How do we know when brake pads will be replaced?

  • There is an alarm indicator when the alarm indicator makes an abnormal sound.

  • There is an alarm line displayed on the dashboard.

  • Without an alarm indicator and alarm line, need check frequently. It is a must to change when the friction material thickness is only 3 mm.

How do we know when the brake disc will be replaced?

  • The brake is judged by the thickness of the brake disc. In normally, the brake disc thickness of the vehicle is about 1.5 cm, when the brake disc thickness is worn to 1/3, or less than 5mm. It is recommended to replace the brake discs. The brake disc has a minimum thickness on the marking, less than it which needs to be replaced.

  • Through the prompt from vehicle, replaced brake disc. Some vehicles with higher configurations will be equipped with sensors for brake discs, when the brake disc has been worn to a certain extent, will note to replace brake disc.

  • If the brake discs reached the point when they need to be replaced, when the driver applies the brakes, will show a severe metallic rubbing sound from brake disc, also can judge from the sound if the brake disc need replaced.

  •  If it is unable to stop, or brakes are hard, need to check the use of brake disc, maybe it needs to replace it.

How to better run in the brake discs and brake pads when replacing the brake pads?

After replaced the new brake disc and brake pad, theirs surface can not reach the best optimal contact. Only full and correct grinding can reach the state of fitting into each other, to the best braking.

  • Suitable road segments. Before griding started, it needs one suitable road with less traffic. Because it can control the vehicle speed, and also ensure the safety of others and own.

  • Standard running-in process. Adjust the seat, and tie up the safe belt. The car is accelerated by a professional to 50 or 80 km / h with a slightly gentle brake pedal to press the force, move the car from 50 km / h until it stops, or slow down from 80 km/h to 30 km/h, accelerate when finished, and repeat the operation. There is no need to keep an eye on the speedometer at this time, you have to look at the road by car.

  • The run-in should be gradual. The interval between brakes can be more than 30 seconds to cool the brakes. Otherwise, continuous braking will cause the braking system to overheat, which is counterproductive.

  • Repeat the operation

    Follow the steps, more than 20 times, and the initial run-in is basically complete.

    When the above running-in operation is finished, it still requires a running-in period of about 300-500 kilometers (calculated according to general urban road conditions) to achieve the best braking performance. During the break-in period, heavy braking or continuous and slamming brakes during intense driving should be avoided as much as possible. Then, it will increase the running-in time, affect the braking effect and produce brake abnormal noise.



Analysis of the causes of brake shake vibration

  • The cause of brake pads or discs. If one of them is uneven or deformed, brake jitter will occur.

    Solution: replace the brake pads or discs to troubleshoot.

  • If the brake pads and discs are replaced, it was useful at this time, but it started shaking again, it is necessary to check the side hubs, deformation of the wheel hub can also cause sloshing when braking.

  • Four wheels are not aligned accurately or the tire balance is not good. It is very common. If the wheel alignment is not accurate or the tire balance is not good, it will cause a brake shake.

    Solution: Re-align the wheels or balance the tires.

  • The tie rod ball head falls off. At this point, the fault is serious, and the driver will feel “at a loss” and lose control of the vehicle.

    Solution: go to a professional repair site to troubleshoot.

  • The lower arm fixing bolt is loose.

    Solution: The driver can solve the problem by tightening the loose bolt himself

Each formula has its own advantages.e.g, the European market often uses low metallic as it is suitable for relatively flat roads;
Ceramic is with the best performance, and also it’s cost is the highest. Ceramic is not suitable for heavy vehicles , Such as SUV, semi metallic will be better, and it is apply to mountain roads.

Yes, it decided by the actual order.

If there are not many models, we can help you check out, but its accuracy cannot be guaranteed. In the end, you still need to provide an accurate reference number according to your market!

No noise,the quality is 100% guaranteed

Ceramic almost no dust, semi-metallic and low metallic formula brake pads will have a small amount dust, because these 2 formulas have metal materials, especially iron powder, caused the dust is too heavy to fly, will show the dust after fall on the hub.

A little, it is negligibled, almost 0.1-0.25kg.

Partial coated: 15-35µm Full coated: 5-20µm.
