Brake Line Flare: Double or Bubble?
 

The metric brake lines I've been able to find at parts stores are all bubble flared. I can tell that the diameter and thread count is right, but I'm not sure about the flare.

What do I need?

hmmm... a little info on what you're driving would help, but you're most likely looking at double flares. Easiest way to know for sure is take one off on your truck and look at it.

my 79 yota is double flare

Yet to see a Toyota that wasn't double flare on the brake lines.

:guitar:

Found the right type. It's a double flare.
