Introduction to Steering and Suspension — SEG Awards Vocational Motor Vehicle & Transport

The SEG Awards Level 1 Diploma in Motor Vehicle Studies introduces you to the fundamental principles of vehicle maintenance and repair. This qualification covers essential topics such as vehicle construction, engine systems, braking systems, steering and suspension, and electrical systems. You will learn how to safely use tools and equipment, interpret technical information, and perform basic servicing tasks. This diploma provides a solid foundation for further study or entry-level roles in the motor vehicle industry.

Understanding motor vehicle systems is crucial for anyone aspiring to work in the automotive sector. The course emphasizes health and safety practices, including the correct use of personal protective equipment (PPE) and safe handling of hazardous materials. You will develop practical skills through hands-on tasks, such as checking fluid levels, replacing brake pads, and inspecting tyres. These skills are directly applicable to real-world scenarios, preparing you for apprenticeships or employment in garages and dealerships.

This diploma fits into the wider subject of Motor Vehicle & Transport by providing a stepping stone to higher-level qualifications, such as the Level 2 Diploma in Light Vehicle Maintenance and Repair. It also aligns with industry standards set by the Institute of the Motor Industry (IMI), ensuring that the knowledge and skills you gain are recognized by employers. By mastering the basics, you will be well-equipped to progress in this dynamic and rewarding field.

• →Vehicle construction: Understand the main components of a vehicle, including the chassis, body, engine, transmission, and suspension systems.
• →Engine systems: Learn the four-stroke cycle (intake, compression, power, exhaust) and the function of key parts like pistons, valves, and crankshaft.
• →Braking systems: Know the difference between disc and drum brakes, and how hydraulic pressure is used to apply braking force.
• →Electrical systems: Grasp the basics of batteries, alternators, and starter motors, as well as simple circuits and wiring diagrams.
• →Health and safety: Always follow safe working practices, including using PPE, lifting equipment correctly, and disposing of waste oil and other hazardous materials properly.

• Award credit for demonstrating correct use of personal protective equipment (PPE) and following workshop safety rules
• Award credit for correctly identifying torque settings and using appropriate tools when removing and replacing wheels
• Award credit for accurately naming steering components such as steering wheel, column, rack and pinion, and tie rods
• Award credit for accurately naming suspension components such as springs, shock absorbers, and control arms
• Award credit for explaining the function of steering and suspension systems in vehicle control and ride comfort
• Award credit for identifying correct disposal methods for used tires, oils, and other hazardous materials

• 💡Always refer to the manufacturer's guidelines for torque settings and procedures
• 💡Use diagrams to label steering and suspension components clearly
• 💡Remember to mention environmental regulations such as the Waste Electrical and Electronic Equipment (WEEE) directive and proper disposal of tires
• 💡In practical assessments, demonstrate safe practice at all times, including wearing PPE and using correct lifting equipment
• 💡When answering questions about engine systems, always refer to the four-stroke cycle in the correct order: intake, compression, power, exhaust. Use diagrams to label parts like the spark plug, valves, and piston.
• 💡For practical assessments, demonstrate safe working practices throughout. For example, when jacking up a vehicle, always use axle stands and never work under a car supported only by a jack.
• 💡In written exams, use technical terms correctly (e.g., 'caliper' not 'clamp') and show your working for calculations, such as converting tyre pressure from psi to bar.

• Failing to use axle stands or wheel chocks when raising a vehicle
• Overtightening or under-tightening wheel nuts, ignoring torque specifications
• Confusing steering and suspension components, e.g., calling a shock absorber a strut
• Not considering environmental impact when disposing of old parts or fluids
• Misconception: The battery is the only source of electrical power in a vehicle. Correction: While the battery provides initial power, the alternator generates electricity once the engine is running to recharge the battery and power electrical systems.
• Misconception: Brake fluid never needs changing. Correction: Brake fluid is hygroscopic, meaning it absorbs moisture over time, which can lower its boiling point and reduce braking efficiency. It should be replaced according to the manufacturer's schedule.
• Misconception: Tyre pressure is only important for fuel economy. Correction: Incorrect tyre pressure also affects handling, braking distance, and tyre wear, and can lead to blowouts. Always check pressure when tyres are cold.
