What Are the Causes of Low Metal Brake Pad Rattle?

Low metal brake pads rattling may be due to the brake pads become thin backplate grinding brake discs, low metal brake pads in the foreign body will lead to the case of rattling, so when the brake rattling first check the thickness of the low metal brake pads, the thickness of the problem without a few feet of brake may ease the problem of rattling. Here is an introduction to the causes of low metal brake pad rattling.

Here is the content list:

• After replacing the original low metal brake pads, the rattling caused by human factors

• Low metal brake pads rattling caused by injured discs

• Low metal brake pads rattling caused by friction block slagging or falling off

After replacing the original low metal brake pads, the rattling caused by human factors

This may be because the mechanic installed the low metal brake pads on the wrong side, and when you remove them, you can see that there are only partial friction marks on the surface of the low metal brake pads. At this time, you have to get the 4S store to remove and reinstall them.

Most of the sudden rattling after driving for some time is due to hard objects on the road such as gravel and iron scraps caught on the low metal brake pads when the brakes were applied, in which case you can go to a 4S store for cleaning.

Due to the manufacturer's problem, the size of the friction block of the same type of brake pad is not consistent, especially the width of the friction block, and the deviation of the size between some manufacturers can reach three millimeters. This causes the brake disc surface to look smooth, but the brake pads with large size will also ring if they are installed on the brake discs rubbed with small size low metal brake pads. If you encounter such a situation you need to first disc, such as not disc can drive for some time, and after the traces, the match will not sound.

Low metal brake pads rattling due to injured discs

The wounded disc here refers to the smooth surface of the brake disc, in addition to the low metal brake pads catching foreign objects during driving, there is also the manufacturer's uneven mixing process. Nowadays, due to the cost of brake discs, the hardness of brake discs is not as hard as before, which makes low metal brake pads especially easy to hurt the discs and produce strange noise.

Low metal brake pad rattling caused by friction block slagging or falling off

Long time braking can easily cause the low metal brake pads to fall off or fall off. This situation is mainly found in mountainous areas and highways. In mountainous areas, the slope is steep and long. Experienced drivers will use spot brakes to go downhill, but novices tend to brake continuously for a long time, which will easily cause the low metal brake pads to ablate and fall off, or when driving on the highway, drivers tend to drive faster than the safe speed. In case of emergency, the spot brake often loses its effect and continuous braking is necessary. This kind of long-time braking will often also cause the pads to ablate and slag off and cause the brake pads to rattle.

The brake caliper does not return for a long time, which will cause the brake pad temperature to be too high, resulting in ablation and deterioration of the friction material or failure of the adhesive, resulting in a strange noise.
