Some of the places I've flown to have inclined parking and often there is a lot of wind when I land at airports away from home. In my Mooney I would simply put on the parking brake until I could hop out and apply chocks to the wheels. Van's does not include a parking brake as part of the standard design for the RV14. I've spent the last couple of weeks noodling out how to install a parking brake and came up with this design:
I added a push/pull cable to the left of the cabin heat on the pilot's side of the control panel.
And I installed a Matco PVPV-D brake valve on the side skin of the fuselage. When you activate this valve, it retains the pressure between the valve and the brakes. If you apply braking using your toes and then throw the valve, it will lock the brakes until the valve is released.
Here are the parts I purchased:
I quickly discovered that the straight hose fittings would not work. The nylon brake tubing will not bend sufficiently to allow attaching straight into the valve. So I ordered 90 degree elbows. I also sourced a cable connector from Aircraft Spruce that would fit on the arm of the brake valve. Here are the parts:
Originally I was going to attach the valve to the longeron that supports the rudder pedal cross tubing, but I ran into trouble routing both the push/pull cable and the brake line connections. A friend who built a 14A attached the valve on the center sub panel support, but for the tail dragger version that is not convenient because the brake lines run to the firewall. I eventually determined the best mounting spot is on the fuselage side skin in line with the control panel bottom so the control cable has a straight shot to the brake arm and also the brake lines can be routed to be out of the way of feet on the rudder pedals.
I drilled 4 holes through the side skin and dimpled them for the mounting screws.
If I had known these holes were needed before assembling the fuselage it would have been a simple matter to dimple them. To dimple them after the fuselage was completed required a different approach. I drilled a hole in a bucking bar so I could insert a dimple die and I took the die holder out of my c-frame and mounted it in my rivet gun.
