Unfortunately no, it spins loosely.

That was the LBS theory - he said he has seen them on other tricycles but with rim brakes. But it's puzzling because this is a feature of these tricycles. See 0:35 of
this video from the manufacturer.

We tried that, but by the point we got the pin to hold the brake, the brake was still partially engaged when the lever was released fully.
The velcro strap kluge idea is OK I guess but disappointing since this was supposed to be a feature, and it will lower the resale value to have a broken part.
