Question

Which of the following consists of a master cylinder filled with a thick oil?
(A) Hydraulic brakes
(B) Hydraulic jack
(C) Hydraulic press
(D) All of the above

Answer 1

The Hydraulic braking system uses brake fluids to transfer the pressure from the control mechanism to the braking mechanism. The Hydraulic brakes are used to stop and slow-moving systems. This braking system transfers pressure via the use of a braking fluid when they are triggered and this pressure triggers the braking mechanism.

Complete answer:
A hydraulic brake mainly consists of a master cylinder that is filled with a thick oil called the brake fluid.
Your brake pedal is connected to a mechanical part that is called a master cylinder, which is filled with brake fluid. The master cylinder pushes brake fluid through your brake lines to the wheels when you push on your brake pedal. Where it’s used to activate the hydraulic brakes when the fluid transmits the pressure via brake lines that go to each wheel.
The brake fluid is prevented from escaping between the pistons and cylinder walls by rubber pressure seals which serve the piston retraction springs, while dirt and moisture are kept out by flexible rubber dust covers.
Hence, the correct answer is hydraulic brakes, option (A).

Note:
Since the brake fluid also acts as a lubricant if the frictional loss at high-speed braking is reduced. Less thermal stress compared to Mechanical Braking is produced by the Hydraulic Brakes. The brake shoes may be ruined while the brake fluid leaks out. In the environment, High moisture can change the quality of the hydraulic fluid and cause corrosion of the internal components.
