Picked up some 1992 4Runner calipers last weekend from the wrecking yard. If for nothing, they can be some placeholders to get the front axle brake lines plumbed. Ordered some brake pads with “hardware” from O’Really’s. Opened the box expecting to see pins, and the watchamadiggit in the center but only saw a bag with two pin retainer springs. WTF? I guess those and the plates on the pads IS the “hardware” kit.
That's the model calipers I'm running. They seem to work well.

Cool! I think I got the idea from you and the brake thread you may have linked
4Runner Calipers, T100 MC, Rotors and Backing Plate Eliminator install
Had a bad rt. caliper so decided to take the plunge and install 4Runner calipers, new rotors, and the backing plate eliminators I got from Mark Algazy of marksoffroad.net . Purchased Reman Toyota Calipers for '95 4Runner V6 - Part # 47750-35090-84, and 47730-35090-84 (Rh, Lh) New caliper...

Now just hoping I don’t run into too much issue running 15” wheels.
Those calipers rubbed on my 16" wheel with 3.5" backspace. I had to grind on the caliper a tad.

Just as a little additional info for all of us, I pulled out a 60 series caliper to compare to the early 90’s 4Runner caliper.
Using a standard measuring ruler here, so forgive me. The 4Runner caliper measures out to about 8-1/4” in total length, while the 60 is about a 1/2” shorter.
The 4Runner pistons are all about 1-5/8” in diameter, while the two big ones on the 60 measure out at under 1-1/2” with the two smalls at about 1-1/8”.
They do interfere with the rollers I have on currently, so I’ve shimmed them out about 1/4”.

Guess it depends on BS, I was running 4runner or something calipers on my ol' pig with no trouble, but I had 2.5"BS wheels made.
This is interesting to me, where on the rim did they rub? I have to assume the spokes or center of the rim rather than the rim itself?
If you can picture the caliper sitting on the rotor, then the back of the caliper was rubbing on the rim. I also believe backspacing has everything to do with it. I didn't want the tires sticking out anymore than they are now running fj60 axles. It didn't take a lot of grinding, but I had a caliper lock up in the middle of nowhere and had to deal with putting new parts on without the use of a grinder. The only way I know how to fix it is get a 17" wheel with the same backspacing and leave the calipers alone.

They hit the spoke area, or let’s say about an inch to two inches above where the wheel seats to the hub. Not sure if it has so much to do with backspacing as it does having a thicker seating surface on the wheel, or possibly a design that angles away from the caliper more dramatically.
Looks like Toyota was getting more heavily into the aluminum wheels in the early 90’s. Could have a lot to do with the wheel design.

what
1/2" spacer worked to keep it from rubbing.
