How Often Should Rear Brake Discs Be Replaced?

[Carolyn]

Generally, front brake discs need to be replaced every 60,000 to 80,000 kilometers, while rear brake discs require replacement at around 100,000 kilometers. Additional information: Brake disc replacement timing: Replacing brake discs does not necessarily require replacing the brake pads. If the brake pads still have significant thickness, you can replace the brake discs without changing the pads. However, this depends on the situation. Typically, brake discs need to be replaced once for every two sets of brake pads. When the combined groove depth on both sides of the brake disc exceeds 3 millimeters or the edges of the disc become sharp, it's time to replace them promptly. Factors affecting brake disc wear: The replacement interval for brake discs is heavily influenced by driving conditions and habits. Frequent braking in urban or mountainous areas accelerates wear, shortening the replacement cycle. Conversely, highway driving with less frequent braking naturally extends the service life.
