Seeing as how I barely made it out of high school, can someone please explain this to me.

If the outlet ports on the MC is 3/16, and all the ports on the residual valves and propr valves, are 3/16, how the hell do you run 1/4 line? And what good would it really do if the intial point of exit at the MC is 3/16.

I'm not rying to disagree with Ogre, I am just trying to wrap my head around hydraulics.

I decided to clear off my bench and get all my new brake stuff out. I thought it would be good to practice so I grabbed my old lines and started cutting and flaring.

I used a drill bit and a file to clean up the lines before flaring. Good thing I'm practicing lol couple arnt pretty.

Question:

I'm comparing my flares to the donor's lines and im wonder if both kind work in the proportioning valve. Keep in mind that the old stuff I'm practicing on and comparing to are from 1984. My new valve looks just like my old one, do both flares work? Here's a pic of the old lines flared end and next to it is one I made. Old on right newly flared on left.

Or are these the same and I'm doing something wrong?

Watched Eastwood video and had a real duh! Moment. I had the dies turned around. Also learned not to be scared to really tighten down on the dies too because the lines would move and that didn't help my flares either. I was also not getting the inside burr completely, thought I was but instead of a drill bit I used tang of file and I got a lot more out. The video used a triangle thing but the tang works pretty good.

I practiced on old lines and finally decided to cut a small piece off the new stuff. It helps that it seemed softer. Flared both ends of a 3 inch piece. Beautiful!! I can't wait to start running the lines.

The original lines used the old engine crossmember. Where should the new one go if I have a swapped in v8 tubular one now?
