Introduction

This tutorial will guide you through the process of replacing the front brake pads and rotors on an Infiniti G37 (model years 2008-2010). Performing this maintenance task can improve your vehicle's braking performance and extend the lifespan of your brake system. Follow these steps carefully to ensure a successful DIY project.

Step 1: Gather Necessary Tools and Materials

Before starting, make sure you have the following tools and materials ready:

• New brake pads
• New brake rotors
• Lug wrench
• Jack and jack stands
• Brake cleaner
• C-clamp or brake caliper tool
• Torque wrench
• Socket set
• Screwdriver

Practical Tips

• Wear safety gloves and goggles to protect yourself.
• Make sure your car is parked on a flat surface and the engine is off.

Step 2: Remove the Wheel

1. Loosen the lug nuts on the front wheel using a lug wrench.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Completely remove the lug nuts and take off the wheel.

Common Pitfalls

• Do not rely solely on the jack for support; always use jack stands.

Step 3: Remove the Brake Caliper

1. Locate the caliper bolts on the back of the brake caliper.
2. Use a socket wrench to remove these bolts.
3. Carefully slide the caliper off the rotor. Do not let it hang by the brake line; use a bungee cord or similar to support it.

Practical Tips

• If the caliper is stuck, gently tap it with a rubber mallet.

Step 4: Replace the Brake Pads

1. Remove the old brake pads from the caliper bracket.
2. Compare the old pads with the new pads to ensure they match.
3. Install the new brake pads into the caliper bracket.

Step 5: Replace the Brake Rotor

1. Remove the retaining screws (if applicable) holding the rotor in place.
2. Slide the old rotor off the hub. If it’s stuck, gently tap it with a mallet.
3. Clean the hub surface with brake cleaner before installing the new rotor.
4. Place the new rotor onto the hub.

Real-World Applications

• Always check for rust or debris on the hub, as it may affect rotor installation.

Step 6: Reinstall the Brake Caliper

1. Compress the caliper piston using a C-clamp or brake caliper tool.
2. Position the caliper over the new pads and rotor.
3. Reinsert and tighten the caliper bolts securely.

Step 7: Reattach the Wheel

1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts onto the wheel.
3. Lower the vehicle and then use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Practical Tips

• Always tighten lug nuts in a star pattern for even distribution.

Conclusion

You have successfully replaced the front brake pads and rotors on your Infiniti G37. Regular maintenance of your brake system is crucial for safe driving. Remember to test the brakes gently after replacement to ensure everything is functioning correctly. Consider scheduling regular inspections for other components of your vehicle's braking system to maintain optimal performance.
