i would say that it is brake dust build up or that the sliders on the calipers need to be lubed and check the bridges where the pads meet lube that to also what kind of pads are you using matalic pads make miore noise hope that helps
Your brakes are telling you they need replacing soon. They have a built in "squealer" designed to make a noise when the pad wear is nearing the end.
bad brakes.
Sounds like low pads. many have built in wear indicators that squeal to warn you.
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).
Wishful thinking, as a trapped mouse is cheaper than getting a garage to sort your brakes out - probably the pads need replacing.
A slipping belt or some kind of air flow problem..
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.
The squeal is a warning device installed on your vehicle telling you that your brake pads are worn out. The light is coming on because you have a problem. Have your braking system inspected ASAP. Do not ignore this or you will end up replacing the rotors and spending more money. You may also end up having an accident due to defective brakes.
If they squeal or make hard noises, or if your brakes are spongy or don't work then they need replacing. Or at least a simple servicing like repair or cleaning.
At least inspect when you hear squeal. Base further work on what you see.
It is wishful thinking. It is more likely your brake pads are worn down and need replacing - an expensive garage job!
probably not your engine, sounds like its time for new brake pads. if this doesnt correct it have the master brake cylinder checked
