Today, I fabricated the parts to install the parking brake valve. The valve will be bolted to some hat channel I cut yesterday.



The lever might get stuck if aligned with the control cable, so I fabricate some part with two stops. On the picture, the lever in the open position in contact with the stop.



Here the closed position in contact with the stop.



The installation in the cabin needs for a bracket to be removed. The bracket was installed during the firewall assembly. I'll rivet the new support at the same place.



Here the part is installed; I still have to prime the parts. The forward ports will be connected to the left brake pedals and the lower ports to the brakes.
