The Infiniti G37 is known for its performance and luxury, but to unlock its full potential on the track or the street, an upgrade to the braking system is essential. This guide will cover the installation of Brembo 4-piston calipers and slotted rotors, a combination that enhances stopping power and improves overall driving dynamics.
Why Upgrade Your Brakes?
Upgrading your brakes is crucial for several reasons:
- Improved Stopping Power: Enhanced calipers and rotors provide better braking performance.
- Heat Dissipation: Slotted rotors help in cooling, reducing brake fade during intense driving.
- Better Pedal Feel: Upgraded calipers offer a firmer and more responsive pedal feel.
- Increased Safety: Improved braking reduces stopping distances, enhancing safety.
Components Needed for the Upgrade
To successfully upgrade your Infiniti G37’s braking system, you will need the following components:
- Brembo 4-piston calipers
- Slotted rotors (front and rear)
- High-performance brake pads
- Brake fluid (DOT 4 recommended)
- Brake lines (optional, for better performance)
- Installation tools (wrenches, sockets, etc.)
Installation Process
Step 1: Preparation
Before starting the installation, ensure you have all the necessary tools and components ready. Park the vehicle on a flat surface and engage the parking brake.
Step 2: Remove the Wheels
Using a lug wrench, loosen the lug nuts on the front wheels. Lift the vehicle using a jack and secure it with jack stands. Remove the wheels to access the brake components.
Step 3: Remove the Old Brake Components
Detach the caliper from the rotor by removing the bolts that secure it. Carefully slide the caliper off the rotor and hang it using a bungee cord or wire to avoid stress on the brake line. Remove the old rotor by unscrewing any retaining screws.
Step 4: Install the Slotted Rotors
Position the new slotted rotor onto the hub. Ensure it is seated properly and secure it with the retaining screws. Repeat this process for the rear rotors if applicable.
Step 5: Install Brembo 4-Piston Calipers
Carefully position the Brembo caliper over the new rotor. Align it with the mounting bracket and secure it using the provided bolts. Make sure to torque the bolts to the manufacturer’s specifications.
Step 6: Install New Brake Pads
Insert the high-performance brake pads into the caliper. Ensure they are seated correctly and are free from any debris.
Step 7: Reinstall the Wheels
Reattach the wheels to the vehicle, hand-tightening the lug nuts initially. Lower the vehicle from the jack stands and then tighten the lug nuts to the specified torque.
Step 8: Bleed the Brakes
To ensure there are no air bubbles in the brake lines, bleed the brakes using the appropriate method. This typically involves having a helper pump the brake pedal while you open and close the bleeder valve on each caliper.
Cost Breakdown
The estimated cost for this upgrade can vary based on the components chosen. Here is a basic breakdown:
- Brembo 4-piston calipers: $1,200
- Slotted rotors: $600
- High-performance brake pads: $200
- Brake fluid: $30
- Miscellaneous (tools, lines): $100
Final Thoughts
Upgrading to Brembo 4-piston calipers and slotted rotors is a worthwhile investment for any Infiniti G37 owner looking to enhance their vehicle’s braking performance. With improved stopping power and safety, this upgrade will make a noticeable difference in both daily driving and spirited track days.
