@All: I have just returned from 3S Dealer after my car inspection. It was wheel alignment issue, they checked the brake pads etc but front right Tyre was causing most trouble.
Now its working fine. About the brakes I feel its getting better with passage of time, as today I feel significant different in brakes from last couple of days. May be the pads are news and getting more grip as they got used.
Anyways again thanks all who took their time and give suggestion.
