So ive been doing some reasearch and would like to get down to all the possibilities of what exactly can be done to our first gen 4runners. I just pulled the front brakes apart and found that one of the pots on my 4 pot calipers is stuck.. so this means i need to replace them however, id like to get the best bang for my buck and go bigger!

Currently the truck has a 175 hp rated 22re from lc engineering, and well, lets be honest, with 33's and a hot rod engine, the thing doesnt stop like i want it too.

My question is, does anyone have a write up on if/how the tundra fronts will mount up to an 88 IFS 4runner? ive been searching.. also what iare the wheel size constraints for this upgrade.. any links would be helpful.

Ive also seen the GM caliper upgrades for the rear, however i dont like the fact that the ebrake does not work in many cases. Is there another option for the rear disk?

Thanks!

Probably the biggest two biggest differences is the the radius of the rotor, meaning the Tundra REQUIRES at least 16" rims; and the fact that Tundra rotors are held on by the wheels, whereas the '86-'95 IFS has the rotors part of the hub assembly. It would not be a simple bolt on upgrade like doing it on a 3rd gen 4Runner or 1st gen Taco.

Probably the best option for you is to upgrade to "v6" style front brakes- larger, 4 piston calipers, larger pads and the dual-diaphragm brake booster with the 1" MC bore.

T100 calipers/rotors. T100 stuff uses slightly larger calipers than the V6 calipers and the rotors are thicker. Complete bolt on setup except you gotta trim the dust shield slightly.

Id also upgrade to the 1" master and dual diaphragm booster.

Thanks guys, this is exactly what im looking for. Now my last question is, with the t100 brakes, do i have to step up to a 16 inch wheel or am I ok with the stock 15 inch wheels (I dont want to up grade since i have expensive BFG mud terrains on it as it is)

SCToy

T100 brakes fit with 15 inch wheel.
Tacomas have a much larger spread on the caliper mounting brackets.
I think 5.5 inches vs 3.5 inches, so no chance of swapping them.

SCToy

Go to NAPA, buy their T100 rebuilt calipers, swap in your old ones for the core. like 45 bucks a piece plus refundable core.

The only difference is that the T100 rotors are 5mm thicker and I think all 4 pots are the larger size vs 2 large and 2 small with the older model calipers.

Honestly, if more stopping power is what you want, you need better pads to make a real difference.
I put some Carbotech pads on my truck and that made a serious difference.

Im running hawk pads on the front. what are the options for the rear brakes? the chevy stuff seems like the best route. im no particularly happy at the thought i wont be able to use my stock ebrake if i go with the gm calipers though.. is there another route?

donomite49

you can use an all pro transfer case mounted disc e-brake on a gear drive transfer case

SCToy

Which hawk pads?

benny92lx

Hawk LTS pads. Now will the T100 calipers be too big for the stock master? or will it still work fine?

SCToy

You could get the larger master cylinder if you feel like it. I never installed mine because i am fine with the pedal feel.

I ended up getting a pair of these bad boys and some new soft lines.


However, the bolt spacing is completely different.. they are for a 96ish 4runner, any idea why they are different? from what I understand they should be bolt on correct?

Edit, i see now. i got them for the wrong body style. 95 calipers have been ordered. thangs again for the info!

has anyone checked into swapping 96/newer style carriers onto the older 86-95 axle housing so you could upgrade to the tundra brakes?

edit

did some researching and found that it is one of those more trouble than its worth mods.
the 96 and newer use a rack and pinion steering that i don't think is interchangable with the older system.

Honestly, changing to the 94 calipers and pads made a hell of a difference. before we werent able to lock up the fronts, but with the 94 calipers and pads, the 33's lock up pretty nicely. We lost the brake fade also which is pretty nice. for 180 bucks for calipers, new soft lines, fluid and pads, this was the upgrade we were looking for. I think next in line is the Chevy calipers for the rear.

donomite49

if you haven't already, the 1" bore master cylinder and the rear discs take it up another notch.

gotta check out the dual diaphram booster upgrade myself.

feels good when you make your truck better...

CJM

T100 upgrade (rotors and calipers) will work on all pick ups and 4runners made prior to 95.5. NOT tacoma/3rd gen 4runner, made 95.5 and later.

Or you can use the V6 brakes which are smaller than the t100 stuff.

You cant use anything else on the front unless its custom.

benny92lx

Looks as if the t100 and 2nd gen 4runner calipers are the same calipers. Running the larger caliper right now and will eventually need to get the bigger disk, but this should do for now.
