Help has any one changer a metal brake line on a 95 blazer 4 door? I am just trying to find out if they are bubble flair or double flair

 

The brake lines are a double flare. If you don't have a double flare tool or are uncomfortable doing it, most auto parts stores sell pre-flared metal brake lines. Just match up the diameter & get a length close to what you need and bend it to shape to your original.

 

Brake lines have to be double flared by law and for safety. Its kinda tricky to get the hang of is you have never done them before, and you need a tool capable of doing the second flare too. A flaring tool wont work, you need one that does double flares.

I would just get close to the same legnth and bend it myself, flaring is a bugger and if you mess one up you might as well of bought the pre-flared lines. If the line is too long you can just make a coil in it like you see under your master cylinder, they do that so they are flexible. Just remember to bend them a little at a time, I like to roll them over a rounded edge cause if you bend by hand you can pinch it and then its trash.
