How often should the front brake pads be changed.
Generally speaking, a pair of brake pads with 100,000 kilometers is no problem, good use, and can even reach 150,000 kilometers;
1, because each driver brake frequency is not the same, it is difficult to define how long the brake pads need to be replaced. The only way is to look at the wear of the brake pads during routine inspections, and if it reaches a critical point, it must be replaced immediately;
2, generally the first replacement can be in 6-70,000 kilometers, some vehicles have warning lights will remind you that you need to replace the brake pads, or when the friction material on the brake pads ground to the steel back warning line, you will hear the noise, this time you need to immediately replace;
3, encounter some problems on the brake, this is a very bad driving habits, but in fact, it is also a hidden danger of accidents. In addition, there are people in the driving process, the foot has only two options: refueling, brake, brake frequency reached a very high level. In fact, such people are not rare;
4, and the result of doing so 20,000-30,000 kilometers, you have to change a brake pad. The correct way to drive is to keep focused at all times, look at the six roads, find problems in advance to slow down, according to the change of the situation to decide whether to step on the brake;
5, in this way, it can save gasoline and extend the life of the brake pads. In addition, when choosing to replace the brake pads, you need to choose good quality and try to choose the original parts, of course, the original parts are certainly no problem in quality, but the price is more expensive.
Front brake pads or rear brake pads which wear faster
Front brake pads
Front brake pads usually wear out faster than rear brake pads. This phenomenon is mainly caused by the following factors:
The relationship between braking force and axle weight: the size of braking force is proportional to the axle weight, because most cars are front-engine front-wheel drive design, the weight of the front axle is larger than that of the rear axle, so the braking force of the front wheel is also larger when braking, resulting in faster wear of the front brake pads.
Vehicle design: Modern automobile design tends to install the main components such as the engine and gearbox in the front half of the car, this arrangement makes the front mass distribution of the car uneven, the front wheel bears more weight, and requires greater braking force, so the front brake pads wear faster.
Mass transfer when braking: when braking, due to the inertia, the center of gravity of the car will shift forward, which is called the automotive brake mass transfer, further aggravating the wear and tear of the front brake pads.
Driving habits: stepping on the brake or usually stepping on the brake too heavy will accelerate the wear of the brake pads, affecting the performance of the car, endangering the safety of the passenger. Therefore, the correct driving habits, such as gently stepping on the brake and gradually applying force, can effectively extend the service life of the brake pads.
In summary, the front brake pads wear faster than the rear brake pads in most cases, which is mainly due to the design of the front weight after light, brake force distribution and driving habits and other factors.
The difference between front brake pads and rear brake pads.
The difference between front brake pads and rear brake pads mainly includes diameter, service cycle, price, replacement mileage, wear and replacement frequency.
Diameter: The diameter of the front brake pads is usually larger than that of the rear brake pads.
Life cycle: The life cycle of the rear brake pads is usually longer than that of the front brake pads.
Price: Although the front and rear brake pads are made of the same material, the price of the front brake pads is usually higher than that of the rear brake pads.
Replacement mileage: The replacement mileage of the front brake pads of the car is usually between 30,000 and 60,000 kilometers, and the replacement mileage of the rear brake pads is between 60,000 and 100,000 kilometers.
Wear and replacement frequency: Because the front brake pads endure relatively large wear, the number of replacement is more frequent, and the rear brake pads are more durable.
In addition, there are also some differences between the front brake pads and the rear brake pads in the braking effect. Because the front brake pads have a larger area in contact with the wheel, they need to bear more braking force to ensure that the vehicle can slow down quickly when braking. The braking force of the rear brake pads is relatively small. At the same time, because the front brake pads are located above the wheel, they are more vulnerable to the impact and vibration of the road surface, so they need to have better wear resistance and vibration resistance.
In general, there are obvious differences between the front brake pads and the rear brake pads in terms of design, service cycle, price, replacement mileage, wear and replacement frequency, etc., to adapt to different braking needs and vehicle characteristics.
