Wrench Question

[Dan Barlow]

Squirrel has this covered. Basically it is a boxed end wrench with a section cut out of it for the brake line to slip thru. I have in fact made my own with a spare boxed end wrench of the size I needed .

It's probably a flare wrench. For a flared line.

If we saw what it was you were supposed to tighten with it, that would help.

One of the procedural steps in the Big Brake installation requires a 13mm flare wrench (got it) and a 17mm line wrench. It lists them that way on the required tools and names them that way in the procedural step.

What's the difference between a flare wrench and a line wrench and why can't I find a 17mm "line" wrench anywhere to save me?
