Three days ago one of the black nylon brake tubes from the finger brake
master cylinder to the parking brake valve popped off when lining up for
take-off. I fixed it with a spare brass fitting with the white nylon
press ring inside, and taxi tested it before taking off. Today, the
exact same thing happened during run-up, so no flight.
- Any suggestion as to why this happended the first/the second time?
Must the tube be replaced if popping off (which I did not do but plan to
do now)? Did I tighten it too much/too little (not possible to tighten
more than I did the last time)? Perhaps I did not manage to push the
tube fully in over the brass tube in the fitting on the valve?
- While I am waiting for some more brass/nylon fittings from Europa, I
wonder if anyone has found a better nylon tubing/press fitting that go
onto the connectors we have? The black nylon tube looks so slippery that
it is almost a wonder that more of them have not popped off.
(yes, I know I should have replaced it all with aluminum tubing during
construction, but that is not my question!)
Best regards,
