I don't hear any noise while driving other than a whistling noise.

Watch this link for a view.

I asked the guy, he said it might wear out completely soon, and you would hear squeaking sound. Haven't heard it yet. I hear a whistling sound though.

Also, the car has a problem that its revs fluctuate which give a small jerk, happens only when static not when in motion. Don't know the reason.
Tried cleaning the throttle, changing the spark plugs.

Hello,

Watching the video your main concern should be the tires for road safety. Replace these ASAP.

Looking at the brake discs, it is apparent that the brake pads seem to have hard spots/glazing which would cause the wear groves and could cause the whistling sound when braking. Brake pad thickness would indicate that they have about 20% life left, so a few thousand miles, depending on usage. see image 2 for an example of a glazed brake pad.

Glazed brake pads and resultant wear of the brake rotor can be caused by overheating.

Fluctuating idle could be caused by a possible intake air leak.
