What are the replacement criteria for front brake disc wear?

[VonCaroline]

There are several criteria for replacing front brake discs due to wear: 1. Wear: The maximum wear limit for brake discs is 2 millimeters. When the wear approaches this 2mm threshold, the brake discs must be replaced. During braking, the vehicle's stopping power is achieved through friction between the brake discs and brake pads. This continuous friction gradually reduces the thickness of both components. 2. Replacement cycle: In practical situations, most drivers find it difficult to determine when this wear limit is reached. The rate of brake disc wear largely depends on individual driving habits and also varies according to the vehicle's drivetrain configuration. Typically, brake discs on the primary drive wheels require replacement every 60,000-80,000 kilometers, while those on non-drive wheels can last up to approximately 100,000 kilometers.
