing surface and said second sealing surface to increase said first coefficient of friction above said second coefficient of friction while maintaining sufficient sealing robustness between said brake tube and said brake component to prevent high pressure brake fluid from leaking between said first sealing surface and said second sealing surface when the first sealing surface is against the second sealing surface.
