I'm not sure I'd recommend CCB brakes over the standard brakes for no break squeal , the CCB will likely squeal more during cold, wet and moist conditions.
It's also interesting to see how many folks complain about this , same as oil consumption.
Not sure why this is but I have none of these issues whatsoever.
No oil consumption after 5800mls and no squeal at all (and that's also true for all my previous BMWs)
Maybe all the mountain pass driving/breaking did make a difference
