What component converts hydraulic pressure from the master cylinder to mechanical force?

The component that effectively converts hydraulic pressure from the master cylinder to mechanical force is the wheel cylinder. In a braking system, when the driver presses the brake pedal, the master cylinder generates hydraulic pressure. This pressure then travels through the brake lines to the wheel cylinders located at each wheel.

The wheel cylinder is designed to utilize this hydraulic pressure to push the brake shoes outwards, creating friction against the brake drum (in drum brake systems) or pushing the brake pads against the rotor (in disc brake systems). This conversion from hydraulic pressure to mechanical force is essential for slowing down or stopping the vehicle.

In contrast, the brake master is responsible for generating the hydraulic pressure itself, while the caliper works in conjunction with brake pads to clamp down on the rotor in disc brake systems, helping to create the necessary stopping force. The rotary drilled valve generally relates to different functions, often found in other parts of the system or as part of specific applications, but does not play a role in converting hydraulic pressure to mechanical force.
