Author Topic: T100 Brake Upgrade (Read 13428 times)

2manytoys · « **on:** Jan 26, 2011, 08:49:39 PM »

For anybody interested in better brakes for their 4 cyl trucks. Upgrading to T100 calipers and rotors were a direct bolt on. Only mod is grinding the backing plates to fit the larger calipers. See pic.

The calipers are similar to regular V6 type except have a larger gap for a thicker rotor. I don't know if the pistons are larger in the T100 vs V6.

The rotors are the same diameter as the 4 cyl and V6 but thicker than both.

They cleared my cheapie 15" chrome modular wheels no problem.

I upgraded to a V6 master cyl.

My stock brakes were scary and I was unable to lock up any wheels. With this upgrade I could lock up all 4 wheels. I had the stock single diapragm booster and it still felt like non power brakes. I just upgraded to a dual diapragm booster and now my brakes are "put you through the windshield" good with very little pedal effort. HUGE difference.

Here's some pics.

i did this same swap out of curiosity one day i had a parts t100 and decieded that since it had zero miles on the calipers breaks and rotors i might as well try it and it worked perfect

will they fit under stock 15" wheels???

yotaneck13 · « **Reply #3 on:** Feb 10, 2011, 08:46:32 AM »

yes sure will plenty of room

i see he had IFS so does that mean to fit these on a solid axle i'd either need the Sky spacer or mount the caliper on the outside of the knuckle??

will this work for 79-85 solid axle? anyone know if they bolt on?

yotaneck13 · « **Reply #6 on:** Feb 10, 2011, 12:58:31 PM »

not sure on that the t100 calipers are the same as ifs truck ones jus bigger so id immagine you would have to do what ever you do to get the ifs calipers on the sa to get the t100's on im curious tho how this works on the sa does the ifs hub swap make the axel wider so you dont have to run wheel spacers or

79coyotefrg · « **Reply #7 on:** Feb 10, 2011, 04:36:58 PM »

yea if you use the ifs hubs then you either have to run the sky spacer between the back of the hub and the brake rotor or you have to redrill the knuckle so the caliper is bolted to the outside of the knuckle ear instead of the inside.

like drill the knuckel where the bolt woult connect it to the caliper?

i'm thinking with the sky spacer and T100 calipers this thing will STOP

2manytoys · « **Reply #10 on:** Feb 10, 2011, 10:33:00 PM »

I'm hoping this works on a SA because I'm getting closer to doing my SAS. Been eyeballing the Sky spacer.

Every time I think I know what I want, somebody comes up with a better idea. Decisions decisions.

whats the diameter and thickness of the t100 rotor??

2manytoys · « **Reply #12 on:** Feb 11, 2011, 03:14:47 PM »

The diameter is the same as the 4 cyl and V6. I had it all written down and don't know what I did with it.

The T100 thickness is about 1" and the V6 is approx. 7/8" I think the specs are listed in product details on Autozone's website.

I used 1995 T100 without ABS to look them up. I'm pretty sure the rotor diameter and thickness is listed. I did not find info on piston sizes however. Hope this helps.

im a guy who dont like to buy anything ill find a product that works and machine my own that way my builds stay lowbudget so if i come up with a spacer that works ill let yall kno and hook ya up

79coyotefrg · « **Reply #14 on:** Feb 11, 2011, 05:44:50 PM »

i put some parts together today and made a jig of sorts to hold a knuckle in my vise. I had 95 4runner front hubs calipers and rotors. If I use a 7/8 inch thick spacer I can bolt the rotor to the spacer then hub and run the calipers in the stock location BUT the caliper is moved out further so the rotor could be larger in diameter. the V6 runner rotor is 291 mm, the land cruiser one Marlin sells is 302 but its not got the same offset or "height" if the rotor is laid flat on a table I need one 302 diameter and 65mm tall, 23-25 thick

there is the easier answer to running taco rotors... use T100 calipers!! no need to grind the inside of the caliper!!!! NICE!

i found the specs, the T100 and SR5 4runner of the same 1995 year model share the same brake rotors and calipers.

only the 95 model of the 4runner?
cause i had 93 model calipers and had to grind them

2manytoys · « **Reply #18 on:** Feb 11, 2011, 09:20:54 PM »

I don't know why some are different. I originally went to get some used brakes from a 94 V6 4Runner and it had the thinner rotors. The calipers had a different casting number too.

I think the ones I'm using have SW13 or S13 WB casting number. I wish I could find my notes.

2manytoys · « **Reply #19 on:** Feb 11, 2011, 09:42:31 PM »

OK, Found some info for casting numbers on a few other sites. I still don't have piston specs etc. They gotta be out there somwhere.

4cyl caliper casting # S12+8

V6 # S12W

T100 ( and 95 V6 SR5 4Runner?) S13WB

79coyotefrg · « **Reply #20 on:** Feb 12, 2011, 01:35:05 PM »

yes, only the 95 runner

yep, S13WB thats what mine have and my rotors are an inch (25mm) thick

Glen,

I hope you figure out how to make this work on your straight axle.

These work great on my IFS and I'd like to make them work on the 85 SA I'm putting together.

Same here im starting to build an 85 sa so ill be looking into it as well hopefully between us we can get something to work/ be safe and be cheap at the same time
