How Long Does It Take to Break in New Brake Pads?
2 Answers
When replacing new brake pads, it is necessary to break them in for about 200 kilometers to achieve optimal braking performance. Here is some relevant information about brake pads: 1. Components: Brake pads are composed of a steel plate, adhesive insulation layer, and friction blocks. Since the new brake pads being replaced and the old ones in use have different degrees of wear, their thickness varies. 2. Brake Pad Wear Limit: If you hear a sharp metallic friction sound while braking during daily driving, you should pay attention. This phenomenon is likely the sound of the brake pad's wear indicator rubbing against the brake disc. In addition to replacing the brake pads, you should also check whether the brake disc is worn.
Just helped a friend replace brake pads the day before yesterday. The maintenance manual recommends a 300-kilometer break-in period. During this time, the brake pedal may feel softer, so it's important to deliberately maintain a longer safe distance. I advised him to take the national highway daily for his commute to avoid frequent stops and starts in the city. After each cold start, gently apply the brakes a few times at low speeds to activate the surface. On weekends, head to the expressway to perform five sets of gentle braking from 50km/h to 20km/h. Pay special attention to any abnormal noises during the later stages of the break-in period, as this is a key indicator of whether the pads are wearing evenly. Remember, don’t rush into long-distance trips with a new car—wait until the odometer hits the 300-kilometer mark before pushing it hard.
