The Special Hydraulic Fluid called Brake Fluid is used for several reasons:
Hydraulic oil and hydraulic fluid are different. Hydraulic fluid is used in small systems such as car brakes. Hydraulic oil is used in large systems such as loaders.
mechanical and hydraulic are two different power transmission medium. in mechanical brakes solid links or levers are used to achieve the required braking. in hydraulic brakes there are no links, here the braking is achieved by the hydraulic fluid, the hydraulic system in which the force applied at the brake pedal is multiplied several times to achieve the requied braking.
hydraulic oil
It was 1939 that Ford started to use hydraulic brakes.
Instead of using hydraulic brake fluid to apply the pads to the brake drums or discs, air pressure is used.
Because air is in constant supply - thus, a leak in the system won't necessarily render the brakes inoperable, whereas, with hydraulic brakes, the fluid would leak out until it had emptied.
In some cases, yes but NOT for hydraulic BRAKE fluid.
DOT ( 3 ) brake fluid is used for the hydraulic clutch and the brakes in a 1997 Ford Explorer Sport
A hydraulic system uses pressure to create movement. Hydraulic systems operate by transmitting force through a fluid, usually oil, which is pressurized within a closed system and then used to move components like cylinders or motors. This technology is commonly used in applications like construction equipment, automotive brakes, and airplane flight controls.
A car has to have brake fluid to allow for the effective operation of the brakes to stop the car. When we apply pressure to the brake pedal, brake fluid, which is largely incompressible, will transfer that pressure to the pistons that operate the in the calipers or the pistons that operate the brake shoes. Further, the fluid must be of the correct type for the system in which it is used. The continued safe operation of the brakes may be compromised by the wrong fluid.
A hydraulic motor uses hydraulic pressure to drive it. Simplest hydraulic motor is a water wheel which uses a directed water stream to move it. Hydraulic motors are used to operate other equipment directly. A hydraulic pump on the other hand is used to move hydraulic fluid for use elsewhere. Hydraulic pumps are powered by motors or engines and are not used to operate other equipment directly. Internally pumps and motors are quite different and cannot typically be interchanged.
Three examples of hydraulics include hydraulic brakes in vehicles, which use fluid pressure to amplify force for stopping; hydraulic lifts, such as those used in car repair shops, which raise heavy objects using fluid pressure; and hydraulic excavators, which employ hydraulic systems to control the movement of their arms and buckets for digging and lifting. These applications demonstrate the principles of fluid mechanics in practical, everyday uses.
