This usually means that the brake pads are wearing down- you may also notice that she doesn't respond so well to braking either. For safety's sake (your own, your cars', and other motorists & pedestrians) get the brake shoes changed as soon as possible.
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.
The squeaky noise from your bike brakes when you apply them is likely due to dirt or debris on the brake pads or rims, causing friction. Cleaning the brake pads and rims can help reduce the noise.
warped rotors , brake
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.
rumble
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.
either your hand brake has got something wrong with it and is stickingm, so that makes your tires rub against the road which makes a horrible noise!
The power brake booster may be going bad.
If you are not losing brake fluid I would say the master cylinder is bad. Can you tell what direction the occasional noise is coming from?
pulsating effect The Abs equipped cars do this naturally older cars with abs you will notice it more so than newer models.. If it just started occurring there may be a problem in the braking system. if it feels as if you are going over rumble strips (without the noise) when you brake first suspect would be a warped rotor.
brake linings may need replacing .that is first place tocheck and check em before the noise gets worse
The squealing noise from your bike's disc brake when pressure is applied is likely caused by vibrations between the brake pads and the rotor. This can happen due to uneven wear on the brake pads, contamination on the rotor or pads, or improper alignment of the brake caliper. Regular maintenance and adjustments can help reduce or eliminate the squealing noise.
