There are many kinds of noises in brake pads, such as high frequency squeal, low frequency howling, and dull reverberation. How did these problems come into being? What should we do when we encounter these situations?

The high frequency sound sounded sharp, and when the vibration frequency of the brake disc and brake pad of the North Mercedes parts in Baotou was the same, they resonate and produce screams. Check calipers: whether the guide rail is lubricated smoothly, the piston oil seal has no damage; all the noise proof clips and brake pieces are suitable, the installation is correct; the brake disc is too smooth and is overused.

Generally called caliper noise, it is caused by vibration of the caliper assembly, and may also be caused by the vibration of the suspension system. New car calipers or suspension system has a slight vibration, early morning sensitivity, such as winter morning, is particularly common. Check the caliper, suspension system and bushing.

General North Baotou Mercedes Benz parts are relaxed under the pedal condition, which can cause the steering wheel to shake. The new type is easy to cause this kind of problem, caused by the difference of the thickness of the brake disc, maintaining the cage connector and checking the wear degree of the brake pad.

The brake disc is abnormal after wearing. This is due to the dirty surface of the brake disc, uneven material density of the brake disc, too high working temperature, and incorrect installation torque of the brake disc. Inspection: the brake disc must be checked before replacing the brake pad of the Mercedes Benz parts in Baotou; the thickness of the brake disc is checked with the caliper; the fixed brake disc bolts are reinstalled; the working surface flatness of the brake disc is measured.
