You've got it all wrong, liquids can't be compressed - only pressurized. Gases OTOH can be compressed. It's like the difference between poking at something with a stiff rod, or with a sponge. With a liquid, whatever force you put in at one end is what you get out at the other - just what you want if you're planning to build a closely controlled system like brakes.

How do liquids in hydraulic brakes help stop an automobile?

Liquids in hydraulic brakes help to stop an automobile by creating pressure and moving a set of pistons to generate force. This force is applied outward and causes friction that stops the automobile.

What is air over hydraulic brakes?

Air over hydraulic brakes are a braking system commonly found in heavy vehicles, such as trucks and trailers. This system uses compressed air to operate a hydraulic mechanism, allowing for powerful braking without relying solely on hydraulic fluid pressure. When the driver applies the brake, air pressure is generated, which then activates hydraulic cylinders to apply the brakes. This design helps improve brake performance and reliability, especially in larger vehicles.


Why are gases less useful than liquids in hydraulic brakes?

It's because liquids can't be compressed - only pressurized. Gases OTOH can be compressed. It's like the difference between poking at something with a stiff rod, or with a sponge. With a liquid, whatever force you put in at one end is what you get out at the other - just what you want if you're planning to build a closely controlled system like brakes.If you have gas, it'll be like having a big soft sponge between you and whatever it is that you are pushing on. First push will only squish up the sponge w/o anything happening to the object. Only when you've compressed the sponge will the object begin to move. And then when you stop pushing, the springiness in the sponge will keep pushing a bit. This is gases and pneumatics, not what you want in a closely controlled system like brakes.Gases compress. Liquids, in a hydraulic brake system, don't compress. A liquid-filled hydraulic brake system will produce more force on the wheel cylinder than one with a gas-liquid mixture.

How do cable actuated hydraulic disc brakes differ from traditional hydraulic disc brakes in terms of performance and maintenance?

Cable actuated hydraulic disc brakes use a cable to activate the hydraulic system, while traditional hydraulic disc brakes are activated directly by hydraulic fluid. Cable actuated brakes may require more frequent adjustments and maintenance compared to traditional hydraulic brakes, which typically offer better performance and require less maintenance in the long run.


Are bicycle brakes considered as hydraulic action?

depends on the type. There are hydraulic bike brakes, but most are mechanical.


Are disic brakes the same as hydrolic brakes?

No. Hydraulic brakes can be either drum or disc brakes, and these two brake types are available as air brakes and air-over-hydraulic systems, as well.


Why are liquids used in hydraulic brakes?

Because liquids can't be compressed - only pressurized. With a liquid, whatever force you put in at one end is what you get out at the other providing the piston connected to your break pedal is the same size as the one on the break assembly. If you press down with a force of 10 lbs. on a piston with an area of 1 sq inch (10 lbs/sq inch) and connect it to a piston with an area of 100 sq. inches, the resultant force will be 1000 pounds of pressure.


Was it 1938 or 1939 that Ford first used hydraulic brakes?

What is the recommended type of hydraulic mineral oil to use with Shimano hydraulic brakes?

The recommended type of hydraulic mineral oil to use with Shimano hydraulic brakes is Shimano Mineral Oil.


Is a bicycle an hydraulic machine?

Depends. Most bikes don't have any hydraulic components, but some have hydraulic brakes. Usually disc brakes, but there are at least two models of hydraulic rim brakes as well. And it could easily be argued that suspension bikes with oil shocks are hydraulic in design.
