REFLECTOR: Brake Lines

[Al Gietzen]

Kurt;

 

You could consider tossing/returning the Nylaflow, and taking another
approach. I used 3/16" 6061 aluminum from the masters through the wiring
duct to the gear bulkhead on the retract version - then to 3/16" Teflon
braided SS for a flex bend (needed for the retract) and glassed to the leg
down to the caliper.  Where it is glassed to the leg I put heat shrink
around the tubing to allow some give for the flexing of the leg.

 

I made a radiation heat baffle from thin SS to shield the leg from the brake
rotor.  This can be seen in the attached photo of the caliper.  It mounts
between the axle flange and leg and extends up between the leg and rotor.
I've made hard stops to the point of brake fade and have no issues with leg
deformation.

 

Best,

 

Al

Need some input:  The original brake "Nylaflow" that came with my kit isn't
quite long enough for the 173 FGE.  So, I bought some new stuff. They are
the same OD, but not the same ID. The NEW stiff is thinner wall and is too
big for the compression inserts that came with the kit. 

 

The Original part:  S&L Plastics Nylaflow Pressure Tubing Type 3/16"H SK8201

 

The New Stuff:  S&L Nylaflow Pressure Tubing Type 3/16"T SK8201

 

I am guessing the "H" is Heavy Wall, and the "T" is thin wall. 

 

The inserts from the factory fit the heavy wall tubing  (that is too short
for the airplane). 

 

The thin wall stuff is what the Wicks and Spruce Catalogs say is used for
brake lines. Spruce doesn't have an insert listed that I could find, Wicks
has one that says "3/16" part number 2030x4" 

 

What kind of Nylaflow is being used? If it is the thin wall stuff, what is
the part number for the insert?

 

I either need to order new (correct) nylaflow, or new (correct) fittings.
any input? 

 

Another screeching stop due to incorrect parts. 

 

Thanks   Kurt
