Am i overdue for brake fluid & power steering fluid @ 142,000??

The steering's electric, so there's no fluid. As for a brake fluid flush, you may want to leave that to the dealer. Oh, and at that mileage, I would have the brake fluid flushed.

 

Agreed.

 

Second that

 

I will change every drop of your steering fluid right now.... Done. I would wait till 200k to flush that brakes. But it wont hurt anything if you get it done now.

 

Brake fluid's usually done as a function of calendar years. The German cars recommend every 2 years but most of the rest of the industry doesn't worry about it short of 10 or so.
If you can manage to keep things clean, you could change out the brake fluid in the reservoir alone with a turkey baster every few months. The brake fluid does slowly infiltrate the system and this would be a cheap, simple way to renew things gradually.

 

css,

I disagree with your procedure. The new fluid would not get very far and only travels as the pads wear. It might get through the master cylinder, but with the accumulator, the electric pump and ABS valves all in the system,, it will never make its way to the calipers. The calipers are where the fluid meets the heat!

You really need to give the system a proper fluid change if you are going to do this job.
WADR, your method is just a feel good thing.

 

Honda say's every 3 years, independent of mileage. Toyota doesn't seem to mention it.

 

I agree that a full fluid change is preferable but disagree that the fluid doesn't mix.

In a previous life I worked for a brake system manufacturer. One of our OEM customers used their own brake fluid formulation that proved corrosive to their rear wheel wheel cylinders. They ended up with a problem because the iron oxide would migrate to the master cylinder reservoir and stick to the ring magnet in the fluid level float, binding it up.
If the fluid weren't mixing you wouldn't see the gradual darkening of the fluid with time.

 

Lexus recommends brake fluid changes IIRC, every two years.

 

Ditto on two years. I bleed my Jag brakes every two years. Brake fluid is hygroscopic (it absorbs water) and over time you might find it boiling away in a panic stop as the caliper absorbs the heat load off the discs. If the fluid is dark and it's been two years, either bleed it yourself or have it bled by a pro and replaced with new.

 

It is easy to say 'every two years' but the issue is that brake fluid is hygroscopic, it attracts water vapor. As it becomes more watery, it boils quicker (bad) and starts rusting brake parts (bad). If you live in Phoenix it could be decades before it absorbs any water, New Orleans may be 2 years. There is a test the mechanic should do if you ask for it.
