**Lesson Procedure:**
**Introduction (10 minutes)**
1. **Greeting and Attendance:** Greet students and take attendance.
2. **Hook:** Show a brief video clip or animation of a car braking, highlighting the importance of a properly functioning braking system. Engage students by asking them to share their experiences or knowledge about car brakes.
**Body (40 minutes)**
**1. Recap of Braking System I (5 minutes)**
- Quick review of the basics covered in the previous lesson (types of braking systems, basic functioning).
- Discussion questions to assess understanding.
**2. Components of a Braking System (10 minutes)**
- Use the whiteboard to draw and label a diagram of a typical hydraulic braking system.
- Introduce and explain each component (e.g., brake pedal, master cylinder, brake lines, calipers, brake pads, rotors/discs).
- Show real-life examples or models of these components for better understanding.
**3. Function of Each Component (10 minutes)**
- Explain the role of each component in the braking process.
- Detail how hydraulic pressure is created and transferred through the system.
- Highlight the interaction between brake pads and rotors to create friction and stop the vehicle.
**4. Working of Hydraulic Braking System (10 minutes)**
- Use the hydraulic fluid simulation kit to demonstrate how hydraulic brakes work.
- Show a step-by-step working process of how pressing the brake pedal translates into the vehicle slowing down.
- Answer any questions students may have about the process.
**5. Basic Maintenance and Troubleshooting (5 minutes)**
- Discuss common issues and signs of brake problems (e.g., squealing sounds, spongy brake pedal).
- Explain basic maintenance tips (e.g., checking brake fluid levels, inspecting brake pads and rotors for wear).
- Demonstrate the use of basic tools to perform simple brake maintenance tasks.
**Conclusion (10 minutes)**
- **Summary:** Summarize the key points covered during the lesson.
- **Questions and Answers:** Allow time for students to ask questions and clarify any doubts.
- **Assessment:** Distribute a short quiz or worksheet to assess understanding.
- **Homework Assignment:** Ask students to complete a written assignment on the importance of regular brake maintenance and the potential consequences of brake failure.
**Safety Tips Reminder:**
- Emphasize the importance of safety when working with automotive components.
- Remind students to always wear appropriate safety gear and follow proper procedures.
