| Check items | normal range | danger threshold | Check tool |
|---|---|---|---|
| Thickness | 10-12mm (new) | <3mm | Vernier caliper |
| Wear uniformity | Difference between inside and outside ≤1mm | ≥2mm | Visual inspection + measurement |
| surface cracks | No or ≤3 fine lines | Network cracks | magnifying glass |
| Metal back plate | No rust | rust through | Visual inspection |
| brake dust | A small amount of gray powder | A lot of metal shavings | white paper test |

4. Answers to the 5 questions that users are most concerned about
1.Q: How often should brake pads be replaced?
A: Usually 30,000-50,000 kilometers, but the actual mileage depends on driving habits and inspection results. Data shows that the vehicle replacement cycle on congested urban roads has been shortened by an average of 30%.
2.Q: How to determine when it’s time to replace the brake pads?
A: In addition to thickness detection, you should check immediately when the following conditions occur: ① The braking distance is significantly longer ② Sharp metal friction sound ③ The brake pedal is shaking.
3.Q: Can brake pads from different brands be mixed?
A: Mixing is strictly prohibited! Test data shows that mixing brake pads of different materials will cause braking efficiency to drop by more than 40%.
4.Q: Why is the price difference of brake pads so big?
A: The main differences are: ① Friction material formula (proportion of ceramic components) ② High temperature resistance level (normal type 200℃ vs competitive type 600℃) ③ Brand premium.
5.Q: Does it need to be run-in after replacement?
A: Required. The professionally recommended running-in method is: avoid sudden braking in the first 300 kilometers, and perform 20-30 progressive braking times to ensure that the friction material and the brake disc fully fit.
