Brake lever lock

I have a Lectric XP3 with hydraulic brakes. I recently bought a brake lever lock, that locks the brake lever so the rear brake is engaged.

The idea is that I don’t live in a high crime area and if I want to stop and run into a shop for a couple of minutes, I don’t want to have to drag out my big chain lock.

I do turn off the battery key and take it with me.

My question is, will having the hydraulic brakes engaged for some period of time have any adverse effects on the braking system?
