Using these brake lines is easy. First, make sure your motorcycle is turned off and on a stable surface. Remove the old brake lines carefully, then install the new AS3 Venhill brake lines. Use the stainless steel swivel unions to adjust the banjo angle so it aligns perfectly with the caliper and master cylinder. Tighten the connections properly. When it comes to maintenance, regularly check the lines for any signs of wear, like cuts or leaks. Keep the lines clean and away from sharp objects. If you notice any issues, contact the UK - based company within the 12 - month warranty period. Remember, custom colors or orders are available if you have special requirements.
