Ford India — problem in replace of brake pad during regular service and making noise

I have a ford figo with middle version. I was regular to the service in every 10000 km. Now 50000 km crossed. There was a complaint in the break pad and replacing the same due to thinness during the service on 50000 km. However it makes noise in the front right side while driving in the irregular road. I went back to the center and recheck the same that there was a problem in fitting of break pad. But still i felt the same sound. I have a fear of, is that any problem while applying break?
