I'm ready to purchase Tundra rotors and calipers for my 2000 4Runner SR5.
Please let me know from what year of Tundra I should be buying the rotors and calipers from. I know we can go with the 199mm or 231mm calipers. Can someone tell me in what year they changed and why. I've been researching here, but there is too much info. I want to go with the large calipers (231mm), since I don't think I'll have a clearing issues with my aftermarker wheels (AR 17").

I'm been looking for calipers/rotors using a 2003 Tundra.... Is this a good year for my 4runner.

Please advise,

thxs,

I am 99% sure that the 231mm were standard on the 03 and up sequoia and tundra. I got my 199's off a 02 tundra but the 231's were available for that year depending on when it was made of if the owner took it in for the TSB.

 

I meant the ones I found on Ebay. NOT the ones that "Beerdrinker" bought for $79.

Yep, my bad....too many ebay ads....I wouldn't buy rotors or pads off ebay anway.

To make a long story short, the 199mm SW13E calipers came standard on most 01-02 Tundras and Sequoias. Late in 2002 they switched to the 231mm 13WL caliper and it came standard on all 2003 and later models. You are not really looking for a year on the truck since the owner may have done the TSB even if the truck was an 01 or 02 model year. If you are shopping, the best way is to use the actual caliper casting IDs to find what size you want for your application. The 231mm sizes are getting to be alot easier to find than the 199mm simply because they are being phased out.


Since we are on ebay......here's a set if someone wants the 199mm version:

I think Kevin444 had a set of the 231mm version for sale, you might PM him:

ok....

I got my Tundra Brembo rotors in backorder,
I'm still shopping for my 231mm caliper...

Do you guys upgrade to stainless steel brake lines???
Which ones do you guys recommend??

TIA,

Ok sorry to pull a old thread from the dead. I am doing the 231mm 13wl brake up-grade. I am thinking that i should get a master cylinder from a 2004 std. cab tundra to max out the brakes on my 4runner. Should i do this? What are the diameters of the boars between the tow master cylinders? I think that it should make for a more firm peddle.

 

Any one?

 

Unnecessary, don't bother.
Just make sure your drums in the rear are in good shape too and use the power bleeder in this thread:

Just thought that i would add this bit of info; the 231mm 13wl fit the stock 5 stoke wheels on my 2000 4runner w/o any grinding. All i did was use tin snips on the dust shield(top and bottom) so the caliper would fit. I think that they stop about the same, but that should get better once the pads seat.

 

I have performed this mod as well. 199mm calipers and stock tundra 16" star wheels. No griding on anything just a little mallet work on the dust covers. DONE!

If you need to change your rotors and pads out this upgrade is a no brainier. The performance of the brakes is a very noticeable improvement.

On a side note I have a box of rotors and calipers sitting here that need a new home.

 

Anyone know if this works with the TRD IS wheels?

 

I want to say it does...but don't quote me too heavily on that. I've got these wheels and will be doing this upgrade very soon. Guess I will know for sure what (if any) grinding is involved.

 

Thanks. My 02' has the 13" rotors. How big in dia. are the Tundra rotors?

 

I bought the rotors and calipers from TAP for about $200 and had them the next day. They are definitely much better but since my rear brakes are oil-soaked my braking still leaves a little to be desired. Once i fix the rear axle seals and brakes I think I'll finally be satisfied with the braking power. 100# a-piece 35's are hard to slow down!

 

I answered my own question. Looks like the 4Runner with 13" rotors has the same diameter as the Tundra (both are 13"). There's no braking benefit here. I'll be using Akebono Carbon Ceramic pads and sloted/cross drilled standard 4Runner rotors when I change mine out.

 

speedy, the benefit it that the rotors will not warp after 13k mi like the stock ones do. I also feel that the truck stops better, stop after stop, when the stock stuff would fade. The bigger brakes help, because they are a better heat sink.

 

This topic has been completely beat to death many times over, but if you ask anyone if they thought the mod was worth it, you'd be hard pressed to have anyone say that it was money wasted and especially if they tow or have a lead foot. Hold a new Tundra rotor in one hand and a 4runner rotor in the other and you'll see why it makes a difference in braking. I'd be the first one to say it if the mod was useless or really had no benefit. Changing rotor diameter is not the only way to improve braking performance and I think you're really short changing yourself just to slap new 4runner rotors on your S/C'd truck.

 

If it's been beat to death, then I'll not add fuel to that debate. I can see how a larger heatsink (read thicker rotor) could help with warping or fading, but wow you'd have to really be gettin' on the brakes to do that (mountains and towing) which I rarely do either. I wish the brakes were stronger on the 4Runner, however a rear disc conversion or larger diameter rotors would be in order for it to be worthwhile for me.

I've got 70K on my stock brakes and they're very smooth with no pulsing from warpage. I've also never been able to make them fade. I do however drive the 4Runner like an SUV and not a sports car so maybe that's the difference.

I'll re-visit this when the brakes need changing, but I'm just not convinced. With the calipers being heavier and the heavier rotors adding to rotating mass those probably counter any added braking benefit, but I digress.

Now if you have the stock 15" wheel'd 4Runner with 11" (?) rotors then obviously this is a very significant upgrade. However, I'd likely recommend 13" slotted and or cross drilled 4Runner rotors for their lighter weight.

Keep in mind I've been fooling with sport motorcycles for a long time and know a thing or two about increasing braking performance.

 

Good luck trying to add logic to this debate. I tried, but it falls on deaf ears. Most bandwagoners on this site can't wrap they're mind around the concept that a thicker rotor does absolutely nothing to reduce stopping distance or brake torque. Tundra brakes are good investment if you tow or drive in the mountains a lot, but thats the only real reasons to blow $300+ on them. Most people have issues with "warping" their rotors because they don't bed the pads correctly or don't torque their lugs properly. I have 180K on stock rotors with no issues at all.

I added some Hawk LTS pads and rebuilt my calipers; I guarantee my truck will stop just as well and in nearly the same exact distance as every other vehicle with the Tundra "upgrade". Cost me less than $100, too.

I even posted an incredibly detailed test Sport Compact Car did with a Toyota Matrix and various Stoptech kits. Turned out that the 6pot front/4pot rear 14" rotor kits stopped the car only a 3-8 feet shorter than the stock brakes in the first five 80-0 stops. But no one here is interested in real data or facts...

 

Interesting.

When it comes brake upgrade time, I'll do some 60-0 testing with a distance wheel. I'd encourage those with the Tundra brakes to do so as well.
