In case anyone was interested, I found a pretty informative document from PBR about brake systems in general. While this is not the most technical document, it does cover the basics as well as some brake system diagnosis tips. http://www.pbr.com.au/pbr/rwp.nsf/33e0cc226acce9824a256421000873c0/f6721 539d6db704cca256894000b7fa6/$FILE/ATT2616P/PB523-Braking_Guide_AW.pdf Taka
