From my past experiences on heavy duty pads, I have had my old diskus get all torn up and eaten from over abrasive howler chunks.
Been there, myself, just not in this particular platform.
So if your disks/drums are good quality without too much embedded chinesium you should be able to run higher spec pads.
I'm pretty sure they're OEM Toyota at the moment, but I'd have to pull things apart to verify that.
Or just go with the factory grade pads that are likely easier to aquire, cheaper too...
I'm not averse to that plan, but the increased rotational mass of larger tires wouldn't be unhappy about better braking. It's really just a question of whether or not the factory setup is still within its comfort zone, given the overall vehicle mass at current...and I don't have a good baseline for that assessment.
From my notes, Advics 0436 are well regarded (front brakes)
Just looked them up; surprisingly affordable! I'm used to pads costing twice that much, per corner.
If your feeling up to it, a brake booster from 80 series and 1990 4runner/tacoma calipers are considered an upgrade...
Unless there's a gotcha somewhere in that sentence, that sounds like a one-banana job. I managed to bring my line wrenches out here with me, and I even made sure that I have the metric set...so that should be all I need for the booster and lines, if A) the booster is a direct bolt-in, and 2) Toyota builds things like most others do.
Calipers aren't too much of a concern; if they need some kind of weird saddle or something else needs modifying, that could be fun...but on the whole, I'm not too worried about them. Compared to the brakes on my TJ, nothing seems complicated: if I recall correctly, those were discs from an Explorer Sport-Trac, Chevy caliper saddles, shaved-down Dodge 1500-series calipers and a brake pad from Centric that shouldn't have fit any of that stuff, yet still did...and all of that was bolted into a highly-modified TJ knuckle and shoved underneath a 15" wheel. Had about 2mm of clearance between the inside of the wheel and the caliper; tight, but it worked.
When I drive my 2005 Prado 120 series (4 wheel disks) then get into my FJ73, I have a heart attack as the old 73 brakes are just for looks... I rolled through a red light due to high idle and the 3F torque just pushed through all the available braking effort! Super keen for brake upgrade someday (or just replace with new!)
Huh, that's definitely not been my experience; the brakes on mine are pretty good, even with 33's and a full tank. It'll lock all four at 45MPH; I know that for a fact because I did it two weeks ago when someone walked across the road in front of me. That being said: the possibility of running a 35" somewhere down the line means that there's no such thing as too much braking...or too much steering.
On that note: I was under the front end doing the oil change the other day and really just looking around at everything, and yeah: I think I'd like to see a heavier tie rod, at a minimum. Preferable one without pinch-bolts. These haven't really skipped and slipped on me, yet, but that's definitely not my experience with that kind of retainer. Also, I'm not sure about the TREs on this axle, but a bit more beef there might be nice as well; same goes for the drag link. I don't think I need wontons, but maybe a slight upgrayedd is in order at some point.
