probably not your engine, sounds like its time for new brake pads. if this doesnt correct it have the master brake cylinder checked
That depends on how, when and where it is squealing. For example, if the brakes squeal when applied, the brake pads are probably worn down. A squeal from the engine compartment whenever the engine is running could be a loose serpentine belt (especially if the squeal changes a little when you rev the engine).
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.
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.
bad brakes.
Sounds like it needs some lubrication. Try applying some graphite powder.
Sounds like low pads. many have built in wear indicators that squeal to warn you.
A slipping belt or some kind of air flow problem..
Brake squealing is commonly caused by worn brake pads. The metal part of the pad makes contact with the rotor, causing the noise.
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.
Due to dust getting in between pads and rotor
Maybe the tires? If it is in the engine compartment, it is probably either a loose belt or one is getting old and slipping.
