The NA Miata is a beloved sports car known for its lightweight design and agile handling. However, to enhance its performance on the track or the street, upgrading the braking system is essential. This article will guide you through a DIY performance brake upgrade for your NA Miata, focusing on installing slotted rotors and high-performance brake pads, all for around $700.
Why Upgrade Your Brakes?
Braking is one of the most critical aspects of any performance vehicle. Upgrading your brakes can lead to:
- Improved stopping power
- Better heat dissipation
- Less brake fade during aggressive driving
- Enhanced pedal feel and response
Parts Needed for the Upgrade
Before starting the upgrade, gather the following parts:
- Slotted rotors (front and rear)
- High-performance brake pads (front and rear)
- Brake fluid (DOT 4 recommended)
- Brake cleaner
- Brake grease
- Basic hand tools (socket set, wrenches, etc.)
- Jack and jack stands
- Torque wrench
Step-by-Step Installation Guide
1. Prepare Your Workspace
Ensure you have a clean and safe workspace. Park your NA Miata on a flat surface and engage the parking brake. Gather all your tools and parts before starting the installation.
2. Lift the Vehicle
Using a jack, lift the front of the vehicle and secure it with jack stands. Repeat this process for the rear of the car. Always ensure the vehicle is stable before working underneath it.
3. Remove the Wheels
Use a socket wrench to remove the lug nuts and take off the wheels. This will give you access to the brake components.
4. Remove Old Brake Components
Start by removing the caliper bolts. Carefully slide the caliper off the rotor, and support it with a bungee cord or rope to avoid straining the brake line. Next, remove the old brake pads and rotor.
5. Install New Slotted Rotors
Clean the new slotted rotors with brake cleaner to remove any protective oil. Install the rotor onto the hub, ensuring it is seated properly. Secure it with the appropriate hardware.
6. Install New Brake Pads
Apply brake grease to the backing of the new high-performance brake pads. Insert the pads into the caliper bracket, making sure they fit snugly. Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
7. Repeat for All Wheels
Repeat steps 4 to 6 for the rear brakes. Ensure that all components are installed correctly and securely.
8. Bleed the Brakes
To ensure no air is trapped in the brake lines, bleed the brakes. Start from the wheel farthest from the master cylinder and work your way forward. Use a brake bleeder kit or have a friend pump the brake pedal while you open and close the bleeder valve.
9. Reinstall the Wheels
Once the brakes are bled, reinstall the wheels and hand-tighten the lug nuts. Lower the vehicle back to the ground and torque the lug nuts to the specified settings.
10. Test Drive
Before hitting the road, pump the brake pedal a few times to ensure proper brake engagement. Take your NA Miata for a short test drive to ensure everything is functioning correctly. Pay attention to the brake feel and listen for any unusual noises.
Cost Breakdown
Here’s a rough estimate of the costs involved in this upgrade:
- Slotted rotors: $300
- High-performance brake pads: $250
- Brake fluid: $20
- Miscellaneous supplies (cleaner, grease, etc.): $30
Conclusion
Upgrading the brakes on your NA Miata with slotted rotors and high-performance pads is a fantastic way to enhance your driving experience. With a budget of around $700, you can significantly improve your vehicle’s stopping power and overall performance. Remember to follow each step carefully, and enjoy the thrill of driving your upgraded Miata!
