Due to corrosion, the thickness and friction coefficient of disc plate change.
WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
- If a vehicle is parked in damp conditions for a long time, corrosion occurs on the friction surface of disc plate.
- The thickness of corrosion is uneven and sometimes appears like a wave pattern, which changes the friction coefficient and causes a reaction force.
