What is the wear limit for brake discs?

[DelRosalie]

Brake disc wear is generally determined by a 5-year period or a wear limit of 1.6mm. Below are the relevant details: Brake Pads/Brake Discs: High-end vehicles usually have an alert system to indicate when brake pads need replacement. If this feature is not available, it is recommended to have the maintenance technician check them during each service. The general wear limit for brake pads is 2mm (same for front and rear brake pads). It is advisable to replace them when they wear down to approximately 2mm remaining, as failing to do so may result in longer braking distances and, in severe cases, inability to stop the vehicle. Engine Peripheral Belts: Most vehicles are equipped with peripheral belts. Regardless of the number of belts, they should be replaced every 60,000 kilometers or 4 years. When replacing the belts, the belt guide wheels and tensioners should also be replaced simultaneously. Otherwise, belt breakage or guide wheel jamming during driving may cause the wheels to malfunction.
