what causes the grinding sound in your car wheels?

Sometimes when we drive our cars it is important we observe the sounds that the car makes or that is produce from the car.

one of such sound is the the grinding sound that it makes on your wheels, the sound is mostly to occur in cars that have disc brake on the front wheel (the rear wheel are mostly drum brake).

The likely cause of this  includes:
1. bad brake pad - you  easily identify a bad brake pad by observing the reduction in the pad

2. Un-tighten brake pad (loosen pad fittings) - as simple as this may look, this is a major reason why your brake pad may be making that grinding sound, when the fittings are not well positioned or the fittings are bad, the brake pad is not well positioned, this leads to the vibration of the brake pad, and the noise occurs.
