How to judge the wear of brake pads
[Catalog:News] [Date:2022-10-14] [Hits:] [Return]
The wear degree of the brake pads is mainly judged by the thickness of the brake pads, the warning of the instrument panel, whether there is abnormal noise in the brake, and the braking effect. When the thickness of the brake pad becomes thinner, it is necessary to replace the brake pad. The normal brake pad is 1.5 cm thick. If it is found that the wear is only 0.5 cm, it indicates that the brake pad is not suitable for further use.
The brake lining is very important to the car. The brake lining will also be worn. The friction lining of a new brake lining is generally 10mm. When 5mm is left, it is time to replace the brake lining. The remaining 2mm is quite dangerous, and the brake pads must be replaced immediately.
Some brake pads will hide a metal needle in the friction pad. When the friction pad is worn to a certain extent, the metal needle will contact the brake disc, which will make a sharp abnormal noise when braking, reminding you to replace the brake pad.
If you find that the thickness of the brake pads is less than 1/3 of the original one, you should replace them immediately. Don't delay.
There is also an intuitive way to feel the change of brake force when you step on the brake. When you step on the brake, you always feel very hard, or the brake is not as sensitive as before, and you need to step on the desired braking effect with more force than before. When emergency braking occurs, you feel that the pedal position becomes lower and the brake pedal travel becomes longer, which means that your brake pads must be checked as soon as possible.
The simplest way is to look at the fault alarm light on the instrument panel. However, it should be noted that the flashing of this light is not the brake system as we call it, but the brake pad wear indicator alone. However, this light is not unique to ordinary cars. Only some high-end cars can have it. Some of these warning systems directly sense the thickness of the brake pads, while others will light up only when the brake pads have been completely worn out and the brake oil has dropped extremely.
