Mazda CX-9 brake squeaking and grinding due to worn pads and rotors replacement needed on Mazda CX-9

Some Mazda CX-9 owners report experiencing brake squeaking and grinding noises, often attributed to worn brake pads and rotors that may need replacement. These issues can arise from new brakes and rotors not being properly bedded in, rust and debris forming on the brake disc, or moisture on the brake pad or rotor surface after installation. Additionally, grinding noises may indicate worn friction material on the brake pads, worn noise reduction shims, or heat-degraded anti-rattle clips. Owners may also encounter problems with grooved rotors or binding brake pads due to a seized caliper. It is advisable for owners experiencing these symptoms to have a professional inspect the brakes to assess wear and determine if replacement is necessary, as regular maintenance can help ensure safer and quieter driving experiences.
