Brake fluid change

If I extracted most of the brake fluid from the reservoir using a turkey baster being careful not to remove all the fluid and risk introducing air, then filled with new fluid and after driving for a day repeated this another time or two, would this be enough to consider the fluid “changed”?

No, that won't get the fluid in the lines, wheel cylinders or calipers.

You need to bleed the brakes properly.

Thanks

So is this because the brake doesn’t “circulate” like coolant?

There are a lot of YouTube guys with videos to help with this, and one that's really easy to follow is Chris Fix.

He has this video to make this tool apparatus to help bleed them yourself:


And then, the actual process:


He has a 2001 Mazda B3000 4x4, so it's really close to my Ranger to cheat off of

Correct. Brakes are just a pressure thing, the fluid doesn't really move much.

Do yourself a favor and pick up a mityvac. As long as the bleeders aren't seized and the hole corroded shut this method only takes about an hour (jacking up the truck and taking the tires off will take the longest) by yourself and you can visually see when the new fluid is being pulled through the clear tubing of the mityvac.

“Hey Guys”

Will check out the ChrisFix videos - thanks! Love his videos, he gets to the point and doesn’t make you listen to him talk about unrelated stuff. Lol
thanks!
