Chapter 13/22 – Parking brake installed

Crazy that it took me about 7 hours to get all this done… of course, I had planned on getting much more accomplished than I did.

First, I watched a couple of videos on Flaring tubing and also did a review of the Matco emergency brake specs and installation, including a good video on that as well.

The flares on the right side brake tubing cross-connect, which I did after the left side, were much better than the left side’s.  Thus I cut a new length of tubing and remade the left side with much better flares.  I then did the final install of the left side aluminum tubing brake line cross-connect to the parking brake valve (pic 1).  I then did the final install on the right side brake line cross-connect as well (pic 2).

I then installed the Parking Brake engagement handle . . .

after I installed the parking brake ON indicator light microswitch (close up below).  After getting the handle cable installed at the correct engagement length in the parking brake valve lever, I did the final install of the Nose Gear RCU (Relay Control Unit) that was awaiting all the brake line cross-connect shenanigans to be complete to allow its installation.

Here’s an old closer-up shot of the microswitch that powers the panel “Parking Brake ON” LED indicator.

And another closer shot of the forward left NG-30/aft Napster bulkhead area.

And a video I shot 8 years ago showing the parking brake handle cable functioning:

Yep, slowing inching forward!
