How Often Should Brake Fluid Be Flushed? Thanks.
Man I am a slacker.......25,000+ miles and just put a set of front pads on mine. Same fluid since 2006 I'll put it on my list for when I replace the front againThe service manual has a replace of the fluid every 10K miles, I've done mine once in 4 years and 13K miles. Probably do mine next service at 15K since its been a while again, besides Oscar is making me feel like a slacker!
See maybe I'm not a slacker, maybe I already knew this and thats why I haven't changed the brake fluid........Naw....I'm a slacker Thanks for the info AndrewDOT 3, 4 and 5.1 are all Glycol based. The Gycol traps moisture and should be changed out ever 2-3 years at most. Or if it changing to an off color rather than clear, it should be changed.
DOT 5 (used in Big dogs) is a silicone based fluid and will not draw in moisture like the other fluids. So, as long as you know the system has not been contaminated with outside water or dirt, there is no need to change it. Studies have shown that after many years of use, it still gives the same hydraulic and boiling limits as it would new. Because it doesn't trap moisture like the others, there is no concern about corrosion in the braking system.
I believe DOT 5 is also used a lot in military and in Northern parts of the world such as Alaska, Russia, Canada....
Soooo, change it if you feel you need to, otherwise if it's clean, don't worry about.
+1If water gets in your brake system, it will not mix with your fluid but will sit in the bottom of your brake cylinder.(water is heavier than fluid)
Say we go past those limits and we find a pauly drop. What happens next after many years listening to your science. Someone leaves a lid open and oh look, no water on the bottom. That sounds like what you looked up and not thought thru how simple that science is.Studies have shown that after many years of use, it still gives the same hydraulic and boiling limits as it would new.
