I could have sworn that there is a thread here regarding somr 4Runner calipers that mount up to enhance the front disk brakes...am I wrong or are there any caliper upgrades available?

Here was a good article on this but the site appears now to be nonfunctional. Anyone know the author? Here's a crappy scan but it's all I got. It basically said to use '92 V6 4Runner calipers as they are the biggest pistons but you may need to update your mastercylinder to a larger bore to push enough fluid, your wheeel may hit the larger calipers and you have to trim the backing plates.
EDIT: after re-reading the above link it appears to be the same thing. The scan adds a little more info on how and why. I used these and had to grind very, very little to clear my 15X10 MT Classic II wheels.
The next best may be Toyota Lancruiser Vented Rotor Swap

The 60s already have vented rotors.
I did the 4Runner swap and only had to trim the backing plate. Both stock wheels and the old style wagon spoke wheels fit with no rubbing.
The caliper swap made a noticeable, but not dramatic, difference with stopping but I'm still using the stock 60 series MC.

Yeppers, not a huge difference but a slight one.
If you are having braking troubles with anything under 35" tires, you might want to look at the system itself.
Also, it is not just the runner calipers. Most of the V6 mini calipers (if not all) use the same large bore calipers.
I am running the large calipers on Bob with the stock master.

In hindsight im not sure i needed to use the larger mc. I think the lspv is preventing me from getting full utililty from my braking system, plus i cant seem to keep my drums in adjustment even though i have new hardware in them, i think im just gonna swap in some disk brakes in the rear.
Although the big discount parts houses have them cheaper, the Stealer (at least mine) will accept any Yota caliper in trade for their remans. I tend to trust Toyota & will prolly use their calipers on my 4-way disc swap.
P.S. Is this the thread you're looking for?https://forum.ih8mud.com/60-series-wagons/53498-caliper-upgrade.html

Dieseldog has been very impressed by TLC's "monster" calipers. They're quite expensive-almost $600!
No need to change master cylinder.

Bling yes, any quantitative benefit, probably not. I know people with less than that in their whole trail rig. I wonder how many they actually sell a year and how one justifies that kind of coin for ?? benefit.
agreed.
I am gonna personally run the 95 v6 4x4 4 runner calipers, my cost through work is meerly like 40 bux a pop from o'riely for a loaded caliper with theyre ceramic wagner pads.
I have some calipers that I took my 2002 tacoma that kept when I upgraded to Tundra calipers. Next time I have the wheel off I'll see if they would work....hmmm if the tacoma calipers end up fitting, them maybe the tundra calipers would fit also?
i did the v6 4runner front calipers and monte carlo RDB's, they work well and stop 39.5's better than you'd think. Still running stock mc. I bought an 80 series MC but havent bothered to swap because the stock one seems to do the trick.
S&S -
Should "fit", but the big question is whether the wheel would contact it like with a stock 4rnr caliper.
The mounting bolts are spaced 90mm & the rotor thickness is 20mm IIRC.

Did the 4Runner mod today, but need to get my studs pressed. Looks as though it will fit up nicely with new Raybestos Pro calipers, ceramic pads, and new rotors. Will keep my MC.
4runner calipers in mine...
I can lock my wheels now.

No and No. I've looked into this, had the local brake parts place pull samples, measured various dims etc. Taco & Tundy caliper's are not bolt-on calipers. I've a write-up in mind for when I get the time.
I wouldn't bother with a larger bore MC for the V6 calipers unless you're determined to get back closer to where you started from. The whole point of the V6 caliper swap is to get more piston area, which is more force multiplication. Going to a larger MC bore reduces the force multiplication.

I think the whole question of MC bore goes back to rear discs: when installed with the 4runner fronts they add significant piston area & make the stock MC borderline inadequate.
I'd love to have a local brake parts place where I could look at all manner of Toyota calipers. Instead, I'll have to go to the typical Toyota junkyard where some monkey will tell me "that whole pile is Tacundra stuff" & I'll believe him until I get it home.

Exactly...
If you do not use the parking brake, or crawl under the truck and manually adjust the rear drum brake shoes, your rear brakes are likely not doing anything to help stop the vehicle.
Many times people bring me Land Cruisers and Mini trucks that have poor brakes and they want to spend all sorts of money on upgraded brake components. I adjust the rear brakes for them and they cannot believe the difference in pedal height or stopping ability of the vehicle.

x2. Without upgrading parts, I seriously improved braking performance just by following Mud'structions and the FSM to get adjustment of the rear brakes right. I got little tires though so I may need to upgrade someday when I go bigger

Amen to that. I drove for ten years with the same 1/16 inch of brake shoe material. In other words, it didn't work. Oddly enough, the park brake worked flawlessly, but I could never get the stupid things to work right otherwise. When I swapped axles, I put on rear disks and I couldn't believe the difference! I'm not terrified to tow heavy loads anymore.
