This may be caused by the rear brake pads not having the capability to remove the rust from the rear brake discs. The red rust accumulated on the discs is exposed to high temperatures during braking, and consequently the rust turns black. As the black rust is too hard to be removed by the brake pads, the rust progress is accelerated, resulting in the grinding noise.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10198568-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10198568-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10198568","components":[{"id":"brakes","name":"Brakes","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-3","year_from":2019,"year_to":2020,"match":"exact","vehicle_ids":["2019_mazda_cx-3","2020_mazda_cx-3"]},{"make":"MAZDA","model":"CX-5","year_from":2016,"year_to":2020,"match":"exact","vehicle_ids":["2016_mazda_cx-5","2017_mazda_cx-5","2018_mazda_cx-5","2019_mazda_cx-5","2020_mazda_cx-5"]},{"make":"MAZDA","model":"CX-9","year_from":2016,"year_to":2020,"match":"exact","vehicle_ids":["2016_mazda_cx-9","2017_mazda_cx-9","2018_mazda_cx-9","2019_mazda_cx-9","2020_mazda_cx-9"]},{"make":"MAZDA","model":"MAZDA6","year_from":2016,"year_to":2020,"match":"exact","vehicle_ids":["2016_mazda_mazda6","2017_mazda_mazda6","2018_mazda_mazda6","2019_mazda_mazda6","2020_mazda_mazda6"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
