My car is a 2006 model Infiniti G35. Actually, I bought it from a private dealer 3 months back. At that time I had a complete checkup and replaced the brake calipers and rotors. After that, I didn't use the vehicle for long drives. But now there has some noise while braking. I read one blog related to this here http://www.serviceplus416.com/maintenance-tips/how-to-diagnose-brake-noises/. From that, I came to know about the various reasons behind this noise. But I already had a complete brake service before 1500 km. Then how can this happen? I don't know about the actual reason. Can somebody help me with some suggestions?
