I'm just curious, my brake fluid is looking a little brown. Should I just remove whats in the reservoir with a turkey baster and refill it with brake fluid? That is what is recommended for the clutch master cylinder but could I do that with the brakes or do I have to fully flush the brakes?

 

If you look under "Under the Hood" you will discover FAQs, DIYs and all manner of helpful postings.

Do this, just bleed your fluid, you can do it by yourself as I have every 3 years.

If the fluid is funky looking, you need to flush the brakes.

 

Okay, thanks guys. Will be flushing

 

After flushing you can replace the brake fluid in the reservoir once a year. If you mostly street drive like a sensible person, you can drain the reservoir and refill, and you won't have any issues. Just flush the caliper and lines when your change brakes, which is generally once every 3 years anyway.

It's really tricky to fully syringe out the fluid from the reservoir so just replacing fluid by itself is half a$$Ed. Which is why I say if you're going to do that you should start with pretty good fluid to begin with. That way you're not mixing trash and new fluid, but mostly good fluid with new.

 

instead of a turkey baster, use a large syringe (just the plastic, not the metal needle)- they hold suction much, much better than basters. Just reduces the risk of dribbling paint destroying brake fluid.

+1 for just bleeding the whole system. There's at least as much fluid in the lines as in the reservoir, so I see it as contaminating 50% of your fluid by simply siphoning off the reservoir. Putting the car on stands and pulling the wheels makes the job a cakewalk, and give you access to clean the calipers and inspect/clean the suspension while you're at it.

 

I always assumed 'turkey baster' was a verb, and in modern vernacular implied using a more appropriate tool specific to the task, such as a syringe.

Kinda like how we still say roll down the window or dial the phone, when neither of those actions is involved in the task anymore.

 

You'd be surprised what advice people would take literally who aren't yet that knowledgeable. I bought a turkey baster from the dollar store for this task when I got my car... and it's barely any better than scooping out the fluid with my hands.

 

And also change the same fluid in the clutch.
