What is the air sound coming from the brakes?
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.
What is a hissing sound coming from the drivers side of your Mercedes ML350?
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

What is wrong when a Jeep is making an air hissing sound when it is running but quiets when you apply the brakes?
This sounds like the power brake vacuum booster going bad.
Why would air release when you press on the brakes?
Do you drive a tractor trailer (semi) with air brakes? where is the air coming from when you notice this. This person's probably talking about a car......It is atmospheric pressure entering the vacuum booster, the air rushing past the valves inside.
How do you hear the sound coming from a drum?
Through sound waves travelling as vibrations through the air.
Do air brakes work instantly like hydraulic brakes?
Yes they do, and they feel about the same to the operator of the vehicle.
Why does it sound like air is seeping out when I press my brake pedal on my 1997 Chevy Tahoe.?
The power brakes on most vehicles operate on the engine vacuum. If there is a leak or problems with the power brakes it can make a hissing sound. But then, sometimes power brakes do that when they're working properly. It could be from either a hole in the diaphragm of the brake booster or normal operation. If the sound is new, and was not there before, and your brake pedal is going to the floor, then you should have the power booster replaced.
Do sound waves vibrate the air?
No. Vibrating air IS sound waves. With no atmosphere (no air, like in space), there are no sound waves.
Do air brakes use brake fluid?
No, they use air pressure or actually the lack of air pressure to stop the vehicle. The brakes are fully on until pressure builds up in the tank releasing the brakes. When you push the brake pedal this removes air from the system and applies the brakes.
How do you adjust brake imbalanced?
We would need to know what type of brakes you have... S-cam air brakes, air disc brakes, air piston brakes, air wedge brakes, hydraulic drum brakes, hydraulic disc brakes... they're all different.
