according to a brake mechanic I know..(this is certainly not for ever car)..."some rear brake caliper systems have to drained yearly, especially in high moisture areas..after 2 yrs the caliper piston is seized because of too much moisture in the brake fluid"..for some unknown reason to me, it seems that more moisture accumulates in the rear calipers??
$5 -coolant flush , brake and ps fluid

My daily driver is 23 years old (bought new) and has never had any of its bleeder screws opened. The system has never been flushed nor even bled. Original master cylinder too. All that's ever been done is master cylinder fluid replacement at each engine oil change. Other than pads and one set of rotors I've never had a problem of any kind
I know folks who have smoked 2-3 packs a day for 30+ years and "never had a problem of any kind". Your brakes, like their bodies have damage - you just have to know how to identify/diagnose it.

I think you climate has a lot to do with it, try Canada and your brake lines would've been rusted and needing replacement, hence getting brake fluid flush long time ago
Also, I seriously question the capabilities of your braking system under emergency situations, I would not like to find out the hard way.

Heck, on most cars you don't even have to pull a wheel, just hookup a hose and gravity drain into a container until a few ounces runs out. But to each his own. I tend to look at braking systems as the most important component of a vehicle though.
Exaclty! The only tools you need is something to crack the bleeder. Even if I start with a completly new system, I gravity bleed it first.
Anyone can do it, and it really doesn't take that long.

Now that...was funny. That's going in my sig.

Number one, your truck's PS system only takes ATF not hydraulic fluid.
So good luck replacing the pump.
Number two, you are dead wrong about the brake fluid but hey it's your truck.
Number three, why would even think mixing coolants is a good idea especially if you don't know first hand how old they are.

I think I'm glad chad is not my mechanic.

Love my Motive Power Bleeder. Get the car on jackstands, remove the tires, use turkey baster to remove as much of the old fluid out first, fill reservoir with new fluid, pressurize the power bleeder, and go around to each caliper (farthest to closest from the reservoir) and crack open the bleeder screw.

Ditto, Motive is the stuff. I may be building a DIY pressure bleeder one of these days for S&G but wouldn't hesitate to buy a Motive if it didn't work out.
I found I could do all the brake calipers on any Mk4 VW with the wheels on the ground if the owner didn't need or want a tire rotation, that lops about 15 minutes off. Flossing the 1/4" tubing up to the clutch bleeder was a little more difficult but not much longer than if it were up on stands or ramps.
No need for a 'coolant flush' on cars running G12, extract & refill the PSF reservoir every oil change as well, brake flushes every 2 years with DOT4. Easy peasy.

I've done this. Takes at least 200 ml to get solid blue fluid through each of the 5 bleeder points and it doesn't start turning bluish green until about 150ml or so. Some diffusion is expected but there is zero circulation in a typical hydraulic brake system.
