What does the brake disc guard do? Brake disc protector friction abnormal noise?
The main function of the brake disc protection plate is to prevent the splash of small stones and other debris from damaging the brake disc, and it also has the function of heat insulation and protection of the brake system. Specifically, the brake disc guard (also known as the fender or baffle) is not a simple decoration in the vehicle design, but works closely with the air guide system to guide the air flow to provide heat dissipation for the brake system. In addition, it can also effectively block foreign bodies and avoid damage caused by splashing stones or debris hitting the brake disc, especially at higher speeds, this protective effect is particularly important. Although the brake disc guard itself may be only a thin sheet iron, its role can not be underestimated, to provide better protection for the brake system, to avoid abnormal wear or damage caused by foreign bodies.
When considering whether to remove the brake disc protection plate, it is necessary to consider its actual role and possible impact. Although it may bring a certain heat insulation effect, the main purpose is to prevent foreign bodies such as sand and stone from entering and protect the brake disc from damage. Therefore, when deciding whether to retain or remove this part, the protection it provides should be fully considered.
Brake disc protection plate friction abnormal sound may be caused by several reasons:
The spacing between the brake pad and the brake disc and the tightness of the nut are not adjusted properly and need to be reinstalled. If the brake is worn in one direction for a long time, it will cause some burrs on the reverse surface, and when the reverse gear is pressed on the brake, the burrs and the brake disc friction produce abnormal sounds, and the brake pads need to be polished.
Brake disc material is hard, will also cause abnormal sound, do not affect the use of it, do not need to be processed.
Brake caliper problems, such as movable pin wear, spring flake off, etc., will cause abnormal sound, need to go to the repair shop to find the fault and repair.
In the case of emergency braking, the vehicle will also emit abnormal sound, which is a normal phenomenon.
Between the brake disc and the brake pads may be mixed with small stone debris and other foreign objects, which will produce abnormal friction when the brake is pressed, causing the brake disc to squeak.
Severe wear of brake discs and brake pads can also cause abnormal sound of brake discs. If a deep groove is found between the brake disc and the brake pads, they need to be repaired or replaced in a timely manner.
Brake pads or brake discs may break or drop due to quality problems, which is also a common cause of abnormal brake sound.
Solutions to the above problems include:
If it is caused by a foreign object, you can try to step on the brake several times or clean up the foreign object.
Check brake pads and brake discs for wear and replace them if necessary.
If it is because of brake caliper problems, such as movable pin wear or spring flake, you need to go to the repair shop for repair.
For the abnormal sound caused by emergency braking, it is a normal phenomenon and generally does not need to be dealt with.
The above information is for reference only, and the specific situation needs to be determined according to the actual check.
Can the brake disc guard be removed
Brake disc guard plate can not be removed.
Brake disc protection plate, also known as mudguard or dust cover, its main function is to prevent dirt and impurities from splashing on the brake disc, to avoid these foreign objects have an adverse effect on brake performance. If the brake disc protector is removed, the following problems may occur:
Affect brake performance: soil and impurities attached to the brake disc will cause abnormal wear between the brake disc and the brake pad when braking, resulting in poor braking effect.
Accelerated wear: Without the protection of the protection plate, the brake disc and brake pads will be more vulnerable to wear and shorten their service life.
Cause surface roughness: The presence of impurities may lead to the surface roughness of the brake disc, which in turn affects the smoothness and safety of the brake.
Therefore, in order to maintain good braking performance and extend the service life of the brake system, it is not recommended to remove the brake disc guard plate by itself.
