Inspect your brake pads. I would suspect they are worn out.
There is afew things that can make it squeal like the belt is worn and old or power steering fluid low or pump going out.
Possible worn out brakes
In my experience this would be because the alternator belt needs to be tightned.
Your alternator is bad.
I would replace them, There probably worn out. Once they get alot of miles on them they get a coating also that makes them squeal.
A loose or glazed "fan belt" is a very common cause of squealing. A quieter squeal is produced by brake linings that are almost worn through.
glazing of the belt may cause that noise time to replace,little bit of dish soap will take it away
i bet he would get a wig.
WHHEEEEEEEEEEEEEEEEEEEEEEEEEEEK!
ignition of food or cooking materials
Exhaust vibration or loose mount, bad bearing on 1 of the accessories, loose belt squeal, if it's ticking-valvetrain with low oil.
