Began by drilling and bolting the middel rudder brace mount support. then Installed the brake lines . both the braided stainless steel and the nylon. i had to make a trip to AEROZONA parts to pick up a couple of AN fittings, the ones suplied in the kit are 90 degree , but with the MATCO parking brake valve, i needed straight couplings. There is some rubbing of the braided lines, I'll try some adjusting, but i expect i'll need to get some spiral shiled and put around one or both. it wouldn't be a bad idea even from an appearance point of view. Installing the nylon lines took a bit more work than I expected. I installed them on the Left side of the cockpit first and no problem. The problem is getting the small bradd make fitting installed on the other end AND THEN getting the compression fitting to move down far enough so that you can get the threads started on the brass coupling, with one oend already attached theres' not a lot of leverage to get the fitting inserted and then compressed, so it took a but longer than expected. Everything else went fine.
