I was doing a bleed, and had to plug up my overflow tube (vice grips) in order for the system to hold pressure. One thing I noticed is that I get fluid in the overflow at the track. This sends fluid down my inside wheel well on the paint. So I took some tubing and extended the overflow down lower so it does not touch the paint. Just thought I would post that for those of us who hit the track regularly. Hopefully this will keep your paint and corrosion protection in good condition if you (like me) have brake fluid in the overflow occasionally.

 

Did you also design a drain for when your longitudinal slave blows up, it can drain closer to the ground versus all over the underside? That would help, too!
