Does anyone else feel bothered from the mismatch break calipers when you compare the nice front Brembo calipers to the rear Nissan looking calipers? I would like to upgrade to have them look more similar

Yes. I can't stand it.

Do they stop the car? I'm also usually inside the car when I'm driving it, so don't care what the calipers look like

This thread is Clown Shoes.

Also, it’s “brake”

....but you probably should do the fronts with a matching set to maintain brake balance:

BMW redesigned the parking brake which use to be a drum style brake housed in the rear rotor. That's why the rear on Gx chassis doesn't have fixed calipers like the front anymore, instead it's a single floating caliper which has the redesigned parking brake integrated into it. As a cost cutting measure, they just painted a floating caliper setup the same color as the front brakes, so they don't show the raw iron and become rusty after a few years instead of developing new fixed calipers to accommodate the new parking brake design.

Were they forced by regulation to change the parking brake?

Seems like a silly trade off.

Actually the eBrake with the drum, shows,, motor and cables are a nightmare.

Don't know, just that they switch to an electronic parking brake (EPS) which doesn't have the brake drum mechanism like the old parking brake. The EPS system electronically clamps the existing rear brake pads instead of relying on another brake in the rotor. For most this isn't an issue aside from aesthetics but for anyone that really drives their car to the limit it's problematic in that the single piston floating caliper does not apply pressure as evenly as static calipers, it's also smaller in size and made of cast iron which means it's more prone to heat soaking quicker than a larger caliper with muultiple pistons and made of aluminum. Lastly you can't just pull pins and replace the pads like you could on the F8x chassis, the entire rear caliper needs to come off. Real PIA if you track your car and need to swap pads. You also need to tell the car to retract the parking brake with ISTA or some other device to remove the caliper.

I guess that is another gripe for that other thread...yeah I wish the car had a manual parking brake.
