The wife says that the brakes feel "funny" after a near-panic stop yesterday and suggests I check them out. I figure after two years and 25K miles hauling our little race car all over creation, I should probably at least look at the calipers and lube the sliders. I'm assuming these aren't any breakthrough radical new design on these things - if they're dramatically different from everything else out there, tell me now before I put on my grubby clothes and head out to the garage!
These have standard brake hardware, right?

If she had to perform an emergency braking maneuver, she probably had her first introduction to the brake booster. IT IS REALLY ANNOYING!
Basically when you brake hard, the truck thinks it needs to brake even harder for you and pushes the brake booster. usually it's not needed when it does it and you get to hang in your seatbelt for a bit and get scared the crap out of you as to why the truck just tried to put you through the windshield.
I'm sure there are situations where people have been very glad with this..... feature.... but in my mind it's set to be a little too trigger happy.
But yes.. otherwise normal. I just had the 30K service done on mine and i had " 4 nickles left up front and 5 nickles in the rear" .. because I guess inches (or even millimeters) aren't a normal unit of measure any more!

OK jacked the tank up and checked everything out, nothing seems out of the ordinary. Had a senior moment as I'm staring at the front calipers trying to figure out how to make the thing swing up and pull off so I can grease the sliders before it dawns on me that four-piston calipers don't actually slide. Duh.
I did get the rears apart, lubed, and put back together quickly and easily so no worries there.
Does anyone know when I should be thinking about new pads? Mine are somewhere around 3/8" left all the way around. I don't want to let them get to the point where we're risking having the pistons get too far out of their bores. Total mileage on the wagon is somewhere around 28K.

So according to the factory service manual, it looks like you've got a lot of life left!

Front:
(a) Using a ruler, measure the pad lining thickness.
Standard thickness:
11.3 mm (0.445 in.)
Minimum thickness:
1.0 mm (0.0394 in.)
If the pad lining thickness is less than the minimum, replace the pad.
Rear:
(a) Using a ruler, measure the pad lining thickness.
Standard thickness:
10.0 mm (0.394 in.)
Minimum thickness:
1.0 mm (0.0394 in.)
If the pad lining thickness is less than the minimum, replace the pad.

Not sure the situation wifey was in when braking but had a weird one of my own, and I'm certain it's not bad brakes. Had to brake hard down hill one day and hit a large pot hole mid-brake. ABS went screwy and the truck felt as if it sped up or jump forward for a brief moment before getting back to braking. Not a fun feeling when some arsehole decides to not see you coming! Luckily he kept his teeth that day and my 4Runner remains dent free.
