Re: Stainless steel brake lines

Bruce Hughes

Del, I have not looked over his
engine area.   I very much doubt
I would find a old style brass valve
like the first of the Longezes.    The
guy who built his Longeze did a VERY
GOOD construction job.   Every detail
that could be improved over the RAF
original plans seems to have been done.
Compared to mine, it looks much better.
But I have not looked at the brakes yet.

Today I will show him the information that
I have found in my archives.   Probably he
will call Dale Martin.   He might get an FAA
permit to take it to a repair site which should
make a flight legal to fly it  to Dale.   Or maybe
he will just fly it over. 

Or maybe he will just fix it with SS tubing.
I found Jim E.'s information about swagelok,
annealed SS being soft enough to coil for
shipping.   I have never worked with 1/8" SS.

Maybe he will call Marc Z.   I read his
comments on the subject.

I will call Ric Lee; I think he has SS on his Berkut.

I think SS lines are a very good idea and maybe mandatory.  My EZ had a brake fail because the nylon line got hot and soft and leaked.  I think that the conducted heat from the brake caliper, more than the radiated heat from the disc, soften the line and cause it to leak.  My Cozy had nylon, but it doesn’t any longer, after a Matco brake install.  The Cozy had a slight leak once but didn’t stop the brakes from stopping.   The new lines were < $100 and easy to install.


I would worry more about having the cheap plans brass fuel valve; that is mandatory to replace! They jammed up and almost caused a forced landing on both my airplanes, even though I painfully disassembled and lubed the valves periodically.

I have good brakes and never considered SS lines.


HOWEVER a buddy bought a beautiful Longeze.

Time came for a condition inspection last week.

The AI told him to deal with his less than perfect brakes

by replacing the plastic lines.   So he is grounded.


I told him that some builders had pushed SS lines

through their existing plastic lines and are very

happy with the lines.


He needs some expert help on that, please.
