Using your AS3 Venhill front brake line hose is easy. First, make sure your vehicle is turned off and on a stable surface. Locate the old brake line on your Honda model (it fits 1995 - 2008 CR 125, 1995 - 2008 CR 250, 1995 - 2001 CR 500, 2004 - 2008 CRF 250 R, and 2002 - 2008 CRF 450 R). Remove the old line carefully. Then, install the new AS3 Venhill brake line. Use the included copper washers and adjust the banjo angle using the stainless - steel swivel unions for a perfect fit. When it comes to maintenance, check the brake line regularly for any signs of wear or damage. If you notice any leaks or cracks, replace the line immediately. Keep the line clean and free from dirt and debris. Also, remember that this product is DOT and TUV approved, so it meets high - quality standards. It comes with a 12 - month warranty from a UK company, so if you have any issues, don't hesitate to contact them.
