How do I tell what I need to replace the brake lines on my car?
It's really very complicated. If you don't normally work on your own car, now is not the time to start. Please seek professional help. If you always do your own work but have never really done brake lines, it's worthwhile to figure it out. Once it's figured out, the install is fairly straight forward.

We do not make or sell flex line/brake hose assemblies.

Is there a corrosion problem due to dissimilar metals when using Cunifer™?
No more than usual. Always anti-seize nuts and tubing.

Brake line flaring tools vary widely in quality. If you can flare steel tubing with your flaring tool, you can flare Cunifer tubing.

Why do we say not to use flaring tools with serrated grips?
Serrated grips damage the end of the brake tubing no matter what kind of brake tubing you use.

What punch and die sets do I need?
For Double flaring for common American brake line applications order 007B with 3/16" and 1/4" punch and die sets.

For European applications order 007B with 3/16" and 4.75MM punch and die sets.

The best choice - order 007C with 3/16", 1/4" and 4.75MM punch and die sets. This set allows you to do virtually all brake line applications (except Citroen!).

The 4.75MM/bubble flare is beginning to appear on late model American cars and trucks.
