To understand the four points of inspection, it’s important to know they refer to specific areas of a vehicle that are commonly checked during routine maintenance or safety inspections. These points ensure your vehicle is in safe, working condition. Let’s explore each point in detail and why they matter for vehicle safety and performance.

What Are the Four Points of Inspection?

The four points of inspection typically include the brakes, tires, lights, and fluids. These are critical areas that directly affect the safety and functionality of your vehicle. Ensuring these components are in good condition can prevent accidents and costly repairs.

1. Brakes

Brakes are perhaps the most crucial component for vehicle safety. Regular inspection of brakes includes checking brake pads, rotors, and brake fluid levels. Worn-out brake pads or low brake fluid can lead to brake failure.

• Brake Pads: Inspect for wear and tear. Replace if the thickness is less than a quarter of an inch.
• Rotors: Check for grooves or cracks. Resurface or replace if damaged.
• Brake Fluid: Ensure fluid is at the recommended level and free from contamination.

2. Tires

Tires are essential for maintaining traction and stability on the road. Regular tire inspections can prevent blowouts and improve fuel efficiency.

• Tread Depth: Ensure tires have at least 2/32 of an inch tread depth. Use a penny test to check.
• Air Pressure: Maintain the manufacturer’s recommended psi for optimal performance.
• Alignment and Balance: Check for uneven wear patterns, which can indicate alignment issues.

3. Lights

Proper lighting is vital for visibility and communication with other drivers. Inspect all vehicle lights to ensure they are functioning correctly.

• Headlights: Check for brightness and alignment. Replace bulbs if dim or burnt out.
• Brake Lights: Ensure all brake lights illuminate when the pedal is pressed.
• Turn Signals: Verify that all indicators are working and visible.

4. Fluids

Fluids are the lifeblood of your vehicle, keeping it running smoothly. Regularly check and top off all necessary fluids.

• Engine Oil: Change every 3,000 to 5,000 miles, depending on the vehicle and oil type.
• Coolant: Ensure levels are adequate to prevent overheating.
• Transmission Fluid: Check for proper level and color. Replace if burnt or discolored.

Why Are These Inspections Important?

Regular inspection of these four points can prevent unexpected breakdowns and maintain your vehicle’s longevity. By addressing issues early, you can avoid more significant problems down the road.

• Safety: Ensures the vehicle operates safely under various conditions.
• Cost-Effective: Prevents expensive repairs by identifying issues early.
• Performance: Maintains optimal vehicle performance and fuel efficiency.

Practical Tips for Vehicle Inspections

• Schedule regular maintenance checks, ideally every six months.
• Use a checklist to ensure all points are covered during inspections.
• Consult your vehicle’s manual for specific maintenance guidelines.
