A special case of dynamic unbalance can be found in overhung rotors. It’s simple to check this yourself, but if you’re not sure, a specialist mechanic can give your vehicle the once-over for you. For the names of the data files, for example 'B007_0', the first letter represents fault position, next three numbers represent fault diameters (0.007, 0.014, 0.021 inches) and the last number represents bearing loads (0,1,2,3). For example, if a door bell does not ring when it should, it is only by means of a systematic approach that one determines that the bell itself is faulty. You might suspect overheating to be higher on this list, but in reality, it occurs rarely. There are three kinds of fault positions here, B-bearing rolling element, IR-inner raceway, OR-outer raceway. Owning a car is liberating, but maintaining it can be stressful, especially when things go wrong while out on the road and you’re faced with an expensive tow bill. Is the pressure in your tires correct, yet the steering is still listing to one side or another? Before fault is determined, the vehicle with the issue that caused the accident should be thoroughly examined. So this current is used to determine the rating of the CB.
