i don't have my manual with me...are we supposed to be changing the brake fluid on a reg. basis? (2 years?). reason i'm asking is a friend showed me in his volkswagen manual "you need to change the fluid every 2 years". to tell you the truth i have NEVER changed brake fluids in any of my vehicles, unless they were having the brakes overhauled. am i a MORON?:dontknow:
