Regular brake maintenance is crucial for safety, and replacing worn brake pads and rotors can improve your vehicle's performance. This guide will provide you with step-by-step instructions, the necessary tools, and tips to ensure a successful brake replacement.

Step 1: Gather Your Tools and Safety Gear

Before starting the brake replacement, ensure you have all the necessary tools and safety equipment:

• Tools Needed:

  • 14mm Wrench
  • 14mm Socket
  • 21mm Socket
  • 22mm Socket
  • Brake Caliper Compressor Tool (Single Piston, Lever Style)
  • Brake Caliper Hanger
  • Large Locking Pliers
  • 1/2 Inch Impact Gun
  • 3/8 Inch Impact Gun
  • Ratchet
  • Torque Wrench
  • Wire Brush

• Safety Gear:

  • Gloves
  • Safety Glasses
  • Wheel Chocks
  • Floor Jack
  • Jack Stands

Step 2: Secure the Vehicle

1. Park the Vehicle: Ensure the vehicle is on a flat surface and in park mode (or gear for manual transmission).
2. Apply Wheel Chocks: Place wheel chocks behind the rear wheels to prevent movement.
3. Lift the Front of the Vehicle: Use the floor jack to lift the front of your Infiniti G35.
4. Insert Jack Stands: Once lifted, place jack stands securely under the vehicle to ensure stability.

Step 3: Remove the Wheel

1. Loosen Lug Nuts: Using the appropriate socket, loosen the lug nuts on the front wheel but do not completely remove them yet.
2. Take Off the Wheel: After lifting the vehicle, remove the lug nuts completely and take off the wheel.

Step 4: Remove the Brake Caliper

1. Locate the Caliper Bolts: Find the two bolts holding the brake caliper in place.
2. Remove the Bolts: Use the 14mm socket and ratchet to remove these bolts.
3. Hang the Caliper: Use a brake caliper hanger or large locking pliers to suspend the caliper from the suspension to avoid stressing the brake line.

Step 5: Remove the Old Brake Pads and Rotors

1. Take Out the Brake Pads: Slide the old brake pads out from the caliper bracket.
2. Remove the Brake Rotor: If the rotor is stuck, gently tap it with a hammer or use a wire brush to clean any rust or debris. Then, slide the rotor off the hub.

Step 6: Install New Brake Rotors

1. Position the New Rotor: Align the new rotor onto the hub and push it into place.
2. Secure the Rotor: If necessary, use the lug nuts to hold the rotor in place temporarily.

Step 7: Install New Brake Pads

1. Prepare New Pads: Apply brake grease to the backing of the new brake pads to prevent noise.
2. Insert the New Pads: Slide the new brake pads into the caliper bracket.

Step 8: Reinstall the Brake Caliper

1. Compress the Caliper Piston: Use the brake caliper compressor tool to push the caliper piston back into the caliper housing.
2. Reattach the Caliper: Position the caliper over the new brake pads and align it with the bracket. Secure it by tightening the caliper bolts with the 14mm socket.

Step 9: Reinstall the Wheel and Lower the Vehicle

1. Put the Wheel Back On: Align the wheel with the hub and hand-tighten the lug nuts.
2. Lower the Vehicle: Carefully remove the jack stands and lower the vehicle back to the ground using the floor jack.
3. Tighten Lug Nuts: Once the vehicle is on the ground, use the torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Conclusion

You've successfully replaced the front brakes on your 2003-2007 Infiniti G35. Regularly check your brakes and replace them as needed, typically every 50,000 miles, depending on driving conditions. If you experience any unusual noises or vibrations while driving, it may be time for another inspection. Always prioritize safety when performing maintenance on your vehicle.
