Six-speed touring 2016 Mazda6
Two technicians are perplexed by a mysterious braking noise. After having the brakes and rotors serviced, something occurred. Have had them recut with no success. There is zero wheel trembling or dragging. Several times, in order to examine the brakes, they were taken apart. The pins were adjusted by the mechanic, but nothing happened.
Reverse braking does not result in this.
The last moments of braking, when you come to a complete stop, are accompanied by a very pronounced and loud noise.
