Use the appropriate bleeder wrench to gently remove this screw and close it back (you removed the bleeder screw with a bleeder wrench to make sure it was openable, now place a hose on the outlet of the bleeder screw and direct the other end to a bucket to reduce dirt.
Fill this bucket with new brake fluid to serve as reverse pressure. If you don’t have a brake bleeder tool or brake bleeder kit, you can have your friend pump the brakes, and as the brake pumps, you can then gently open the bleeder screw again, but this time tell your friend to hold the brake down and cover your face or bob because there would be a squirt of brake fluid.
Before your friend releases this brake again, make sure you tighten the bleeder screw with a bleeder wrench. Once this is done, tell your friend to release the brakes and repeat this process until no more air bubbles come out with this squirt of brake fluid.
