Customer statement / workshop findings: Noise complaint from the braking system. Workshop findings: The noise can be reproduced and clearly assigned to the braking system. Technical background Brake noises can be attributed to many causes. Eight of the most common causes are: - Brake discs or pads are close to their wear limit. - New brake pads and/or discs have not been properly bedded in after installation. - Aftermarket pads or discs are installed. - There is debris such as small stones, grit, road salt or sand between the brake disc and pad. - Discs are covered in rust. Rust can form when the vehicle has been stationary for long periods of time (Figure 1).","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201949-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201949-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10201949","components":[{"id":"brakes","name":"Brakes","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"BENTLEY","model":"ARNAGE","year_from":2004,"year_to":2009,"match":"exact","vehicle_ids":["2004_bentley_arnage","2005_bentley_arnage","2006_bentley_arnage","2007_bentley_arnage","2008_bentley_arnage","2009_bentley_arnage"]},{"make":"BENTLEY","model":"ARNAGE
