The Lexus IS has long been celebrated for its blend of luxury and performance. However, to truly elevate the driving experience, especially on the street and track, upgrading the braking system can make a significant difference. One of the most effective upgrades is the installation of a big brake kit. This article will guide you through the benefits of a big brake kit and provide a step-by-step installation process.
Benefits of a Big Brake Kit
Upgrading to a big brake kit offers several advantages over the stock braking system. Here are some of the key benefits:
- Improved Stopping Power: Larger brake calipers and rotors provide more surface area, resulting in better braking performance.
- Heat Dissipation: Bigger brakes can dissipate heat more effectively, reducing brake fade during extended use.
- Enhanced Pedal Feel: A big brake kit often improves the responsiveness of the brake pedal, providing better feedback to the driver.
- Custom Aesthetics: Many big brake kits come in various colors and designs, allowing for a personalized look.
Choosing the Right Big Brake Kit
When selecting a big brake kit for your Lexus IS, consider the following factors:
- Vehicle Model: Ensure the kit is specifically designed for your Lexus IS model and year.
- Driving Style: Choose a kit that matches your driving style, whether it’s for street use, track days, or both.
- Budget: Big brake kits can vary significantly in price; set a budget that balances quality with cost.
- Brand Reputation: Opt for reputable brands known for their performance and reliability.
Installation Process
Installing a big brake kit on your Lexus IS can be a rewarding DIY project. Here’s a step-by-step guide to help you through the installation process.
Tools and Materials Needed
- Big brake kit (calipers, rotors, pads)
- Jack and jack stands
- Socket set
- Torque wrench
- Brake cleaner
- Brake fluid
- Rags
- Optional: Brake line wrench
Step 1: Prepare the Vehicle
Begin by parking your Lexus IS on a flat surface. Engage the parking brake and loosen the lug nuts on the front wheels. Then, using a jack, lift the front of the vehicle and secure it with jack stands.
Step 2: Remove the Stock Brakes
Once the vehicle is securely elevated, remove the front wheels. Next, disconnect the brake line from the stock caliper using a brake line wrench. Be prepared for some brake fluid to leak out, so have rags handy. Remove the caliper bolts and take off the stock caliper. Then, remove the stock rotors.
Step 3: Install the New Rotors
Clean the hub surface with brake cleaner to ensure proper contact. Install the new rotors onto the hub, ensuring they are seated correctly. If the new rotors have a directional design, make sure they are oriented properly.
Step 4: Install the New Calipers and Pads
Next, install the new calipers onto the new rotors. Secure them using the provided bolts, following the manufacturer’s torque specifications. Then, insert the new brake pads into the calipers, ensuring they are positioned correctly.
Step 5: Reconnect the Brake Lines
Reconnect the brake lines to the new calipers. Make sure to use new copper washers if provided with the kit to prevent leaks. Tighten the connections securely, but avoid over-tightening.
Step 6: Bleed the Brakes
After everything is installed, it’s crucial to bleed the brakes to remove any air from the system. Begin at the caliper furthest from the master cylinder and work your way to the closest. Use a brake bleeder kit or have a helper pump the brake pedal while you open and close the bleeder valve.
Step 7: Reassemble and Test
Once the brakes are bled, reattach the wheels and lower the vehicle. Tighten the lug nuts to the manufacturer’s specifications. Before driving, pump the brake pedal a few times to ensure proper engagement. Finally, take the car for a test drive to evaluate the new braking performance.
Conclusion
Installing a big brake kit on your Lexus IS can significantly enhance both street and track performance. With improved stopping power, better heat dissipation, and an overall upgraded driving experience, this modification is well worth considering. By following the steps outlined in this article, you can successfully install a big brake kit and enjoy the benefits it brings to your driving experience.
