Guys i dont know how to explain my problem but still i will try to explain you the situation. couple of weeks back i replaced my 2008 brake pads easy task half an hour job everything was normal good braking, no sounds from the pads etc.
Now problem time, sometimes i feel a very loud Hmmmmmm sound and vibration in my car while driving, now the problem is that i myself dont know when that sound will come and which part is making that sound, got checked the whole brake assembly apparently nothing looked bad. I personally feel metal rubbing against metal. to be more precise the sound is more like our local train stopping sound. :o
Now just trying my luck to get your feedback, otherwise there are no issues in the car everything is just fine.
