So here's a thread to post up ways you've used to do this.
There's also another thread I started a while back for security versions of steering locks, which while different is also applicable as it would also stop the wheel from flopping around:

One way to do a parkign brake is a locking brake lever, whcih generally has a springloaded push-pin in it that when you engage the lever you can then push the pin down to keep the lever engaged, then just squeeze the lever a bit more to release the pin.
This one was from a jogging stroller, back on my old DayGlo Avenger:

Below is a reply to a PM, but wanted to share the rest of what I was telling him about a steering lock, and then parking brakes, started in a different thread here;

I suppose it's possible this would weaken some headtubes/steerers enough to worry about, but so far no issues on the trike despite the loads/etc it sees.
Apparently I don't have any pics in the trike thread about it, but it's basically drilled straight in from the side of the headtube, into the steerer, right in the middle of the headtube vertically. In my case I wanted the wheel straight (so I could push the trike forward thru a narrow doorway from behind where I can't reach the handlebars, for instance), so I had the wheel straight when drilling the hole, but you could put it at any angle when drilling and then that's where it will lock it.
The actual pin used is like these, 1/4" diameter and about 2" long, IIRC. Mine came from some powerchair, I think, used to hold accessories on. Might've come from one of the jogging strollers I got years back to try to make a trailer from (they were held together by these pins so you could easily collapse them for storage).

I forget who suggested it to me, years ago; I think it was the local guy that fixes powerchairs that occasionally finds bits of them for me to re-purpose (it's where i get pretty much all my anderson SB connectors and heavy gauge wiring, circuit breakers, fuses, etc, and occasional hardware bits like these).1JohnFoster wrote:Dec 19, 2017 12:16 amGawd, I would never have thought of that! That will work for sure.
I have at least one of those pins in a bucket somewhere.
I meant ot implement it on DayGlo Avenger for exactly the reasons you need it, but never did it on anything until I built SB Cruiser, and even then not for a long time after.
Regarding locking brake levers, I used one off a jogging stroller for DayGlo Avenger for quite a while; but not all of them have the right leverage for the brakes you probably have on the bike. Problem Solvers has a pulley to fix that, though.
But you can also make your own, by drilling a hole in the lever housing so another of those cotterless pins will fit in there and jam the brake in the engaged position. Just depends on how your housing is built, so you aren't drilling into the areas that would weaken it.
Leave the pin hanging by the cable/ring when not using it, or keep it in a pocket, etc. Whatever works for you.
I've been planning to do this to SB Cruiser's front lever for a while, but didnt' yet because there's nowhere to do it on the Avid levers I'm using now.
So instead I thought about making a place to put the pin behind the brake *arm* instead, so I engage the lever and hold it, while sticking the pin in whatever plate/etc I put on the fork arch to do it with. Not as easy to use as a lever pin, though. :/ Easier to use a velcro strap to keep the brake lever squeezed (wrapped around the lever and the handlebar). Done that for years before I got the locking lever for DayGlo Avenger.
This won't work on all bikes (or trikes) very well, but it will work on some: You can take the clamp-on or bolt-on parking brakes off of wheelchairs, and put them on the stays or forks where they'll engage the tire. I did this for both rear wheels on the SB Cruiser trike:
