What are the criteria for replacing brake pads?

[Melissa]

Here is the relevant introduction about the criteria for replacing brake pads: 1. Replace the front brake pads approximately every 30,000-50,000 kilometers, and the rear brake pads every 60,000-100,000 kilometers. 2. The specific replacement cycle should be based on the standard values required by the car manufacturer. 3. Whether the brake discs need to be replaced can be determined according to your driving habits. 4. The thickness of new brake pads is about 1.5 centimeters. When they wear down to one-third of their original thickness or less than 5 millimeters, they should be replaced promptly. Notes: 1. If you hear a metal grinding sound when braking, it may indicate that the brake pads have worn down to the minimum thickness, and the limit indicators on both sides of the brake pads are touching and grinding against the brake discs, producing abnormal noise. Immediate replacement is necessary. 2. If the brake pedal feels light, or you experience difficulty braking or insufficient braking power, it indicates severe wear and insufficient thickness of the brake pads, which also requires prompt replacement.
