Valve mounted on bracket with 90 degree line fittings going through the floor and flex lines going aft and down aft end of gear. I used bolts threaded into gear with clamps to hold the lines. Originally had metal lines down the fuselage channel but it looked like it cause more problems than it solved, so went with flex lines and no connections from parking brake valve down to the brakes. The channel will have a cover plate over it to protect the lines and clean it up. Parking brake handle under dash by center panel.
Valve mounted on floor all lines are flex
Lines to brakes go to outside and down middle channel to gear
1/4 turn ccw to unlock, and pull. Push in 1/4 cw and it's locked.
