there could be excessive clearance in the rear differential case if this is a rear wheel drive vehicle.
It sounds like wheel bearings. They make a noise while they're in one position but when you hit the brake, it moves them a little, and the noise stops.
you most likely have low brake fluid or if it stops fine its just an annoying noise
You need to check the brake pads to see if the brake pad shims are broke, missing or loose. This is most likely the source of your noise.
The brake pads are worn down. Many brake pads have a built in noise maker designed to squeal when the pads are nearing end of life.
Sounds like the power brake booster is bad. Get it checked out.
your keys?
Your vehicle may have a sticking brake; once you drive it, it unlocks; but this needs to be looked at before the brake is damaged. I hope this helps you. Mark
the squeeking noise is the " birdt chirpers " letting you know you need new brake pads.
it really is a vague discription. do you feel the tick in the gas pedal? does it sound like its coming from near your tires... or your engine? most likely it is a wheel bearing or bushing. if it becomes a knocking noise when you go around corners it is your constant velocity axle i am assuming your vehicle is a front wheel drive.
Whining noise near belts had pulleys adjusted any idea what is causing this
ABS stops your wheels from locking up when you brake which is very useful when driving in slippery conditions.
there are metal tabs on your brake pads that are designed to rub on the rotor and squeak to let you know the pads are getting thin and need to be replaced this is possibly what your noise is.
