Curious, why so many people stress the importance of motorcycle brake fluid change intervals (annually seems to be the most common) and yet, of all the car forums I've been a member of for years and years, of all the shade tree mechanics I've known and worked with, of all the used cars I've helped people buy/fix, no one ever speaks about brake fluid change intervals on them. Why do people stress the importance on a motorcycle and seemingly (with life experience to validate this claim) ignore the brake fluid in their car/truck? Is it because we're on 2 wheels instead of 4 so brakes are a little more important? I don't understand the logic. With a speed bleeder (pneumatic or pump type) the process on a car takes 30 minutes or less. Why are so many people ignoring that and yet, I've always been preached to about motorcycle brake fluid being an annual or bi-annual necessity?
