The Mazda RX-7 is a legendary sports car known for its lightweight design and rotary engine performance. When tuning your RX-7 to exceed 350 horsepower, upgrading the braking system becomes essential for safety and performance. Installing a big brake kit is one of the most effective ways to enhance braking performance, ensuring that your vehicle can handle the increased power efficiently.
Understanding the Need for a Big Brake Kit
As horsepower increases, so does the demand on the braking system. The stock brakes on the RX-7 may struggle to provide adequate stopping power when faced with higher speeds and aggressive driving. A big brake kit addresses this issue by offering larger rotors and calipers, which improve heat dissipation and overall braking performance.
Benefits of Installing a Big Brake Kit
- Improved Stopping Power: Larger rotors and calipers provide better leverage and braking force.
- Heat Management: Bigger brakes dissipate heat more effectively, reducing brake fade during heavy use.
- Better Pedal Feel: Upgraded calipers often offer a firmer pedal response, enhancing driver confidence.
- Increased Performance: Enhanced braking allows for later braking points, improving lap times on the track.
Choosing the Right Big Brake Kit
When selecting a big brake kit for your Mazda RX-7, consider the following factors:
- Compatibility: Ensure the kit is specifically designed for the RX-7 model and year.
- Material: Look for high-quality materials such as aluminum calipers and slotted or drilled rotors.
- Brand Reputation: Research brands that are known for their performance parts and customer satisfaction.
- Cost: Balance your budget with the features and quality of the brake kit.
Installation Process
Installing a big brake kit can be a rewarding project. Here’s a step-by-step guide to help you through the process:
Tools and Materials Needed
- Big brake kit components
- Jack and jack stands
- Socket set
- Torque wrench
- Brake cleaner
- Brake fluid
- Rags for cleanup
Step-by-Step Installation
- Prepare the Vehicle: Park on a level surface, engage the parking brake, and lift the car using a jack.
- Remove the Wheels: Take off the wheel nuts and remove the wheels to access the brake components.
- Remove Stock Brakes: Disconnect the brake line and remove the caliper and rotor from the hub.
- Install New Rotors: Place the new rotor onto the hub and secure it properly.
- Mount New Calipers: Attach the new calipers to the mounting points and connect the brake lines.
- Bleed the Brakes: Use a brake bleeder kit to remove air from the brake lines, ensuring a firm pedal feel.
- Reinstall Wheels: Place the wheels back on and tighten the nuts to the manufacturer’s specifications.
- Test Drive: Carefully test the brakes in a safe environment to ensure everything is functioning correctly.
Maintenance Tips for Big Brake Kits
To ensure your big brake kit performs optimally, follow these maintenance tips:
- Regular Inspections: Check brake pads and rotors for wear regularly.
- Keep Components Clean: Clean brake components to prevent dirt and debris buildup.
- Monitor Brake Fluid: Regularly check and replace brake fluid as needed.
- Watch for Noise: Listen for any unusual noises that may indicate issues.
Conclusion
Upgrading to a big brake kit on your Mazda RX-7 is a crucial step when pushing the limits of performance beyond 350 horsepower. With improved stopping power, heat management, and overall driving confidence, you can enjoy your RX-7 to its fullest potential. Follow the installation guide and maintenance tips to ensure your braking system remains in top condition, enhancing both safety and performance on the road or track.
