Update March 2021... After using the disc brake setup for a parking brake I went back to a v-brake . Due to the flex of the rear wheel in turns the disc brake pads would slightly rub on the rotor while turning. I don't light rubbing noises, especially so close to my head, annoys the heck out of me. If I were to adjust the disc pads so they wouldn't rub then it would become useless as brake for parking.

I changed out the rear rim parking brake for a disc brake.
What I've learned:
1. With a rim brake removing the rear tire from the trike requires an extra step...reaching underneath the trike and releasing the brake cable so the tire can slip past the brake shoes. Doing it with one had requires a bit of dexterity. Doing it with both hands requires getting down on your ass to reach under the trike or putting the trike on its side. With a disc brake no extra step required.
2. The rim brake doesn't have the same holding power to prevent the trike from moving while trying too dismount on a hill. The disc brake has better holding power.
Recumbent Trike Store has a rear disc brake kit so you don't have to accumulate the components.
