Performance Brakes
According to ZEVcentric, sometime in late 2022, the Model Y performance rear brakes stopped coming with Brembo calipers, and instead came with the same rear calipers and rotors as the non-performance Model Y but with nice red paint and a brake-caliper-cover that makes the caliper look bigger. src
DriveTeslaCanada reports that as of August 15, 2022, all Model Y Performance SUVS will have rear brake calipers manufactured by Mando and not Brembo. They went on to say that Tesla states there is no visiual difference and they do not impact the braking performance of the Model Y. src Mando already supplies rear brake calipers for the non-performance versions of the Model 3 and Model Y.
