How can I effectively use WD40 on my bike brakes to improve their performance?

To effectively use WD40 on your bike brakes, start by cleaning the brake components with a degreaser to remove any dirt or grime. Then, apply a small amount of WD40 to the brake pivots and springs to lubricate them. Be sure to wipe off any excess WD40 to prevent it from attracting dirt. Test your brakes to ensure they are functioning properly before riding.
