Nissan Altima noise when braking after new rotors and brakes installation on Nissan Altima

Some Nissan Altima owners report experiencing noise issues after installing new brake pads and rotors, which can stem from several potential causes. These owners note that during the breaking-in period, it is normal for some noise to occur, but it should decrease over time. Additionally, factors such as moisture, protective coatings, or improperly bedded pads can lead to squeaking sounds. Excess brake dust trapped between the caliper and rotor is another common issue that may cause noise. Furthermore, rust build-up from humidity can create uneven surfaces on the rotor, resulting in high-pitched sounds when contacting the brake pads; however, this rust typically wears off after a few minutes of driving. If noise persists beyond the breaking-in period, it is recommended for owners to monitor the situation and ensure proper bedding of the components.
