What do air brakes use to make the brakes work?

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.

Why use air brake in heavy equipment?

Air brakes allow you to use less force when hitting the brakes. Heavy equipment takes a lot of force to make them stop and without the air brakes we would have to use a lot of strength in order to stop the vehicle.

What is The air brake system on tractor trailer?

It's a dual circuit air brake system. Most use S-cam foundation brakes, although some use disc brakes or piston brakes.

Do you add coolant or freon to make a cars air conditioner work?

you use freon to cool your car and make the air conditioner work

How do people use fluid technologies?

People use it for their plumbing, the air brakes on trucks, hydraulics, etc.

Why is liquid useful for making brakes work?

It is not useful because if the liquid run out the car can't stop but if you use air than it is useful as when the air runs out there automatically comes more

Why transports use air brakes?

Because there is no risk of fluid loss - air is in constant supply.

The brakes take two minutes to release on your 1977 ford f700 dump truck with air brakes?

The release springs are hanging-up or you don't have sufficeint air pressure built-up or have air line blockage. Do you drain your air -tanks regularely? After each use . Water in air brakes can cause rust and will hang the brakes - up

Why only air is used in air brakes not any other solid?

Well, they wouldn't be air brakes then, would they? The reasons for air is that it's in steady supply, and a leak in the system doesn't cause you to use your supply.

Why is a liquid used in a car's braking system?

A liquid is used because it cannot be compressed. Remember the scientific qualities of the three states of matter. Solids have a definite shape and volume. Liquids have a definite volume, but not a definite shape. Gases can not only take the shape of a container like liquids, but with compression, a wide variety of different volumes of gas can fit into the same sized container. Now, you want a 1:1 relationship with the medium in the brake lines and for it not to compress. The reason you bleed the brakes is to get the air out so the brakes won't be spongy, since any air in the lines can be compressed. As hard as the brakes are to operate, a significant amount of air would mean that nothing would happen when you press the brakes. The air would absorb the pressure and the fluid past the air would never get the necessary amount of pressure to operate the brakes. Now trucks do use air brakes, but the system is too bulky to be practical in cars, and not as responsive. They employ a number of workarounds and tricks to make the system work. For instance, most brakes in tractor-trailers require air to release, not apply. That way, they can be much more responsive, since they are operated by heavy springs and the air fights the pressure of the springs. So the brakes are not always prompt in releasing. For the brakes to work in the trailer, there is a relay system, where a separate air tank under the trailer is kept charged, and thus the lines from the truck signal when to use the air from that tank. That is because the distance from the auxiliary tank under the trailer is much closer to the trailer air brakes than to the air tank in the truck.

If my brakes don't work can I use my emergency brake instead?

No. The emergency brake uses the same brakes. It'll be equally ineffective.

Do wet brakes make noise when they are in use?

Yes, wet brakes can make noise when they are in use due to the water on the brake pads causing friction and potentially creating a squealing or grinding sound.
