Question

In the hydraulic braking system, the piston in the master cylinder is connected by mechanical linkage to the
A. Wheels cylinders
B. Brake shoes
C. Brake pedal
D. Wheel pedal

Answer 1

Hint: We will understand the hydraulic braking system's working, mainly when the brake is applied by the driver to stop the vehicle. The hydraulic braking system utilizes the conversion of pressure energy into work to stop the vehicle.

Complete step by step answer:
In a hydraulic braking system, the pressurized fluid's energy is utilized to transfer the brake pedal force to the wheel's brakes. The transfer of force occurs due to the conversion of pressure into useful work. The brake fluid present in the master cylinder is compressed due to the driver's effort on the brake pedal. The hydraulic fluid pressure is transferred equally to the rear wheel's cylinder piston and the front disc's piston.

In this type of braking system, the force of braking is linearly proportional to the ratio of the cross-sectional area of the master cylinder and the cross-sectional area of the cylinder of the drum brake wheel. Hence, this ratio is more significant while designing the braking system as the desired effect is directly proportional to it.

Therefore, in the hydraulic braking system, the piston in the master cylinder is connected by mechanical linkage to the brake pedal

So, the correct answer is “Option C”.

Note:
The fluid used in this hydraulic system is incompressible because we do not want to waste energy to compress the fluid. Also, there is no provision for air presence because if this happens then, the process of braking will become spongy. Seals are used to prevent leakage of hydraulic fluid. The friction in this system is only present between seals and cylinder pistons.
