This doesn't effect me but man...I feel so torn about this.
On one hand @thesmokingman is absolutely correct, the rear Brembo calipers are also just floaters with a red cover molded into the brake to look as if they're proper opposing piston fixed calipers...if you don't look too closely. They are just as fake as these Mando rear calipers.
On the flip side, from the look of it I would guess the Mando calipers are less stiff than the Brembo calipers. And having the fake-fixed-piston cover molded in means no risk of it coming loose and making your car seem like a cheap PoS with appearance parts falling off like the OP experienced. Plus, you paid for a car with "performance" brakes. I would argue the Brembo brand fulfills that feature better than Mando.
So I agree with @thesmokingman and I also agree with @jjrandorin. It's really no big deal from a performance perspective, but it's still misleading and I would feel ripped off if I bought the car expecting performance brakes, and all I got was a caliper cover stuck on identical brakes as the regular Model Y.
