RX4 - Squeaking, now Grinding noise from front wheels

After hearing the one of the wheels making a squeak sound every now and during certain turns, the squeak noise has just now turned into a a semi-permanent grinding noise.



I presume that it's the pads that are no longer there, and it is metal on metal...



Anyone pointers on this to help confirm this finding or if it might be something else, will be greatly appreciated.



Other than that the RX4 has been a very reliable vehicle. :)
