Look Ma, no Brakes!

It's what I could have said if I had proceeded with the finishing kit so, what happened?
After starting the wiring section with Anne, my favorite helper, I had to go back into the fuselage section to look-up some details. Oh! surprise! I discovered that I had missed a couple of pages that are dealing with the brakes plumbing. I had found bizarre to have 2 coils of plastic pipes left at the end of the fuselage works plus a few plumbing fixtures but did not worry because I thought that brake plumbing was done when the wheels are assembled in the finishing kit: wrong!
Once again, brake plumbing is a new learning curve to negotiate, different from gas plumbing because the fixtures are not the same. More later once I emerge from this new challenge.
Here are the pages I skipped:





Comments following completion of these brakes tasks:
The major difficulty is getting the fittings set-up as indicated in the first 3 steps of page 27-04. The problem stems from the fact that the plastic tubes have not a consistent inside diameter. For some the brass insert will go in easily for some it's impossible to push it in, even after dunking in boiling water if the sleeve is positioned as indicated. Here is my solution: I slide the sleeve further back and use the nut to push both the sleeve in position and the insert into the tube, whichever comes first. The rest of the job went well, I had only one question left about torquing the compression fittings after they installed are finger tight. Tony Tessitore reminded me that section 5 specifies page 5-12 to add one more turn after finger tight screwed: always read section 5 when dealing with new technology/process... and thanks Tony!
