However, tweaking the earring bolt not only did not change the size of the gap, nor did it work at all. In installation, there are only two requirements on the earring bolt: one is to screw the back of the bolt back beyond the front face of the earring so as to prevent the backrest of the bolt from jamming the earring while the small brake is working; and the other two make the two braking earrings Bolts should be the same amount of protruding nuts, the purpose is to prevent brake pads and pressure plate partial wear.
