Default Futaba 7PXR - help programming for parking brake

I need some help with my 7PXR. I have a custom 1/5 on road car that has both front and rear hydraulic brakes. Rear brakes are on channel 3 and front are on channel 4, so two servos are required, as I have two master cylinders. Channel 1 is steering and 2 is throttle. I have the brakes working with no issues, pushing forward on the trigger applies both front and rear brakes at the rate I have set it up for.

I would now like to assign a button that would apply both front and rear brakes so I can have a parking brake. So when the button is pushed, I want brakes on, about 70%. When not pushed, channel 3 and 4 control the brakes via the trigger.

I have tried conditions and mixing to no avail. I can select a button and assign it to channel 2 or 3, but it doesn't control the channel 2/3 servos. There is no brake 2/3 in the list of options to assign a button. In addition to having channel 2/3 on the list of options, there is also one named "brake", but it doesn't work, no movement of the channel 2/3 servos.

Anyone have any idea how to make this work?

In case you are curious as to why I need a parking brake..... I'm putting a jet turbine engine in it, so I need a parking brake for startup. Name:  1f642.png
