There are many other brake squeal questions but the symptoms in the case of my car are different.
After driving for about 5 miles, I hear loud squealing noises from the wheel wells when I turn right or I drive up a sloping road. The speed of the car does not make a difference. The noise goes away when I apply the brakes.
I took the car to the dealer and they said the brake pads were not getting worn uniformly because I go very easy on the brakes - apparently there is 8 mm still left on a brake pad of 10 mm thickness after driving 30k miles. They said if the brakes are always applied lightly, then the pads do not wear uniformly because all parts of the pad do not make contact with the rotor causing this squeal and that the noise would go away after some time if I start braking normally.
Does the dealer's explanation make sense? Is it a known fact that always braking lightly will cause the brake pad to not wear away uniformly causing a squeal? If so why does it squeal only when turning right or driving up a slope?
