Brake pads, also known as "brake shoes" or "brake pads", are small in size, but for the distance of the last few meters, the brake pads are also the most basic and important wearing parts of the active safety system. Because the brake pads are consumables, they will gradually wear out during use, and must be replaced when the wear reaches the limit position, otherwise it will reduce the effect of braking and even cause safety hazards. After replacing the new brake pads, these you need to pay attention to.
Why do I need to run in after the brake pad is replaced?
Brake pads are generally checked every 5,000 kilometers, and if the friction block is found to be less than 1 mm loss, it needs to be replaced. (Generally speaking, 30,000-40,000 km are replaced once). Moreover, the newly replaced brake pads also need to go through a certain running-in period in order to effectively exert its braking effect.
Brake pads and brake discs wear out after a period of use, and when the wear reaches its limit, it needs to be replaced. After replacing the new brake pads, the contact surface between the brake pads and the brake discs fails to achieve the best contact, affecting the braking performance, and the so-called "can't stop" situation will occur. Therefore, the replacement of the new brake pads needs to be run-in, so that the contact area between the brake pads and the brake discs is increased, and the braking effect is better.
How do the new brake pads fit in?
Usually, new brake pads need to be run-in for 200 km to achieve the best braking results, so it is recommended that vehicles that have just been replaced with new brake pads should be driven with caution. Under normal driving conditions, the brake pads should be checked once every 5000 kilometers.
The specific method of running in the new brake pad:
1. After completing the installation, find a place with good road conditions and few cars to start running in.
2. Accelerate the car to 100 km/h.
3. Lightly slam on the brakes with medium force to reduce the speed of the car to about 10-20 km / h.
4. Loosen the brakes and drive for a few kilometers to cool the brake pads and pads slightly.
5. Repeat steps 2-4 above at least 10 times.
Other considerations
1. In each 100 to 10-20km/h brakes, it is not strict to require a very accurate speed every time, and acceleration to about 100km/h can start this braking cycle.
2. When you brake to 10-20km/h, there is no need to keep an eye on the speedometer, just keep your eyes on the road surface, make sure to pay attention to road safety, about each braking cycle, brake to almost 10-20km/h on it.
3. In the course of these ten braking cycles, you cannot brake until the vehicle stops, unless you want the brake pad material to be integrated into the brake disc, which will cause brake vibration;
4. The running-in method of the new brake pads is to use the fractional point brake as much as possible to brake, and do not use the sharp brake before the run-in is good.
5. The brake pads after running-in still need to go through hundreds of kilometers of closing period with the brake discs to achieve the best performance, at this time, we must drive carefully to prevent accidents.
