Due to corrosion, the thickness and friction coefficient of the brake rotor change

  1. If the vehicle is parked in damp conditions for a long time, corrosion occurs on the friction surface of the brake rotor.
  2. The thickness of corrosion is uneven and sometimes appears like a wave pattern, which changes the friction coefficient and causes a reaction force.
