Brake Line Flare Type
 

I'm replacing a rusted brake line on a 2001 GMC 2500 Savana van with a 5.0 liter engine. Can anyone confirm the type of flare that goes on the brake line? The double flare I made practicing looks too thick compared to the flare on the old brake line. So I'm assuming it's a single flare type.
Thanks

brake line do not use single flares...unacceptable
standard/imperial fasteners us a double flare
metric fasteners use a iso flare or "bubble" flare
google the terms and you will see what you have....each flare type requires a different forming tool.

Thanks. The issue was double flares were not compressed enough. More practice needed with new tool.
