In order to bleed brakes by yourself, you will need a pressure bleeder and a brake bleeder wrench. Start with the bleeder valve that isn’t close to the master cylinder and open the bleeder screw gently.

Remember to be very gentle opening the bleeder screw, do this with all the bleeder valves. However, make sure that at the time of bleeding these valves, the brake fluid doesn’t fall below one quarter as this could lead to more air being sucked in.

Once you are done bleeding this brake with your vacuum brake bleeder, you can put back your tires and check to see if the master cylinder needs to be topped with more brake fluid. If it needs topping, make sure to add more brake fluid and pump the brakes to make sure it is better now.

If there isn’t enough brake fluid, then the brake pedal will touch the floor when the engine is running, but if it actually works, you should experience just a little bit more stiffness when you pump the brakes.
