$\huge \boxed{ \fcolorbox{red}{white}{Answer}}$

• Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible.

Answer 2

Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles and  It is used in transferring  force into pressure, and to amplify  the braking force. It works because liquids are not appreciably compressible.

Explanation:

At all the points in the fluid the pressure will remain constant which is at rest and fluid exerts equal pressure in all the  directions with respect to the pressure to  exerted on it.

Thus, the hydraulic fluid is used to operate the brakes in a car.
