Brake noise has the common several kinds of high frequency low frequency scream, respectively, howl, dull echo. The question is how to produce? When we encounter these situations, how should we do?

High frequency sounds sharp, vibration frequency when the brake disc and brake pads is the same, they produce resonance scream. Check whether the smooth, caliper: rail lubrication piston oil seal is damaged; all the anti noise clip and the brake pads are suitable, installation is correct; the brake pads are too smooth, whether it is the excessive use of.

Commonly known as the noise caused by the caliper, caliper assembly motion, may also be due to caused by the vibration of suspension system. The new caliper or suspension system with a slight tremor, morning sensitivity, such as winter morning, especially. Check the calipers, suspension system and bushing.

Generally produced in the pedal relaxation, easy to cause the steering wheel vibration. The new type prone to this kind of problem, caused by the brake disc thickness difference, the maintenance cage connections, check the brake pad wear degree.

Brake disc wear after unusually, this is due to the surface dirty brake disc, brake disc material density, high working temperature, brake disc mounting torque does not match. Check: replace the brake pads must be checked before the brake disc; brake disc thickness caliper inspection; re install bolts fixed brake disc; brake disc surface flatness measurement.
