so i know ive seen the thread for this, but i dont know if it was on here or yotatech, and i have lost my password to there so i cant search that forum. anyhow i am looking for part numbers for what is needed, like what calipers and rotors ect, i have been thinking about going with aftermarket rotors like say brembo or stoptech or power slot ect -any advice on that is a plus/welcome as well. i tryed going to a local parts house and they didnt know anything about there being multiple or different calipers for the tundra. i am assuming that the larger 231mm caliper is from a TRD tundra and the smaller 199 is from the standard tundras. i already have the tundra 17 wheels so im good there if anyone has info on this or a link to the thread with all of this info, id love that, i know its out there i just am having no luck finding it.:dammit::ybrick::smashputer:

thanks, that was one of the threads i was looking for. but i know there was another one that had part numbers for both the 199 and 231 calipers, i want the 231 calipers cause i do occasionally tow with my runner and i have been known to drive it hard. besides, id rather have too much braking power(no such thing), than find out i needed to stop 5' shorter one day...

Just ordered everything i needed to do the TBU from NAPA yesterday. I had the gentlemen behind the counter order the calipers with the casting code 13wl stamped on them, as i believe they are the 231mm caliper.

Here's another link for ya. Brakes larsdennert.com

thanks, do you have the part numbers for the rotors and calipers from NAPA? that way i know there will be no mistake(once you get them in and are sure they are the 231 caliper), the guy at the counter didnt have a clue to what i was talking about and seamed to be thinking only about what he ate for lunch at BK or something....
 
I got my Tundra 13WL calipers from a salvage yard, just told them I needed them off a '05 or newer Tundra.

The 231mm rotor was easy, just ordered off Tirerack.com for the '05 Tundra.

So basically just go in and pretend you're ordering for an '05 Tundra. Don't confuse them with the facts.

Here's another thread:
Gen 3 Toyota 4Runner Tundra Brake Swap: Off-Road.com
 
got all my parts at advance autoparts...231 calipers(13wl stamping),rotors and pads.
best mod ever-night and day difference b/n braking power.
total was in the low to mid $400's...just used my old calipers as cores :)

All right here are the part#s:

SE3263 Caliper with hardware Left front
SE3264 Caliper Right front
AD-7877 Brake Pads(Adaptive One)
4886931 Rotor Front Premium X2

My total was $438.xx, but there is a $55.00 core charge for each caliper. Bring them back and get $110.00 back. So $328.00 all said and done. Will be putting the brakes on the runner saturday. I'll let everyone know how it turns out. The Calipers are remanufactured which is nice not only because they have a nice black durable finish, but also have new orings and rubber boots. And the calipers are stamped with 13WL.

so i was at NAPA today and about to order my big brake kit (TBU), told him i had an 06 tundra 4x4 with the TRD package... anyhow he asks me what calipers i wanted, 13wg or 13wl, i told him the 13wl's. we then move onto the rotors, he gave me no option there and i asked him is there an option for rotors being as though there are two diff calipers it would only make sense(i thought) to have two diff rotors, one for its respective caliper... he said nope, his system didnt offer any options. my question now is are the rotors the same,and the only difference is in the caliper? i thought the 231(13wl) had a bigger rotor? im i just going crazy here?
 
The caliper size does not effect the rotor size for this application, the 231mm caliper just has a larger brake pad surface. The rotors are the same for both 199mm and 231mm calipers.

Good to know. By that logic, are the stock 4runner rotors the same diameter as well, just thinner?

Looking at this picture, the Tundra rotors look *very* close to the 4Runner rotors.

Is the main difference in stopping power the addition of Tundra calipers instead of 4Runner's smaller calipers?

The stock 4Runner rotors are 22mm thick at the clamping surface and the Tundras are 28mm. It's been said before that the big difference in braking power is not because of the rotor but because of the added surface area of the brake pads that the larger calipers can hold. The thicker rotor adds to the heat dissipation properties.
 
That's the way I understand it too. Larger pad = larger surface area = more friction = greater stopping power. The thicker rotor can hold more heat (or dissipate the heat better than the stock rotors) which will help it resist warping.
 
old thread but still relevant

i think the number of vanes in the tundra rotors may help with heat dissipation as well.

i'm looking forward to doing this upgrade very soon. i'll be using the 231s on 5-stars. i hate the vibrating:redbrick:
 
uh oh. you guys dont get too worried about the numbers and how it works exactly. they are bigger, they work better, that is all. when you start getting to into the numbers someone always pops up who swears that big brakes are a complete waste of money and cite things like incorrect proportioning valves and all kinds of other bs, but the bottom line is how it feels against your foot. ive seriously had people tell me that the $3k retail brembo kit on my accord is def actually hurting my braking distances, lmfao!!! yeah, brembo doesnt know ****, do they?


but ill play, lol!


the metal is thicker, therefor it can hold more heat without warping. the surface area is larger, which increases friction. the clamping force is now spaced out further, and the bigger rotor edge is moving faster, so you get the rotation and leverage gains there. there are more veins to better disperse the heat, longer life and less prone to fade. they are probably more aerodynamic as well, but not sure. the calipers have larger pistons to spread the clamp force over a larger surface area, and more evenly. these are all of the things toyota considered when they wanted to make better brakes using as many already existing parts as possible, many dollars spent.

the tundra brakes are better in virtually every way and aspect. considering you get inches in rotor diameter, this is one of the most affordable and easiest big brake upgrades of any car on the planet. so count your lucky stars you dont have to spend $1200-3000+, and slap these bad boys on ASAP!!!

LOL I always thought bigger was better :girl:

The rotor is actually the same diameter though, and that's what makes this an even better upgrade on the cheap :hungry:
