Rotor & worm shaft grinding. As the worm screws in a helical manner, but remains fixed in position, high axial forces occur. The corresponding sides are to be adequately supported, for example, with axial bearings depending on the operation being conducted (i.e. whether rotation occurs in one or both directions). The conditions for helical spur ...

A grinding noise when braking can indicate that your brake pads have worn down to the metal backing plate. When this happens the metal backing plate will grind into the surface of the brake rotor which it's not designed to do. As the metal on metal contact occurs this will damage the brake rotor beyond repair and will need to be replaced. 5.
