We recently got BMW 760li M performance G12. It has the M blue brakes system, see image below.
When driving in extreme mode (it is for officials, almost always in rush mode) the brakes do not perform as well. They get so hot and smoke, then the brake pedal drops.
We were suggested to replace brakes with Brembo products. But a quick search showed they don't do brakes for this model. Contacted BMW, they said the current brakes are the best they have, and would not advise to put third party parts and if we do we lose the warranty.
Losing warranty is not a concern, so the question*:
How do I fix this issue, what can I do about the overheating, any advice?
*Also, posted at bimmerfest forum, no response yet.
Edit: Finally engineers established that the brakes were faulty, and replaced with new original brakes. The issue is fixed. I am closing this post, as it now seems off-topic. Thank you for all the comments.
