The Mk8 Golf R is a powerhouse of performance, but to truly unleash its potential on the track, upgrading the brake system is essential. One of the best upgrades you can make is installing a 6-piston big brake kit (BBK). This article will guide you through the benefits and the installation process of a 6-piston BBK for track days.
Why Upgrade to a 6-Piston BBK?
Upgrading to a 6-piston BBK provides numerous advantages over the factory brake system. Here are some key benefits:
- Improved Stopping Power: The additional pistons increase clamping force, allowing for quicker and more effective stops.
- Better Heat Dissipation: Larger rotors and calipers help manage heat better, reducing brake fade during intense track sessions.
- Enhanced Modulation: A 6-piston setup offers better pedal feel and control, making it easier to modulate braking force.
- Increased Durability: High-performance components are designed to withstand the rigors of track driving.
Choosing the Right 6-Piston BBK
When selecting a 6-piston BBK for your Mk8 Golf R, consider the following factors:
- Brand Reputation: Choose reputable brands known for quality and performance.
- Compatibility: Ensure the kit is specifically designed for the Mk8 Golf R.
- Rotor Size: Opt for larger rotors for better heat management.
- Pad Material: Select pads that suit your driving style, whether for street or track use.
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- 6-piston BBK kit
- Socket set
- Torque wrench
- Brake cleaner
- Brake fluid
- Jack and jack stands
- Wheel chocks
- Safety glasses and gloves
Installation Process
Step 1: Prepare the Vehicle
Start by ensuring your vehicle is on a flat surface. Use wheel chocks to prevent movement. Loosen the lug nuts on the front wheels before lifting the car with a jack.
Step 2: Remove the Stock Brakes
Once the car is elevated, remove the front wheels. Disconnect the brake line from the stock caliper and remove the caliper from the bracket. Next, take off the stock rotor.
Step 3: Install the 6-Piston Calipers
Position the new 6-piston caliper onto the bracket and secure it using the supplied hardware. Ensure it is torqued to the manufacturer’s specifications.
Step 4: Attach the New Rotors
Place the new rotor onto the hub and ensure it is seated properly. Reinstall the caliper over the rotor, making sure the brake pads are in place.
Step 5: Connect Brake Lines
Reconnect the brake lines to the new caliper. Be cautious to avoid any leaks. Use brake cleaner to clean any spilled fluid.
Step 6: Bleed the Brakes
To ensure proper brake function, bleed the brake system to remove any air. Start from the caliper furthest from the master cylinder and work your way closer.
Step 7: Reinstall the Wheels
Once the brakes are bled, reinstall the front wheels. Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications.
Testing the New Brake System
After installation, it’s crucial to test the new brake system. Follow these steps:
- Perform a low-speed brake test to check for any unusual noises or issues.
- Gradually increase speed and test braking performance.
- Ensure the pedal feel is firm and responsive.
Conclusion
Upgrading to a 6-piston BBK on your Mk8 Golf R can significantly enhance your track performance. With improved stopping power, better heat dissipation, and increased durability, this upgrade is well worth the investment for serious track enthusiasts. Follow this guide for a successful installation and enjoy the thrill of enhanced braking on your next track day!
