How do you bleed the brakes on 2130?

To bleed the brakes on a 2130, start by ensuring the vehicle is on a level surface and the wheels are securely chocked. Locate the brake bleeder valve on each wheel cylinder, then use a wrench to open the valve slightly. Have an assistant pump the brake pedal several times and hold it down while you open the bleeder valve to release air and old fluid, then close the valve before the pedal is released. Repeat this process until you see a steady stream of fluid without bubbles, starting from the wheel farthest from the master cylinder and moving closer.
