Apply the parking brake,but not the driving brake, is the noise there? apply the brake,if the noise is only present when the brake is applied I would assume it is the anti-lock brake system. Get your VIN # of the vehicle and call a ford dealer and give them the # and ask if there are recalls for your vehicle. There are a few for this one but it depends on the vin. There is a anti-lock brake recall, but as I said it depends on where it was made if it falls under the recall.
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.
if it only does it when you apply the brakes hard it could be the anti-lock brake system depending on the year some have a pump and its noise is what is described. The other possability is front disk brake pads are worn off and and gringing away the rotor.
That wheezing noise could be a sign of a respiratory (breathing) infection, Which can become serious and if not treated fatal.
When you're brake pads be calm worn, they will have a slight shimmy when you apply the brakes. When the brake pads are completely worn out they will make a grinding noise.
You may have a brake booster that is leaking. The diaphragm may be busted. You will need to remove the brake booster vacuum hose and do a vacuum bleed down test. If the booster will not hold vacuum it needs replacing.
When Exhaust brake is on squeak noise comes from the engine?"
Check the brake pads. The most common cause of the noise is the pad backer grinding against the brake rotor.
They are equipped with a "telltale" warning that shrieks when the brakes are applied, with the brake pads are too low and need replacing.
A vibrating brake pedal is an indication of a warped rotor. Noise is common to disk brakes but depending on the noise it can mean that the brake pads are worn out and you are due for a brake job.
If you mean a "GRINDING" noise - then it sounds like the constant velocity joint (CV joint) may be failing -OR- if it only happens when you apply the brakes - the brake pad(s) need replacing.
you most likely have low brake fluid or if it stops fine its just an annoying noise
