Could be your brakes. If you have drum brakes not disk brakes that sound will happen when your shoes are worn down to the rivets. Some of the hardware such as springs, may have came off as well, which will make the loose metal sound.
Could be the brakes are metal to metal.
Check if muffler is loose, check if rear brakes are worn out & grinding
Your pads sound low-it's the wear indicators or you have metal-metal contact.
The grinding sound means that the brake pads are worn down to metal and that sound you hear is metal to metal. you need to have the pads changed, the problem is that you will more than likely have to change the rotors also. The way to avoid this in the future is when you notice your brakes are making a squealing sound that means that the pads will need to be changed soon.
The squealing sound you hear when your car brakes are wearing out is referred to as a "squealer." This indicator is a strip of metal that when the brake pad wears down makes contact with the rotor making a metal on metal noise.
Sounds like you need new brakes. When they get worn down they make a metal on metal sound.
That sound it the air being aloud to escape from the air system though the quick release valve. This usally happens when the driver has applied the parking brakes. But, it can happen during other times you dont want it to.
The sound is most likely the brakes squealing. Check the pads to make sure that the metal part isn't cutting into the rotor.
You may need to check your brakes or the rollers on your brakes
Typical sound of Tin if a metal bar is bent. This screaming of Tin is coming from the friction/ shearing of the metal crystals.
A knocking sound while your car is moving is probably coming from the engine. A certified mechanic will be able to perform diagnostic testing.
Get your brakes tested. I do not know what a ticking sound means.
brake booster could be bad the seal around the rod that hooks to the brake pedal is leaking
I hope you take it to a garage and have the brakes inspected. Might be a brake fluid leak.
have the back brakes checked sometimes they can sound like the front
It means it is time to have your brakes checked.
Yes.... the brakes will make a "metallic" sound when the brakes are getting worn.
One of the components in your rear drum brakes (or disc brakes) could have come loose, but that could be just one of the possible problems. Does the clicking sound more like two metal balls tapping together?...you know, like the ones people have in their offices at work, and they tap back and fourth? The problem could be your rear drive axle, rear suspension or your brakes. I am unable to be more specific because i would need to know what the clicking sounds like. The cost of repair could be 100 bucks if its the brakes, all the way up to 1,000 if its the axle.
It could be that the back tires brakes are rusted and need new replacements or just need oil.
Generally, squealing while NOT applying the brakes is the "chirper" or the metal tang rubbing the rotor. Typically, applying light pressure to the brake petal will make the squeal or chirping sound stop. This means your brake pad lining is thin and about to wear out.If you hear/feel a "scrubbing" sound while applying the brakes, generally the lining has worn away enough that some of the backing plate of the brake pad is rubbing on your rotor... This is BAD!Changing brake pads on disc brakes is one of the easiest repairs you can make to your automobile. Most automotive parts stores have 'lifetime warranted' pads, so you buy them once and every replacement afterwards is free. Of course, your labor is not included...However, brakes are a safety issue and you are not mechanically inclined or little or no experience, please consult a qualified mechanic.
Just know that if that is happening you are in serious trouble as it means that your brakes are leaking. In MLs the brakes use air pressure so if there is a hissing sound it means air is leaking thus your brakes could possibly fail. The best solution is to go to a registered Mercedes Benz garage so they can fix the problem. Alternatively if you dont have the money you could pretend that there is no noise and eventually you brakes will fail and you'll be in an accident i.e. GET YOU BRAKES FIXED AS SOON AS POSSIBLE
When motorcycle brakes lock, they make a light grinding sound accompanied by the loud screeching of the tires. When the brakes lock, the tires are forced to slide along the pavement until the brakes are released on the bike stops.
that could be a wheel bearing that's gone bad.
your brakes are about to give out... you should go to wal-mart and have them replace them
