External force: Only one brake disc has grooves while others are normal, usually due to material issues or external forces causing this. 3. Possible factors: Foreign objects getting stuck between the brake disc and brake pad, coinciding with heavy braking; uneven force distribution of the brake caliper; manufacturing defects in the brake pads, resulting in uneven mixed materials, making the brake pads too hard or containing large metal particles.
