Your rotor disc is worn out because you might have exposed it to cold water while still hot. Such an act can lead to a surface deflection of the rotor, leading to grinding sounds when braking. Other reasons include: Solid item stuck up in between pad and rotor. Parking the car for too long; Unlubricated caliper screws; Broken shims

Taking the plunge grinding of the crankshaft main journal as the research object, this study equates the grinding process as a dual-rotor coupling vibration, and a double-rotor dynamic model of crankshaft grinding system was established. An iterative algorithm of "grinding force instantaneous grinding depth" is proposed to simulate the ...

The grinding stops when breaks are pressed. Braking perfromance appears to be perfectly fine. So thinking maybe it could be the plate on the back of the rotor rubbing against something I inspected it and made it wasn't making contact. I started to spin the rotor freely to listen for grinding noise and it was still there.

Grinding pressure on both sides of the rotor is kept approximately balanced, reducing the effects of any very slight possible runout in the dead center mounting. The grinding wheels are advanced into engagement with the rotor surfaces as successive finishing passes are taken with the rotor and this may be controlled as described in my earlier ...

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.
