Nissan Sentra rough grinding noise when braking after startup despite brake pads and rotors replacement on Nissan Sentra

Some Nissan Sentra owners report experiencing a rough grinding noise when braking after startup, even following the replacement of brake pads and rotors. This persistent noise may be attributed to improperly seated brake pads, which can cause the grinding sound if not installed correctly. Additionally, foreign objects lodged in the braking system can lead to similar noises. Some owners have also reported issues stemming from the poor quality of replaced parts, such as low-quality brake pads or rotors that do not function properly. Furthermore, a lack of proper lubrication in the braking system can contribute to friction and grinding noises. Lastly, a worn-out wheel bearing may also be a culprit behind these sounds. It is crucial for owners to have a professional mechanic inspect their Nissan Sentra to accurately diagnose the cause of the grinding noise, as ignoring it could indicate serious safety issues.
