For automotive enthusiasts and DIY technicians, upgrading to stainless steel (SS) brake lines is a popular performance enhancement that can significantly improve braking efficiency and pedal feel. Goodridge, a leader in the production of braided stainless steel brake lines, offers kits tailored for a range of vehicles, including Honda Civic models from 2016 to 2021. These kits replace factory rubber lines, which are prone to expansion under heat, with durable stainless steel braided lines that resist such issues.
The installation of these lines requires precision, attention to detail, and adherence to manufacturer specifications to ensure safety and performance. This article provides a detailed breakdown of the installation process based on the technical documentation and guidelines provided by J2 Precision and Unity Performance. Emphasis is placed on correct routing, torque specifications, and bleeding procedures to ensure the system functions as intended.
Overview of Goodridge Stainless Steel Brake Lines
Goodridge stainless steel brake lines are engineered to replace standard rubber brake lines in various automotive applications. These lines are constructed with a braided stainless steel outer layer that surrounds a flexible inner tube, which carries the brake fluid. The braiding serves as a reinforcement that prevents the line from expanding under pressure or heat, which can cause a spongy brake pedal. This design ensures consistent pedal feel and reduces the risk of brake fluid boiling or line failure during aggressive driving.
The documentation highlights that these lines are particularly beneficial for vehicles subjected to spirited driving or track use. For example, the documentation notes that the 2017–2021 Honda Civic Type R FK8 models, as well as the base models from 2016 to 2021, are compatible with Goodridge SS brake lines. These upgrades are recommended for drivers who seek improved braking performance and a more responsive brake pedal.
Goodridge has been a pioneer in the development of stainless steel brake lines for motorsport use and has since established a reputation for quality and reliability in the consumer market. The documentation includes testimonials from users who have tested these lines on their vehicles, including a 2017 Honda Civic Si sedan used for both spirited driving and occasional track use.
Key Installation Steps and Technical Requirements
The installation process for Goodridge stainless steel brake lines involves several critical steps, including removing the original rubber lines, routing the new lines, securing them with the appropriate hardware, and bleeding the brake system. Each step must be performed with precision to ensure the system functions correctly and safely.
Preparation and Safety Measures
Before beginning the installation, it is essential to gather the necessary tools and materials, including a new pint of Dot 4 brake fluid, safety glasses, jack stands, and appropriate wrenches. The documentation emphasizes the importance of wearing safety glasses when handling brake fluid, as it can damage paint and skin. Additionally, if the vehicle is jacked up, it must be supported with proper jack stands before working underneath it.
The documentation also advises that any operation not fully understood should be left to a professional to avoid the risk of brake failure. This is particularly important given the critical nature of the braking system. Users unfamiliar with bleeding procedures or torque specifications are encouraged to seek assistance from a qualified technician.
Removal of Factory Lines
The first step in the installation process is to note how the factory lines are routed and secured. The replacement lines should follow the same path, with the exception of minor adjustments in the rear line. The documentation specifies that the new lines must be routed through the same tie wraps and supports as the original lines to prevent interference with suspension components or other moving parts.
When removing the factory lines, users should use a tubing wrench to avoid damaging the steel lines. The rear line assembly is loosened at the 90-degree fitting connected to the master cylinder. The line must be gently bent to follow the curvature of the chassis without kinking. The documentation includes instructions to ensure the line points toward the rear differential and aligns with the wiring loom for proper clearance.
Installation of New Lines
Once the factory lines have been removed, the new Goodridge stainless steel lines can be installed. The rear line is attached to the caliper using the short banjo bolt provided in the kit. Brass sealing washers are placed on both sides of the banjo bolt to create a secure and leak-proof connection. The bolt is tightened to a torque specification of 14 ft. lbs.
The rear line is then routed through the newly installed tie wraps and secured to the wiring loom. A regular tie wrap is used to fasten the line in place. The line is also connected to the slightly bent steel line at the chassis, using a 10mm line wrench and a 17mm wrench to prevent twisting. This connection is also tightened to 14 ft. lbs.
For the front lines, two banjos are installed on the front calipers using four brass sealing washers and two long banjo bolts. The washers are positioned between the banjo and the caliper, as well as between the banjo and the bolt. The banjos should be aligned so that their threaded ends point toward the center of the vehicle. The bolts are tightened to 14 ft. lbs.
The front lines are then routed to the master cylinder, following the same path as the original hose. A tee fitting is secured in the same location as the original using the original bolt. The shortest line is connected to the master cylinder using a long banjo bolt and two brass sealing washers. The connection is tightened to 14 ft. lbs.
Final Adjustments and Securing
After the lines are installed, they must be loosely attached to the wheels and secured in the provided routing. The documentation specifies that the tie wraps should not be pulled tight but should hold the line and wiring loom in the correct location. The lines must also be routed without twisting and secured to prevent rubbing against other components.
Once all connections are made, the junctions should be cleaned, and the brake system should be bled. Users are instructed to push firmly on the brake pedal while a helper checks for leaks at all junctions. Any leaks must be repaired immediately before operating the vehicle.
After bleeding, the brake pedal should be held firmly for 60 seconds. If the pedal sinks, it indicates a leak. The documentation emphasizes that any such issue must be addressed before proceeding.
Finally, the vehicle should be reassembled, and a slow test drive should be performed to check the brake function at low speeds. The lines should be inspected for rubbing or pulling, and any issues must be corrected before normal use.
Bleeding Procedures and Post-Installation Checks
Bleeding the brake system is a crucial step in the installation process. The documentation specifies that a new pint of Dot 4 brake fluid must be used and that the original fluid should not be reused. The old fluid must be disposed of properly, as it can damage paint and other surfaces.
The bleeding process involves opening the bleeder valves at the calipers and allowing the old fluid to drain. Fresh Dot 4 fluid is then introduced into the master cylinder, and the system is bled until all air bubbles are removed. The documentation provides instructions for pushing firmly on the brake pedal during this process, with a helper monitoring for leaks.
After bleeding, the brake pedal should feel firm and should not sink when pressure is held. This is an indication that the system is free of leaks and that the lines are properly secured. Any softness or sinking of the pedal suggests a leak that must be repaired before the vehicle is operated.
The documentation also includes a reminder to clean all junctions after installation and before bleeding the system. Dirt and debris can interfere with the performance of the braking system and should be removed to ensure optimal function.
Conclusion
Goodridge stainless steel brake lines offer a reliable and effective upgrade for drivers seeking improved braking performance and a more consistent pedal feel. The installation process, while technically demanding, is well-documented and provides detailed instructions for each step. Users are encouraged to follow the torque specifications, routing guidelines, and bleeding procedures to ensure the system functions correctly and safely.
Given the critical nature of the braking system, the documentation emphasizes the importance of proper installation and the need for professional assistance if any step is unclear. By adhering to the manufacturer's recommendations and using the correct tools and materials, users can ensure that their Goodridge stainless steel brake lines perform as intended and provide long-term durability and performance.
