Even though this book is used as a teaching text for hydraulics in marine engineering, the principles are the same. Get a copy of this book, they are still in print, you will be amazed at the information compiled. And it has clear and very concise descriptions about the principles of hydraulics. No doubt brakes can be complicated with such items as proportioning meters and valves etc. But this book explains in detail about hydraulics, a great reference book to own. It wont tell you how to solve a problem with your particular braking system, but it sure does illustrate the complexity's of hydraulic principles !
