Using these Faction Fab brake lines is straightforward. First, make sure your vehicle is parked on a flat surface and the engine is off. Refer to your vehicle's manual to locate the front brake lines. Remove the old factory rubber lines carefully, taking note of how they are attached. Then, install the new stainless - steel brake lines, using the included hardware. Make sure all fittings are tightened properly. After installation, bleed the brakes to remove any air from the system. This will ensure optimal braking performance. As for maintenance, regularly check the brake lines for any signs of damage or wear, such as cuts or leaks. If you notice any issues, replace the lines immediately. Keep the lines clean by wiping them down occasionally with a soft cloth. Also, during cold weather, pay extra attention as extreme temperatures can affect the performance of the braking system.
