Topic Synopsis
This topic covers the operation of vehicle suspension, steering, brakes, wheels, and tyres. Learners must understand how these systems work and be able to remove and fit related components safely.
Key Concepts & Core Principles
- Panel repair techniques: Understanding how to use tools like dollies, hammers, and slide hammers to reshape damaged body panels without causing further distortion. You'll learn methods such as planishing, shrinking, and stretching to restore panels to their original shape.
- Welding processes: Mastery of MIG (Metal Inert Gas) welding is crucial for joining steel panels. You'll also learn about spot welding and brazing, and how to set up welding equipment correctly to achieve strong, safe joints that meet industry standards.
- Paint preparation and application: This includes surface preparation (sanding, masking, and priming), mixing paint to manufacturer specifications, and using spray guns to apply basecoat and clearcoat. You'll also learn about colour matching and defect rectification.
- Vehicle dismantling and reassembly: Safely removing and refitting trim, mechanical components, and body panels without causing damage. This requires knowledge of fastener types, torque settings, and the use of specialized tools like trim removal kits.
- Health and safety in the workshop: Compliance with COSHH (Control of Substances Hazardous to Health) regulations, proper use of PPE (Personal Protective Equipment), and safe handling of hazardous materials such as paints, solvents, and welding gases.
Exam Tips & Revision Strategies
- Memorise key components and their functions.
- Practise removal and fitting under timed conditions.
- Use diagrams to reinforce understanding of systems.
Common Misconceptions & Mistakes to Avoid
- Incorrectly identifying component functions.
- Failing to follow torque settings or safety procedures.
- Mixing up components from different systems.
Examiner Marking Points
- Explains how suspension, steering, brakes, wheels, and tyres operate.
- Demonstrates safe removal and fitting of components.
- Follows manufacturer specifications and safety procedures.
- Identifies common faults and their causes.
