I posted on April 8th about a double flaring tool that I was going to use to improve my
brake lines to the front wheels. They have been a single flare since 1979 when the car
was first completed. It had this CF plumbing that we cobbled together in 79, at the time
and it worked, so it never got replaced until now.
Lisle 33260 Double Flare Tool
The inverted brake line Tee and the inverted flare to AN4 adapter were not compatible,
the adapter only caught about 2 threads and when I tightened it stripped. I looked at
several online sites, but they all had the same two Tees. Maybe the other Tee would
work, but I was not willing to try it out. I backed up and bought all the fittings I needed
to go straight AN fittings except at the MC. I already had the Rigid (PN 377) 37°
flaring tool.
Next was to 3D print my own bracket for the two bulkhead (see PN at bottom) fittings.
So I fired up my 3D program called FreeCAD, a parametric 3D modeler to design
the brackets. It took several prints to get the hole sizes perfect to give me a snug
fit on the Tee. The 3D printer is accurate to about .006"
Next I needed a brake line support, so back to FreeCAD and several more test prints to
get exactly what I wanted. Below you can see the printer at work. My front cross member
is 3.5 inches in diameter, so I made the support to fit the curve. I made the hole for the
brake line about 190° so it would just snap-in place.
Most plastics can be smoothed more than what you see above with Acetone or you
can use some body filler and paint to get exactly what you want for a surface finish.
