The Treatment Of Brake Pad
- Nov 01, 2017 -

One, sounded.

The main factors are caused by human factors and product factors.

Human Factors.

1. Remove the original car film after the new film.

At present, according to the actual situation, the original car brakes scratch the original car brake discs in the probability of more than 50%, but because of the original car parts, and secondly because the scratches did not sound, so 90% of the repair shop and The driver does not believe that the original car film injury plate, so the replacement of new films often do not take the initiative to check whether the brake disc scratches, until the new film when the re-check, only to find scratches on the brake disc, which often leads to the driver Requires a new film repair shop, dealer, manufacturer compensation brake disc. This is obviously caused by human factors. Treatment: Replace the brake pad must first check the brake disc with or without scratches, if scratches can be recommended to scratch or replace the new plate. If the driver does not agree, it should be marked on the repair sheet, signed by the driver, which will avoid the subsequent sound or injury caused by the driver claims.

2. Brake disc surface is flat but loaded with new film.

A: The first reason for this may be the repair workers to install the brake pad, remove the brake surface can only see the local friction traces. Solution: you can remove the re-installation.

B: The second reason: the current domestic manufacturers, the same type of brake pads friction block size is inconsistent, especially the width of the friction block, the size of the deviation between manufacturers up to three millimeters. This will cause the brake disc surface to look smooth, but the size of the brake pads if the size of the small brake pads to friction on the brake disc will also ring. Treatment: first CD-ROM, such as CD-ROM can not drive for some time, until the traces of anastomosis will not sound.

C: The third reason, after a period of time suddenly sounded, most of the time because of the brakes happened to have hardwood on the road such as gravel, iron scraps and other clips on the brake pad. This situation is not only sound, and easy to hurt the disk. But when the inspection is removed, sometimes the foreign body has fallen off or worn away. Treatment: CD, such as the film should be removed after the installation of foreign body. This is often the case of injury is just hurt the two sides of the four sides of the surface, is easy to see. But if the driver does not explain the reasons, it is easy to lead to claims.

D: driving after a period of time. But not squeaky, but crashed sound, which may be caused by loose accessories on the brake pad. Remedy: Re-tighten or replace the new film.

B: Product factor.

Here is the sound of the brake disc surface is completely smooth appearance of the case. The reason is that the current state prohibits the use of asbestos-containing brakes, but the domestic manufacturers generally do, and some small manufacturers are still in the production and sales of asbestos-containing brake pad. Semi-metallic non-asbestos brakes Although the mileage is long, conducive to environmental protection and personal health, but the material is too hard and asbestos brake pad because of the material is soft, often even if there is no scratches on the brake disc, and the brake feel soft Kind of situation can only replace the new film.

Second, the injury plate.

Here refers to the disc is the surface of the brake disc smooth smooth case, in addition to driving the brake pads caught foreign body, is due to uneven production process caused by uneven mixing. In fact, the current brake discs due to cost reasons, the hardness has been worse than before, even if the original car brake disc is generally not as good as before, which led to semi-metallic brake pads are particularly vulnerable to injury, as long as a slight scratch, 1 mm, there is no need to change the disk, as long as the plate can continue to use flat.

Third, the friction block dregs or fall off.


1. If the friction block color is not changed and dross is a product quality problems. Should replace the new film.

2. Friction block discoloration after dregs or fall off, the reasons can be divided into the following:

A, the caliper does not return, the brake caliper does not return to a long time, will cause the brake pad temperature is too high, resulting in friction material ablation, or adhesive failure, in this case, the friction material into red or yellow , This is not a product quality reasons, but to replace the new film and maintenance brake caliper.

B, prolonged brakes lead to dregs or fall off. This situation is more in the mountains more, the second is more in the highway. In the mountains due to steep road length. Experienced drivers use point brake downhill, but the novice is often a long time continuous brakes, it is easy to cause the film ablated dregs off the block, this dregs off the color will turn into red or yellow, then the highway Driving, because the road is good car, the driver often travel faster than the safe speed of 110 km / h, and sometimes even more than 200 km. In case of an emergency, the brake is often lost, must be continuous braking. This long time the brake will often cause the film to ablate the slag. The film color will change to red or yellow.

C, in the above A, B binomial dregs appear in the slag, does not belong to product liability, manufacturers do not assume responsibility.
