How to self-check the brake pads?

1. Listen to the sound. If light braking is accompanied by the sound of "iron rubbing iron", replace the brake pads immediately. Because the limit marks on both sides of the brake pad have directly rubbed against the brake disc, it proves that the brake pad has exceeded the limit. In this case, when replacing the brake pads, it is necessary to check the brake disc. When this sound occurs, the brake discs are usually damaged.

2. Look at the thickness. The total thickness of the new brake pads is generally about 1.5cm. When the braking degree of the brake pads reaches 0.3mm, replace them. With constant friction during use, the thickness will gradually become thinner.

3. Feel the intensity. When a car owner steps on the brakes while driving on the road, if it feels hard, there will always be a feeling of softness, and it is often necessary to step deeper to achieve the previous braking effect. It may be that the brake pads have basically lost their friction, and they must be replaced at this time, otherwise serious accidents will occur.

4. Look at the warning lights. Car owners can also use whether the brake warning light on the dashboard is on as a basis for judging whether the brake pads should be replaced. Note, however, that some cars only have brake warning lights. And generally speaking, the brake warning line is only available on the front brake pads. It is quite dangerous when the warning light is on. Because some of these alarm systems directly sense the thickness of the brake pads, and some will light up the alarm light when the brake pads are completely worn and the brake fluid drops.
