My brakes have been squealing since I got my car coming up to 2 years ago. 19" Ti brembo setup. Even after new pads, there was squealing when moderate pressure is applied, not too low, not too much. The discs are still the same as when I got the car, with plenty of life left. The pads have been chamfered twice after this, no real improvement. When I go in reverse and brake, I hear a big clunk from one of the pads and a extremely loud squeal then starts. When I brake going forward again, you hear the clunk as the pad slips back into place then goes back to normal squeal with moderate pressure. I have also done a full strip down including thorough clean of the pads and caliper, applied new ceramic grease, still no real improvement. It has to be the parts, I have Mintex pads which are new, unknown disc brand though.
While these Brembos are certainly effective, they are so noisy and sound a bit primitive.
