WebLow Speed and High Speed Rotors Basic Theory and Definitions Balancing is the process of attempting to improve the mass distribution of a rotor, so that it rotates in its bearings without uncompensated Couple (Moment) Unbalance may be found in a rotor whose diameter is less than 7 to 10 times its width. Web26 mrt. 2024 · Some of it is related to the worn-out braking pad and also the usage of low-quality marked brake pads. There is another reason that lies behind the clips or shims not well installed or defective. So, vibration happens and it leads to high braking noise. Another reason is that the braking rotors have an uneven surface.
