While the front half of this book written by Larry Carley is well-done, it only covers brake basics and original-equipment information. As a racer, I use the second half of the book, written and photigraphed by Mike Mavrigian, which covers racing brake systems in great detail, for every type of racing use. The race section is extremely well done and provides useful information for anyone setting up a brake system on a drag, oval or road race vehicle. The book should be called "Racing Brake Systems," as I've found this to the the information that really helps me. Good for both the beginning racer as well as the seasoned racer. Plenty of great tips, and lots of things I've never thought of before. Very useful.
