The only mention of brake fluid in the maintenance manuals is simply to check the level. However, looking through the manuals for my Nissan and my Kia, neither has any requirement listed to ever change the brake fluid under any circumstances. We all know Porsche and Mercedes recommend changing brake fluid every two years, as do most motorcycle manufacturers. However, there is little agreement as far as changing/flushing brake fluid. Pretty much all agree on changing engine oil, some list transmission & differential oil as optional depending on operating conditions, same for coolant intervals, etc. It's not a bad idea, to be sure, and for a car that sees track duty, it should be considered a mandatory maintenance item.īut is it really necessary for a street only car?Ĭonsider this: Every manufacturer has maintenance schedules for the vehicles they make, ALL have engine oil & filter changes required, trans oil changes, diff oil changes, coolant changes, and transfer case oil changes. I doubt very seriously changing the brake fluid is as critical as some make it out to be. Probably s/b changed every 6 months in this heat Wipers? Give me a break! Whenever I do not like how they wipe, LOL. or 40K whichever comes 1st but admitted if it was his car, he’d wait till 40K miles. PDK fluid? IDK I asked a Porsche mechanic & he reiterated the official position of 4 yrs. (Porsche mechanic also said he thinks that is OK) I’m going to do mine 30K miles Which will be > 4 years. A Garage queen’s air filters are NOT getting dirty sitting in the garage! (Yes some want to analyze their old oil & change it every monthĮngine air filters s/b mileage & not time.

Especially the ones that have time & mileage, whichever comes 1st.

I think a lot of scheduled maintenance items are questionable. I was wondering about literally same moisture content (0%) 2 years as just after changing the fluid.Įverything I can find in Google searches talks about moisture. Maybe some would be able to change it every 3 years if not living in a humid climate I realize that if everyone tested their brake fluid 2 years, the vast majority would have moisture.

My question has nothing to do with warranty.
