Why do New Brake Pads Need to be Worn in?

Brake pads, also known as "brake shoes" or "brake skins", although small in size, is also the most basic and important vulnerable parts in the active safety system for the last few meters. Because the brake pad is consumable, it will gradually wear out in use. When it is worn to a limited position, it must be replaced, otherwise, it will reduce the braking effect and even cause potential safety hazards.

 

The brake pads are generally checked every 5000 kilometers. If the friction block is found to have a loss of less than 1mm, it needs to be replaced. (generally speaking, it is replaced every 30000-40000 kilometers). And the new brake pads also need to go through a certain running-in period to effectively maximize their braking effect.

 

 

Why do the brake pads need to be run in after replacement?

 

The brake pads and discs will be worn after being used for some time. When the wear reaches the limit, they need to be replaced. After replacing the new brake pad, the contact surface between the brake pad and the brake disc fails to reach the best contact, affecting the braking performance, and the so-called "unable to brake" situation will appear. Therefore, a new brake pad needs to be run in to increase the contact area between the brake pad and the brake disc and achieve a better braking effect.

 

How to break in the new brake pads?

 

Under normal circumstances, the new brake pads need to be run for 200 kilometers to achieve the best braking effect. Therefore, it is recommended that vehicles that have just replaced the new brake pads should drive carefully. Under normal driving conditions, the brake pads should be inspected every 5000 kilometers.

 

Specific methods for running in new brake pads:

 

1. After installation, find a place with good road conditions and a few cars to start running in.

 

2. Accelerate the car to 100 km / h.

 

3. Lightly press the brake and brake with medium strength to reduce the speed to about 10-20 km / h.

 

4. Loosen the brake and drive for a few kilometers to cool the temperature of the brake pads.

 

5. Repeat steps 2-4 above at least 10 times.

 

Matters needing attention:

 

1. In each 100-10-20km/h braking, it is not strictly required that a very accurate speed is required every time. This braking cycle can be started by accelerating to about 100km / h.

 

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 and ensure that you pay attention to road safety. About every braking cycle, you can brake to about 10-20km / h.

 

3. During these ten braking cycles, you cannot break until the vehicle stops, unless you want to integrate the brake pad material into the brake disc, resulting in brake vibration.

 

4. The running-in method of new brake pads is to try to use fractional point braking for braking, and not use emergency braking before running in.

 

5. After running in, the brake pad still needs to go through hundreds of kilometers of running period with the brake disc to achieve the best performance. At this time, you must drive carefully to prevent accidents.
