I use the Motive Bleeder. One man operation. No compressor needed. Nobody pushing on the brake pedal. It costs about $85.00 but if you work on your own cars, it is worth every penny. Lots of YouTube videos on it. Takes longer to get the car on jack stands and taking off the wheels than it does to bleed/flush the brake fluid.
Note: it does not flush out the ABS. What fluid is in there will remain.
Please take note of this!
You will need to either find someone or rent or buy a tool to open the ABS module via the ECU. A GM Tech II or one of the high-end OBDII devices can do this. Otherwise you will not be getting a full flush if that is your goal.
You can check the Motive website, or Amazon also has them listed as well.
