When Should Brake Discs Be Replaced?

[DiEverly]

Brake discs do not have a definitive replacement interval, as their replacement timing is influenced by the vehicle's operating environment and the driver's habits. Generally, front brake discs should be replaced approximately every 60,000 to 80,000 kilometers, while rear brake discs require replacement around every 100,000 kilometers. Relevant details are as follows: 1. The replacement of brake discs is not determined by usage time or mileage alone; it primarily depends on the driver's habits and the quality of the brake discs themselves, ultimately reflected in the remaining thickness of the brake discs and their radial runout value. 2. Replacing brake discs does not necessarily require replacing the brake pads. If the brake pads still have substantial thickness, they can be retained when replacing the brake discs.
