The thickness of a new brake pad friction material is about 1.5cm (0.6inch). With the continuous friction in use, the thickness will gradually become thinner. When the thickness of the friction material is only 1 / 3 of the original thickness, about 0.5cm, it is necessary to increase the self inspection frequency. It is recommended not to be less than 3mm, otherwise the braking effect will be lost and not sound.
Secondly, it can also be judged by the sound. The limit marks on both sides of the brake pad have directly rubbed the brake disc, which proves that the brake pad has exceeded the limit. There is noise after gently stepping on the brake, which indicates that the brake pad needs to be replaced immediately.
The purpose of replacing the brake pads is to ensure the safe driving of the vehicle and provide stable and controllable braking effect. We recommend that the brake pads be replaced once every 45000 km or 24 months under ordinary road conditions.
