Explain the working of a hydraulic disc brakes on which law it is based
Answers
Answer:
That's why brakes use hydraulics: a system of fluid-filled pipes that can multiply force and transmit it easily from one place to another. When you press on the brake pedal, your foot moves a lever that forces a piston into a long, narrow cylinder filled with hydraulic fluid.
Explanation:
Answer:
Hydraulic brakes are based on Pascal's law of transmission of pressure in liquids.
To apply brakes, the foot pedal is pressed due to which pressure is exerted on the liquid in the master cylinder P, so liquid runs out from the master cylinder P to the wheel cylinder Q. As a result, the pressure is equally transmitted and undiminished through the liquid to the Pistons B1 and B2 of the wheel cylinder because of which both Pistons get pushed outwards and brake shoes gets pressed against the rim of the wheel due to which the motion of the wheel retards.

When the pressure on the pedals is released, the liquid runs back from the wheel cylinder Q to the master cylinder P and the spring pulls the brake shoes to their original position and compels the Pistons B1 and B2 to return back into the wheel cylinder Q. Hence, brakes are released.
