So having recently done this myself i thought i would write it up, as the other well known brake thread only covers the Peugeot 505 GTI disc scenario.
https://zclub.net/community/index.php?threads/toyota-hilux-peugeot-505-brake-upgrade.17515/
For this conversion you will need,
Z31 Vented brake disc's, 4 lug, NA or in other words non turbo version, very very hard if not impossible to get now in the UK, but plentiful in the states, and available at reasonable cost from some where like Rockauto, which is where i brought mine.
Toyota S12W calipers, available used off ebay or i got remanufactured ones from Brakeparts.co.uk
For the cost involved its really not worth the hassle buying used parts of questionable condition, i did at first, and they turned out to be dogs, one or two pistons in each caliper refused to budge!
By the time you have brought a seal kit, and possibly a new piston or two, you might as well of bought recon ones and
saved yourself all the grief and swearing shenanigans!
Note the considerable difference in size compared to the original 2 pot caliper, hence the need for 15" wheels at a push minimum, they may still foul though, depends on your wheel design.
Brake pads of your choice, but i used EBC Ultimax 2 pads, DP807.
The pad with the metal wear indicator in the middle goes on the inner side of the caliper.
There is another pad that is almost identical in size, but slightly deeper and has different metal wear tags,
and these will foul on the strut mounting ears for the caliper! code for them for reference is DP992.
Ask me how i know that will happen!!!
Brake pad fitting kit, new calipers wont necessarily be supplied with this as standard.
9mm spacer to fit between the hub and brake disc, to centralise the disc to the caliper.
Thanks to Gary (Atomman on the forum) for supplying my spacers, and for doing some extra machining after it became apparent that the 81mm centre bore wasn't big enough for my 260z 2+2 hubs, i posted them back and Gary kindly machined them out to 84mm at my request. 83mm would likely be fine as 84 was a bit loose, but i didn't want to risk them still being tight!
Neither of us had any idea the hubs were different! the innards are exactly the same according to MrF but plainly mine have slightly more girth than Gary's!
Longer brake disc to hub bolts to account for the 9mm spacer, M10 x 1.25mm x 40mm long will do it just fine, it goes without saying they should be high tensile.
The originals were something like 28mm long, i also used allen head bolts, as replacement hex head's can be a bit tight, with regards the head size being bigger than the OEM JIS bolts, and there isn't a lot of room inside the disc mounting area if you have thick walled sockets!
Don't forget some nice shiny new spring washer's as well.
35lbft/48Nm Torque setting.
Brake backing plate/shield will need to be trimmed a little top and bottom or the caliper will foul on the edges. See red line on pic for approximate position of cut.
Around 10mm would probably be enough, I estimated 20mm and that left plenty of space.
You may find that a part of the disc rubs on the backing plate as it now sits pretty darn close, one of mine did a bit at the bottom, so i just bent it out a little.... carefully!
Go easy with the screws/bolts holding the backing plate, I managed to shear one of mine because I was too eager to remove it, and tried to wind it straight out, even though it was binding badly, instead of winding it back and forth to ease it out slowly!
I also replaced mine with stainless steel hex bolts, I definitely wasn't going to try putting the cross head screws back in!
M12 x 1.25mm caliper to strut bolts, the originals can be reused, as the mounting ears on the Toyota calipers
are the same thickness as OEM, mine were serviceable but rusty, so i again used some nice new allen head jobbies.
70lbft/95Nm Torque setting.
You can of course buy all this as a complete kit or part kit from several places in the states, namely zcardepot or silvermine motors

but as with everything pre-packaged, plus the shipping if buying abroad, it'll cost ya!
And finally the finished article
Hope that's of use, if your considering doing the conversion,
Cheers,
