Name and state the principal on which the hydraulic brakes of a car works.

Explanation

**Step-by-Step Solution:**

1. **Identify the Principle**: The hydraulic brakes of a car operate based on a specific principle. The principle that governs the functioning of hydraulic brakes is known as Pascal's Law.

2. **State Pascal's Law**: According to Pascal's Law, when pressure is applied to a confined fluid, that pressure is transmitted undiminished in all directions throughout the fluid.

3. **Application of Pascal's Law in Hydraulic Brakes**:
- When the driver presses the brake pedal, a force is applied to a small piston in the brake system.
