The FD RX-7 is known for its lightweight design and exceptional handling. However, to enhance its performance further, upgrading to a big brake kit can make a significant difference. This article will guide you through the steps to install a big brake kit on your FD RX-7.
Understanding the Benefits of a Big Brake Kit
A big brake kit offers numerous advantages over the stock brake system, including:
- Improved Stopping Power: Larger rotors and calipers provide better braking performance.
- Heat Dissipation: Bigger brakes can handle heat better, reducing brake fade during intense driving.
- Enhanced Modulation: Improved pedal feel allows for better control during braking.
- Increased Aesthetic Appeal: Upgraded brakes can enhance the visual aspect of your wheel setup.
Choosing the Right Big Brake Kit
When selecting a big brake kit for your FD RX-7, consider the following factors:
- Compatibility: Ensure the kit is specifically designed for the FD RX-7.
- Performance Goals: Determine whether you need the kit for street use, track days, or drifting.
- Budget: Big brake kits can vary significantly in price; set a budget before shopping.
- Brand Reputation: Research brands known for quality and reliability in brake systems.
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- Tools:
- Jack and jack stands
- Socket set
- Torque wrench
- Brake cleaner
- Brake fluid
- Bleeder kit
- Materials:
- Big brake kit (calipers, rotors, pads)
- Brake lines (if included)
- New hardware (if required)
Step-by-Step Installation Guide
1. Prepare Your Vehicle
Start by parking your FD RX-7 on a level surface and engaging the parking brake. Loosen the lug nuts on the front wheels before lifting the car with a jack. Secure it with jack stands for safety.
2. Remove the Stock Brake Components
Begin by removing the front wheels. Next, detach the brake caliper by unscrewing the bolts securing it to the bracket. Hang the caliper using a wire or bungee cord to avoid straining the brake line. Remove the stock rotor by taking off the retaining screws if present.
3. Install the Big Brake Kit
Position the new rotor onto the hub and secure it with the retaining screws. Next, install the new caliper over the rotor, ensuring it aligns with the mounting bracket. Use the provided hardware to secure the caliper and torque it to the manufacturer’s specifications.
4. Install New Brake Lines
If your big brake kit includes new brake lines, replace the stock lines with the new ones. Ensure all connections are tight and free of leaks.
5. Repeat for the Rear Brakes
Follow the same procedure for the rear brakes, ensuring that you replace the rotors, calipers, and lines as needed.
6. Bleed the Brake System
After installing the big brake kit, it’s crucial to bleed the brake system to remove any air. Start with the wheel furthest from the master cylinder and work your way to the closest. Use a bleeder kit and follow the manufacturer’s instructions.
7. Test the Brakes
Before taking your FD RX-7 on the road, pump the brake pedal several times to build pressure. Check for any leaks and ensure the pedal feels firm. Conduct a short test drive to ensure the brakes are functioning correctly.
Maintenance Tips for Your Big Brake Kit
To keep your big brake kit in optimal condition, follow these maintenance tips:
- Regular Inspections: Check brake pads and rotors for wear periodically.
- Brake Fluid Changes: Change the brake fluid every 1-2 years to maintain performance.
- Keep It Clean: Clean the brake components to prevent dust buildup.
- Monitor Brake Temperature: If you track your vehicle, consider using temperature-sensitive paint to monitor heat levels.
Conclusion
Installing a big brake kit on your FD RX-7 can significantly improve handling and performance. By following this guide, you can enhance your vehicle’s braking capabilities and enjoy a more responsive driving experience. Always prioritize safety and ensure that your upgrades are installed correctly.
