Brake pad inspection method

1. Look at the thickness: the thickness of a new brake pad is generally about 1.5cm, and the thickness will gradually become thinner with continuous friction in use. When the thickness of the brake pad is only about 1/3 of the original thickness (about 0.5cm) through visual observation. The car owner will increase the frequency of self-inspection and be ready to replace it at any time. Due to the wheel hub design, some models do not have the conditions for visual inspection, so they need to remove the tires to complete.
If it is the latter, when the warning light is on, the metal base of the brake pad and the brake disc are already in the iron grinding state. At this time, you will see the bright iron chipping near the rim edge of the tire. Therefore, we recommend to regularly check the wear condition of the brake pads to see if they can be used, rather than just trust the warning lights.
2. Listen to the sound: if there is "iron rubbing against iron" or noise (it may also be the effect of the brake pad running-in at the beginning of installation) when the brake is gently applied, the brake pad must be replaced immediately.
3. By foot feeling: if it is very hard to step on it, it is often necessary to step on the brake deeper to achieve the previous braking effect, or if the pedal position is obviously low when emergency braking is applied, it may be that the brake pad has basically lost friction and must be replaced at this time.
common problem
Q: How often do I change the brake pads? A: Generally speaking, the replacement cycle of the front brake pad is 30000 km, and the replacement cycle of the rear brake pad is 60000 km. Different models may have slight differences.
