How to tell if the brake pads need to be replaced?
Brake pads are a very frequently used accessory in automobiles, so when they reach a certain period of use, they should be replaced in time. Let’s find out together, how to judge whether the brake pads should be replaced?
1. By checking the thickness of the brake pads. The braking principle of the car is carried out by the friction between the brake pad and the brake disc. If the thickness of the brake pad is less than 5 mm, it should be replaced in time.
2. By feeling. For those who drive for a long time, when driving a car, it is obvious that the braking system becomes sluggish and the braking force is reduced, and the brake pads need to be replaced in time.
3. The number of kilometers traveled. If the novice can't judge whether the brake pads should be replaced by feeling, it can also be replaced by the number of kilometers driven. Generally, the brake pads should be replaced when the car travels 30,000 to 40,000 kilometers.
4. According to the time. If the car has been used for two years, the brake pads should also be replaced in time.
5. The sound of stepping on the brakes. If you hear the friction between the metal when you step on the brakes, be sure to check the brake disc and brake pads. In addition to replacing the brake pads, if the brake disc is damaged, replace it together.
How often should car brake pads be replaced?
Car brake pads generally need to be replaced when the vehicle travels 20,000 to 30,000 kilometers, but if they are well maintained, they can be replaced after 40,000 to 50,000 kilometers. Step on the brakes. In this case, it is better to replace the brake pads in advance when the time is less than 20,000 to 30,000 kilometers. It can be replaced every few years. It can also be determined according to the specific conditions of use. If the driving frequency is high, generally It needs to be replaced once every 1 to 2 years, and the longest can not exceed 2 years without replacement.
Under what circumstances should the car brake pads be replaced as soon as possible?
1. The brake pads can be replaced according to the kilometers traveled by the vehicle and the driving time. For example, the brake pads should be replaced when the brake pads are driven for about two years or about 30,000 kilometers.
2. When the braking distance is much longer than normal and the brake becomes soft, if it is caused by insufficient brake oil, it should be added in time. If it is caused by the thin brake pad or brake disc, it should also be replaced in time. .
3. If there is a metal friction sound when braking, it may also be caused by the thinning or poor quality of the brake pads. If the thinning is particularly serious or the quality is poor, the brake pads should be replaced in time.
Advantages and disadvantages of ceramic brake pads
The difference between ceramic brake pads and ordinary brake pads is that ceramic brake pads do not contain metal, which is more durable than ordinary brake pads, has better heat dissipation, shorter braking distance, and can continuously brake at high temperature and high strength. For some vehicles, ceramic brake pads are suitable for mid-to-high-end models.
The general brake pad friction material will be affected by temperature. In actual use, whether it is low temperature or high temperature, it will affect the friction force, thereby affecting the braking effect. Ordinary brake pad friction material is immature, low temperature resistance, easy to rust, hard material, easy to break, easy to produce abnormal noise.
Advantages of ceramic brake pads:
1. Long service life, more than 100,000 kilometers;
2. Wear-resistant and high-temperature resistance, good thermal stability;
3. The heat dissipation of ceramic materials is fast and the friction coefficient is higher;
4. It has good mechanical strength and physical properties, and can withstand large pressure and shear force.
Ceramic brake pads have high performance, but of course there are disadvantages, high price, complicated process, ordinary cars will not be equipped with ceramic brake pads, only high-performance sports cars will be equipped, other than that, everything is fine.
