Just pulling the master cylinder to replace all the seals and the leaky grommets.
The Rave says anything "upstream" of the modulator requires the Testbook computer to properly bleed...
Before I break it down I wanted to make sure I can just do a standard manual bleed of the brakes once the Cylinder goes back on and not require the computer.

 

You can do a total bleed without using the test book.
Make sure to have 3 quarts of DOT 4 and bleed each wheel till perfectly clear.
