Usually because of wear, a disk brake system typically has a squealer that with contact with the rotor will make a squeaking sound telling you its time to change the brakes..some have no squealer and the sound is coming form the rivets on the pads making contact with the rotor..ie past time to change..If the brake pads have been changed or are in fine shape and there is a squeak it is because there is no anti squeal compound on the back side of the pads.
It is most likely that the cars brakes are bad.
you need new brakes
did you put high quality brakes on your car if so then it is normal do not worry about it. even if not some brakes just squeak all the time
The friction between 2 objects makes them squeak
The car may need new brakes or tires because they might be wearing down.
Can you give more detail? Is it squeak, squeak, squeak or squeeeeeeek? I'm assuming that it only occurs when the car is moving. Does putting the brakes on make it change? --Ken It does make squeeeeek sound when car is moving and putting brakes on does change it.
you can tell when your breaks start to Squeak or the car wont slow down when turning
you have a squeaky fanbelt..it either needs replacing or oiling
Some manufactures use a wear indicator that causes a squealing sound when the pads need to be replaced.
Because You Need New Brakes!
No
The brakes can squeak, the suspension can squeak, the steering can squeak, the wheel hub/bearings can squeak, have a trusted mechanic determine the source of the squeak.
