Q. The main function of a master cylinder is to

1. Adjust the extent of brake pedal free play
2. Boost the force applied to the brake pedal
3. Convert brake pedal force into hydraulic pressure
4. Ensure that all the wheel brakes are supplied with the same amount of fluid pressure

Answer: Convert brake pedal force into hydraulic pressure.

The main function of a master cylinder is to convert brake pedal force into hydraulic pressure.

In automotive engineering, the master cylinder is a control device that converts force (commonly from a driver's foot) into hydraulic pressure. This device controls slave cylinders located at the other end of the hydraulic system.

The principle of working is that of Pascal’s Law where a high-pressure fluid is obtained at the outlet of smaller area, of a cylinder by application of force on the larger area inlet area.

Master brake cylinders are used both in disc brakes and drum brakes.
