Brake Pad Wear Indicator

When you hear this noise, consult an Authorized Mazda Dealer as soon as possible.
| WARNING Do not drive with worn disc pads: Driving with worn disc pads is dangerous. The brakes could fail and cause a serious accident. As soon as you hear a screeching noise consult an Authorized Mazda Dealer. |
