Not completely sure, but I would change it once a year.

I need to do mine..

But to your list, you can also add cabin air filters.
 
My friend sold his 200k miles 1991 Accord in 2007, the car had original brake fluid, AT fluid, power steering fluid and coolant fluid. The power steering and brake fluids were black and color of coolant in reservoir was brown. But the car was running fairly good when he sold it.
 
I change the fluid in my jeep every 30-50k depending on how much I wheel it. Only holds a little over 1 qt, and very easy to do. It is not like you have to lift a jeep to work on it. I do not get some owners.
 
how important are the brake and power steering fluid?

I've never done either on my Malibu although the power steering pump is camshaft driven and I got stuck in the snow last winter and snapped the driveshaft on the pump and had to replace the pump and so it has newer fluid in it because of that.

Never have done the brake fluid but the car seems to be stopping ok. What does changing the brake fluid help with exactly?
 
Inspect is such a bogus term. Inspect and what?

100k is excessive for any gear box.

Brake and power steering fluid are only important if you care to stop or steer.
 
Just like diff fluid, the transfer case fluid should be changed, at the very least, for break-in debris... ideally at 5K.
 
Inspect is a bogus term.

On that note, my brother's honda civic had original coolant until 170K and then he was recommended a change at Sears when it was "inspected". On the recommendation that the original coolant was bad, my bro told them to change it, they must have dumped some OTC junk into it and after 20K miles the whole car was smoking.!!! One can get lucky with long change interval in some departments but definetly not in lubrication department.

One lesson learnt many times, never monkey with OTC coolants.
 
To be honest why change the fluids unless you plan to keep the car as long as possible. Look at all the used cars for sale at the car lots.
 
Our 98 K2500 has just shy of 200K and still has original fluid in the diff, transfer case and transmission. It has towed and plowed snow its entire life. Still going strong.

Just imagine how far it could go with regular fluid changes.

That's harsh! remind me to never buy a used car from you.

sorta...

Not flushing your brake fluid is fine for most consumers. They tend to drive their rides until they're requiring brake service in the form of shot rotors and metal to metal (or when the annual safety inspection states so). There the mechanic routinely bleeds the brakes and adds new fluid. This "every couple of year" bleeding has been what has made the old school mechanic look at "brake fluid flushing??" with a deer in the headlight expression. He's never done it ..and never suffered for lack of it.

Now move this to the DYI'r that preemptively changes pads before the rotors are ever scored and never disturbs the hydraulic system. He can go a decade with zero fluid loss.

Add ABS and whatnot, then you have a decent case for fluid flushing.

I've also seen Vette's that sat in garages have corroded multipiston calipers that needed to be rebuilt due to moisture in the fluid. Routine flushing would have made that very expensive refit unnecessary.

Old school BMW maintainence recommends a brake fluid flush every 2 years. Apparentely it works as neither I or previous owner, knock on wood, have never has a brake fluid related failure in 183,000 miles or 15 years on this car. My car has 4 wheel single caliper disks, ABS and traction control
