The JOD believes in the principle of diffusion and all, but thinks in the real world it's more applicable to a system with rapidly traveling, re-circulating fluid and bigger lines, like power steering. The effect The JOD noticed doing this on brakes was very, very small (the amber fluid at the caliper briefly turned to "mixed", then all blue).


The JOD doesn't really like this, since it gives the appearances of the fluid being changed, and maybe leads to a bit of a "false sense of security", and now really questions if it's "better than nothing". To each his own, but The JOD will continue doing full flushes every 2-3 years and calling it a day.


The demar agrees.

Trav says. Don't sweat breaking a bleeder screw, it wont let air in so you wont be in a worse situation.
Just spray the screw overnight with PB. Kroil, Liquid Wrench etc then use a deep socket slightly larger than the bleeder.
Tap the socket with a small hammer 25-50 short quick blows to loosen any rust and work the PB down the threads, you want to hit the caliper right near the threads not the bleeder.

Take a small wrench while keeping slight pressure on it tap it with a small hammer repeatedly instead of exerting brute force on the bleeder.

Trav uses an air tool designed for this job but its the same principal and it works.
Trav recently removed some 17 yr old Toyota bleeders that have never been touched as far as i can tell or its been a very long time here in the rust belt.

This is the air hammer tool.

Oh yes... a turkey baster flush of the brake fluid can certainly mix and benefit the system. Thee is a lot of movement to mix eventually.
It has even fixed problems in my empirical experiences.

Turkey Baster Brake Fluid Change is not as good as full flush from bleeder screws, but it is better than doing nothing.

Thanks for the suggestion.

I got some quarter inch tubing which is not stiff. (Tubing that is used on oxygen tanks). See if I can attach that onto a pump of some sort. Perhaps a pump off of a hair spray bottle.

I'll dig this stuff up and give it a try as soon as it stops raining up here in the Northeast.

Or just siphon the fluid out with this long tubing. What the heck, I've been know to make a mess or two. lol.

[censored], That tubing was to stiff. Was able to feed it over into the reservoir but wouldn't dip down into the fluid.
Will have to try something else.

Alright. Once I get the 2 long highway runs in the next couple weeks out of the way, I'll see what happens if I try to loosen up the bleeder screws. In the meantime, I'll definitely hit them with some PB.

Might do again for the PS reservoir......... with a cleaned out or another baster. Better buy a new one for your Thanksgiving dinner (LOL).

BTW - bleed screws need little more than finger tight. Maybe 5 - 7 ft/lbs. A flare (line) wrench is best.
X2 to everything this guy just said.

MVA agrees with the Professor's recommendations. MVA does the turkey baster plus a full gravity bleed every 3 to 4 years.

To be really through, on a vehicle with old brake fluid, after the first bleed, MVA would go out on a wet or gravel road and activate the antilock brakes. And then he would bleed the brakes again.

^ I did do the ABS thing between the 2 turkey baster changes.

The JOD did this on a friend's CR-V that hadn't had a brake fluid flush during its first 8 years of life. The JOD went out to a wet parking lot to "open up the ABS module" after bleeding (with plans to do a second bleed). Then, he learned a really important lesson: not all cars made in '03 came standard with anti-lock brakes shocked2 shocked2 blush duh duh

The JOD won't be making that mistake again anytime soon...

I've been doing this for many years(with each oil change) with very good success. I also do the PS pump as well.

Some comments about brake fluid change using turkey baster

1) I realized that my turkey baster leaks pretty badly at sucking the brake fluid from the reservoir
2) There is NOT much fluid in a typical reservoir to extract; no more than couple of ozs before I started worrying about getting the level too low and introducing air.

Do you need to stay away from dollar stores when I pick up my turkey basters?

Go to the local decent drug store and get a 'booger ball', the blue/green rubber suction balls (for noses) the hospitals give you when you have a baby. Seriously. They are the best things for suctioning master cylinders; they are impervious to brake fluid and the nozzle is pretty thin so it gets in to smaller areas like divided reservoirs.

Our initial pediatrician was a Porsche guy, we got talking cars and he sent me home w/ a bunch of these.
