Re "stainless steel braided line", Ed:  The stuff inside the "stainless steel braid" ain't "steel" - it's rubber and/or teflon tubing - stuff that will melt from heat soaking from hot calipers back into hose.

Well, I hope you're wrong about the melting part David.  The Earl's hose I'm using is good for 300F. 
 
I've seen planes with plastic line throughout.  In fact, the Kolb in the garage has plastic now, but it won't when I get done with it.  I've got no problem with using plastic for the reservoir, just not the pressure lines.
 
On the RV-8, I used the aluminum tubing that Van's sent, and never had a bit of trouble with it.  On the RV-3, I used aluminum, and had 2 or 3 different occurrences of cracks near the fitting on the brake caliper.  The gear on the -3 has some shimmy problems, so I figured it was just getting shaken too much.  With that in mind, I thought perhaps I had too much loop, but reducing it didn't help either.  Stainless braided hose did though :-)
 
Cheers,
Rusty (no dyno purchase today)
