EV brakes are extremely complex because they need to feel like hydraulic brakes but be decoupled from the calipers unless the computer can't accomplish what the driver is asking for with regen, and then it must let the physical force of the drivers for continue through to the calipers. They have to fail safe when the computer is crashing and not calculating the motor field winding currents correctly for them to work.

In a Zoe, there is no coolant to change, it's an integrated heat pump system for humans and propulsion system.

There is very little maintenance a home gamer can do on it, alas.

EV braking system complexity has nothing to do with EV brake changes. It works exactly the same, you bleed brakes, and there's a brake fluid reservoir somewhere, you have brake pads. Nothing magic. It's all the same stuff.

Coolant... sure there's less coolant, but there still is coolant, it's just usually for cooling the battery and motors and not the engine. Most are lifetime fill, although most gas engines have >100k mile coolant change intervals already.

What maintenance are you suggesting even needs to be done? Tire changes/rotations, cabin air filter changes... there isn't much else you even need to do.
