Basic Knowledge and Tools Required for DIY Brake Replacement ===
Replacing the brake pads on your Infiniti G35 is a task that may seem daunting at first, but with the right knowledge and tools, it can be a rewarding and cost-saving experience. Before diving into the step-by-step guide, it is important to have a basic understanding of how the braking system works and the tools you will need for the job.
The braking system of your Infiniti G35 consists of several components, including the brake pads, calipers, rotors, and brake lines. The brake pads are the part that makes contact with the rotor, creating the friction needed to slow down or stop the vehicle. It is crucial to replace worn-out brake pads to maintain optimal braking performance and ensure the safety of you and your passengers.
To replace the brake pads on your Infiniti G35, you will need a few essential tools such as a jack and jack stands, lug wrench, socket set, C-clamp, brake cleaner, and a torque wrench. It is also recommended to have a service manual specific to your vehicle model, as it provides detailed instructions and specifications for the brake replacement process.
Before starting the DIY brake replacement, make sure you have all the necessary tools readily available, as well as a clean and well-lit workspace. Additionally, it is advisable to wear protective gloves and eye goggles to ensure personal safety throughout the procedure.
=== Step 1: Preparation: How to Safely Jack Up and Secure the Infiniti G35 ===
Before diving into the brake pad replacement, it is crucial to prepare your Infiniti G35 by safely jacking up and securing the vehicle. Start by finding a level surface to park the car and engage the parking brake. Loosen the lug nuts of the wheels you will be working on, but do not remove them just yet.
Next, locate the vehicle’s designated jack points, which are typically indicated by small notches or arrows on the underside of the car. Use a hydraulic floor jack to lift the car until the wheels are off the ground, and then place jack stands securely under the frame or designated jack points. Slowly lower the vehicle onto the jack stands, ensuring stability and safety.
Once the car is securely elevated, fully remove the lug nuts and carefully slide off the wheels. You are now ready to proceed with the brake pad replacement.
=== Step 2: Removing the Old Brake Pads: Detailed Instructions and Tips ===
With the wheels removed, you can now access the brake calipers and remove the old brake pads. Start by locating the caliper bolts, which secure the caliper to the bracket. Using a socket wrench, loosen and remove these bolts, being cautious not to damage the brake line attached to the caliper.
Gently slide the caliper off the rotor, and you will now have access to the brake pads. The pads are held in place by retaining clips, pins, or springs, depending on the specific model of your Infiniti G35. Carefully remove these retaining clips or pins, and take note of their positioning for later reassembly.
Now, you can easily remove the old brake pads from the caliper bracket. They may slide out effortlessly or require slight prying with a flathead screwdriver. Take this opportunity to inspect the condition of the brake hardware, such as the shims and anti-rattle clips. If worn or damaged, it is recommended to replace them with new ones for optimal performance.
=== Step 3: Inspecting and Cleaning the Brake Calipers: Why It’s Important ===
Before installing the new brake pads, it is crucial to inspect and clean the brake calipers thoroughly. Over time, brake dust and debris can accumulate on the calipers, hindering their proper functioning and causing premature wear of the new brake pads.
Inspect the caliper pistons for any signs of damage or corrosion. They should move smoothly and evenly when pushed in and out. If any issues are detected, it is advisable to consult a professional for further examination and possible repairs.
To clean the brake calipers, use a brake cleaner and a soft brush to remove any dirt, rust, or debris. Pay close attention to the piston area, as well as the caliper slides and guide pins if applicable. Once the calipers are thoroughly cleaned, allow them to air dry or use compressed air to remove any remaining residue.
=== Step 4: Installing the New Brake Pads: A Step-by-Step Guide ===
With the calipers inspected and cleaned, it is now time to install the new brake pads. Start by applying a thin layer of high-temperature brake lubricant to the back of each pad. This will help reduce noise and prevent the pads from sticking to the caliper bracket.
Place the new brake pads into the caliper bracket, ensuring they are correctly aligned with the rotor. If your brake pads have retaining clips or pins, carefully reinstall them in their original positions. Double-check that the pads are securely seated and move freely within the bracket.
Next, carefully slide the caliper back over the rotor, aligning the bolt holes with the caliper bracket. Insert the caliper bolts and tighten them to the manufacturer’s specified torque using a torque wrench. Be cautious not to overtighten the bolts, as this may damage the caliper or other components.
=== Step 5: Testing and Final Checks: Ensuring Proper Brake Functionality ===
After installing the new brake pads, it is crucial to test the braking system to ensure proper functionality and safety. Start by pumping the brake pedal a few times to reposition the caliper pistons and establish initial contact with the rotor. This will help eliminate any excessive pedal travel or sponginess.
Once the brake pedal feels firm, start the vehicle and perform a few low-speed stops to bed the new brake pads into the rotor surface. Listen for any abnormal noises or vibrations during braking, as these may indicate improper installation or other issues.
Finally, conduct a visual inspection to ensure all components are securely in place, with no signs of leaks or damage. Reinstall the wheels, tightening the lug nuts in a star pattern to ensure even pressure distribution. Lower the vehicle from the jack stands and perform a final torque check on the lug nuts.
Congratulations! You have successfully completed the DIY brake replacement for your Infiniti G35. By following these step-by-step instructions and exercising caution throughout the process, you have saved both time and money while maintaining optimal braking performance. Remember to refer to your vehicle’s service manual for any model-specific instructions or specifications. Stay safe and enjoy the peace of mind of a well-maintained braking system.
