Due to dust getting in between pads and rotor
Sounds like low pads. many have built in wear indicators that squeal to warn you.
Automatic transmission fluid does not squeal. You have a different problem. Brakes squeal, bearings squeal, and belts squeal. Fluids do not squeal. You had better take your vehicle to a mechanic.
At least inspect when you hear squeal. Base further work on what you see.
Disc brakes squeal due to vibrations between the brake pads and rotor. This issue can be resolved by ensuring proper installation and alignment of the brake components, using high-quality brake pads, and applying anti-squeal lubricant or shims.
When they have rust on them or you need new ones. Go have them looked at
first of all, the pads may be semi-metallic and have chunks of metal in them which may cause the squeal, change to a less metallic pad may help, also the backing of the pads should have an anti-squeal gel applied to them, when you apply the brakes, the pads will hyper vibrate and can cause a squeal. The gel will stop the vibrating. first of all, the pads may be semi-metallic and have chunks of metal in them which may cause the squeal, change to a less metallic pad may help, also the backing of the pads should have an anti-squeal gel applied to them, when you apply the brakes, the pads will hyper vibrate and can cause a squeal.

A disc brake squeal can occur even when not applying the brakes due to vibrations between the brake pads and rotor, which can be caused by factors like uneven wear, contamination, or improper installation.
