Expect to flush out the old fluid soon as the stuff in the master cylinder is brown. Lots of how to videos on youtube, and my brother will help. He's done this before on other cars. His question is what type of tool do we need to open up the bleeder valves. Regular open end wrench or something more specialized? We intend to do this on the ground. We have ramps but should we use them? Any and all hints welcome. Thanks in advance.
