'09 honda fit.... how often do you do a brake fluid flush?

 

Welcome to the club. https://www.fitfreak.net/forums/2nd-...p-manuals.html

 

Every three years is a nice rule of thumb.

 

Thank you. I looked it up online and it looks easy enough for me to do it. Next time I will...

 

Just be careful not to get air into the system. Otherwise, easy to do, but better to be 2 persons if you don't have a speed bleeder.

 

ok i'll look at the video again. it looked like they just took a turkey baster, took out the fluid and put in new fluid -- i was just doing the 1 step rather than flushing it through
seemed easy enough

 

Flushing new brake fluid throughout the system and making sure there's no air is the important part.

Removing (most) of the old fluid and replacing with new at the start just makes the process go faster as you don't have to push all the old fluid through the brake system.

 

ok thanks. in the video it sounded like i could just do that first/one step

 

That's a start but it really only changes the fluid that's there in the reservoir and not the stuff that's further down the line. I'm of the opinion that it doesn't mix very much at all so it's better to get all the old fluid out.

I use a Motive pressure bleeder (ETCG shows a picture of it) and I use it to bleed one wheel at a time, disconnecting it from the reservoir after each wheel to top off the fluid level.

 

I use a Mityvac. If you keep draining-and-replacing until the fluid looks new, you have a "flush" of your system.

 

It bleeds out through the bleeders, right?

 

Correct. As the fluid is pumped out through the bleeder valves on the disc brake, you continuously top off at the reservoir (to keep air from enter the system). Same procedure for the clutch.

My Mityvac runs using an air compressor. The handpump ones may be good, too.
