your brakes are sticking need servicing asap
Your tires are worn out, or your accelerating too hard. Or is it only when you break? it means you need to replace our brakes, one side might be more worn out than another, so when you brake one side may get more grip and make it turn.
Check the brakes. You might have worn disk brake pads and if your vehicle has worn brake sensors, it can make that kind of sound.
A BAD Axle or Wheel Bearing.!!! Is that only happening while the brakes are applied, or all the time? It could be that the inner pads are worn down to the metal, and whoever checked the brakes, missed it. One only has to rub fingers on the back side of the rotor to confirm this. If the pads are not suare with the rotor, they will look good from the top, but will be cutting up the rotor at the bottom. If it makes the noise all the time, then you might have a wheel bearing out, or a tire breaking down/worn tread. When the brakes were checked did they check the bearings? is this sound coming only from the front? if heard in the rear as well check that the emergency brakes are not locking up.
Your brakes may have worn out from to much usage or the tires may be flat and the brakes can reach them
If your brakes are grinding at all, you need to inspect the brake pads. I suspect you will find your pads are worn out.
Your rear brakes (drum) are probably so worn out that the shoes are trying to rotate with the drum and lock up. There is an adjuster inside the drum & you might can tighten the shoes, but if they are that worn out, then replace the brake shoes.
Worn out brakes.
My car has only 122K mi on it. The pads are only about 1/2 worn out.
Worn caliper pistons, broken delivery lines.
No. You will only need to replace the brake shoes if they are worn down. Generally the front brakes do 70% of braking leaving the rear with 30%, which will cause the front pads to wear first. What is important however is that you replace either front brakes or rear brakes as a set. i.e. if you're replacing the front brakes do the right and left side.
Yes.... the brakes will make a "metallic" sound when the brakes are getting worn.
