I have CCBS and donít have any squeal , I do wash my car a lot , I get very minimal from just the rears after a few hundred miles but very minimal ,
The discs really need to be power washed thoroughly to reduce the squeal , It actually tells you this in the on board instruction manual under CCBS cleaning
