A better picture of my install. Click on the thumbnail to enlarge.


This shows how I used the cable casing as the travel stop so the lever arm cannot go over center. Also note how I used shrink tubing to keep the cable from slipping in the Adel clamp.
All screws that are difficult to reach are cap screws with plate nuts. They are much easier to remove for future maintenance than a pan head screw (Phillip's head) or a bolt and nut.

I have a T-Handle locking control cable that is mounted in the upper right hand corner of my panel. This where I tend to look when taking off and landing. The theory is that I won't do either with it pulled out and locked.

I was thinking about something similar to what Patrick did only farther forward since I'll have the fuel pump in that area. The layout looks pretty clean to me. I would be a little worried about having the lever down there getting bumped though. However, there may not be enough available height in that area for the lever, mount and etc.

If you do that, can you mount a lever on the fuel pump cover or on the fuel valve cover to activate and lock the brake valve? That would make it easier to activate.

Default Parking Brake Valve location

Bill,

Did you use the stock length primary braided break lines? Any problems with kinking or interfering with pedal action? About how far down from the top angle?

Thanks,
Alan

Default Like this?

Mine is mounted near the spar on my 7A. It can be easily reached with your right hand and no linkage is required.



More pictures and text involving my parking brake valve install at:

P.S. I was happy that I went to the trouble to install the parking brake. I haven't been flying a complete year yet, but I gotten myself into several situations where the brake was indispensable. (Like not being able to get out of the plane after parking without the plane rolling.)

Yes, they were the stock length braided lines and no, no issues with them kinking or interfering with the pedals.

When I first built the plane I used the plastic brake lines over to the passenger side. When I had it home for the engine replacement, I replaced all the interior lines with braided SS lines.

To fill the brake lines I bought a $10 chemical spray from my local big box store (Lowes) to push the fluid into the system. A pressurized "tool" is required to get all the air bubbles out. I cut the tip off the wand, inserted a 3/16" barb x 3/16" barb splicer (Lowe's part number A-95), and then inserted a 1/4" clear hose on the other end of the barb.* Loosen the nipple on the caliper, this is requires a 1/4" socket. Pressurize the container and squirt away. Do not get the small chemical sprayer because it is shorter, the air pump will be in the brake fluid and will put air bubbles in it when you pump it up.



To catch the brake fluid, I modified a small bottle from the auto parts store that is designed so you can bleed your car brakes by yourself. Pick up a 1/4" threaded section, a 1/4" x 1/8" tube to female pipe coupling with insert (Lowe's part number A-15), and some 1/8" clear vinyl hose.

Default mixture and prop

On my 7, I mounted the parking brake valve straight up above where the brake lines pass thru the firewall, I like to location, but be aware that is also in the same neighborhood that the mixture and prop controls go thru the firewall, at least for an IO engine. So depending on the firewall pass-thru method you will employ, the parking brake valve may or may not interfere with the placement of all.

I must agree that "that the further I deviate from the plans the time required goes up exponentially"
