D1051 Brake Pads

Main material: carbon fiber ceramic formula

Process: equal ratio isobaric, one-shot molding, high-temperature infrared ablation

Strength: ≥2.5MPa

Coefficient of friction: 0.36

Effect: good noise performance, basically no ash, comfortable brake

The brake pad, which we usually call the friction brake pad, is an important component of the brake system. It acts on the brake disc (or drum) when it passes the brake of the vehicle to achieve immediate deceleration or parking.

Seven reasons for the abnormal sound of the brake pads

First, the brake pad material and other product factors caused by the sound

If the brake pad material is hard and poor, such as the use of asbestos-containing brake pads, but some small manufacturers are still producing and selling asbestos brake pads. Semi-metal asbestos-free brake pads have a long driving range, which is good for environmental protection and personal health. However, the material is hard and the asbestos brake pads are soft, so even if there are scratches on the brake disc, the brakes will not sound, and the brake feels soft. It is the sound of this situation that you can only replace the new film.

Second, after replacing the original brake pads, the sound caused by human factors

1. It may be that the repairman has biased the brake pads. When removed, you can see that the surface of the brake pads is only partially scratched. At this point you will get the 4S shop removed and reinstalled.

2. Due to the manufacturer's problem, the size of the friction block of a type of brake pad is inconsistent, especially the width of the friction block, and the dimensional deviation between some manufacturers can reach three millimeters. This results in a smooth surface of the brake disc, but a large-sized brake pad can also ring if it is attached to a brake disc that has a small brake pad. In the case of such a situation, you need to first disc. If you don't have a CD, you can drive for a while. If the traces match, you won't be audible.

3. After a period of driving, it suddenly sounds. Most of the hard objects such as sandstone and iron scraps on the road are caught on the brake pads. You can go to the 4S shop for cleaning.

Third, the friction block caused by the friction block slag or falling off

1. Long-term braking can easily lead to slag or falling off. This situation is mainly seen in mountainous areas and highways. In the mountains due to the steep slope. Experienced drivers will use the brakes to descend the slope, but the novices often brake for a long time, which will easily cause the film to ablate and slag, or the driver tends to travel faster than the safe speed when driving on the highway. In the event of an emergency, the brakes often lose their effect and must be braked continuously. This kind of long-term braking often causes the film to ablate and slag and block the block, resulting in abnormal sound of the brake pads.

2. If the brake caliper does not return for a long time, the temperature of the brake pad will be too high, causing the friction material to ablate and deteriorate, or the adhesive will fail and cause abnormal noise.

Fourth, the brake master cylinder returns slowly

The brake master cylinder returns slowly, and the brake cylinder return to the abnormal position will also cause the brake pedal to be abnormal.

Five, the brake pump rust

If the brake oil is not replaced for a long time, the oil quality will deteriorate, and the moisture in the oil will react with the sub-pump (cast iron) to rust.

Sixth, the brake disc caused by the broken disc

The wound disc mentioned here refers to the wound disc under the condition that the surface of the brake disc is smooth and flat. In addition to the foreign matter caught in the brake pad during driving, there is also the uneven stirring in the production process of the manufacturer. Nowadays, due to the cost of the brake disc, the hardness is not as good as before, which causes the semi-metal brake pads to be particularly prone to damage and abnormal noise.

Seven, the hand kill cable does not live

If one of the two hand-crushing wires does not work, it will cause the brake pads to be different. At this time, you can adjust or replace the hand-pull cable.

There are so many reasons for the abnormal sound of the brake pads, so how to deal with the abnormal situation of the brake pads, first of all we have to analyze which kind of abnormal sound is in the targeted treatment.
