Two "most likely" reasons that are most likely.
A small piece of dirt or sand trapped between the pad and rotor often causes high pitched noise such as squeaks or squealing, sometimes a harsh bang on the brake pedal when driving may either loosen or melt the dirt and relieve your noise.
Make VERY sure you are able to do this in a safe area at safe speeds.
The second reason could be related to brake pads that are worn down to the wear sensor, the thin piece of metal that is designed to create that annoying noise when they rub on the rotor.
Both these two items MAY vary or go away when you either release or apply the brake
Pads that are metal on metal usually generate a grinding noise on brake apply not simply a squeal.
It could squeal, squeak, moan, whine, groan, and leak oil.It could squeal, squeak, moan, whine, groan, and leak oil.
Large pigs do not squeak, they squeal, Guinea Pigs will squeak.
That could be the brake pad "squealers". They are designed to squeal when they are worn out. Time for a brake job.
it could be the breaks, or the shock could be hitting against the wheel
the right because it is getting the full weight of centrifugal force on it it will tend to slip hence the squeal
A faulty bearing wil initially squeak or squeal. Eventually it will shriek, and then it will seize up. Better to have it checked out now, before you are stranded.
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
You are describing a squeak, or a squeal.
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.
Generally new pads will contain a layer of dust which causes the initial squealing. The squeal should go away after a bit if driving.
If you didn't turn the rotors (have them ground to give a smooth, even surface), the uneven rotor face on the new pads may squeal.
Do you have excessively worn brake linings? Thanks for the suggestion! I considered it but thought the brake linings would only squeal when braking? What I'm experiencing happens while I'm on the gas. Please let me know if I am mistaken. Thanks!
