Well, tonight was the big nite!!

Got my Tundra calipers and rotors installed on my 98 runner. What a difference this brake package makes over stock.

HIGHLY recommended upgrade

3 out of 5 monkey wrenches

You'll need:

2000 Tundra front rotors and calipers

Air sander or dremel tool with metal disc

Brake bleeder of some sort

Misc tools, wrenches, sockets.

Basically, you're going to remove your stock calipers and rotors, grind down the inside half moon of metal near the caliper on the dust shield (about 1/16 - 1/8th of material).

Re-install the Tundra rotors and calipers. Bleed the system, drive your truck!

DONE!!!

Total time with air tools and a lift - 1 hour


BTW - If anyone in the San Diego / Temecula area would like to do this upgrade, let me know as I have a connection at Toyota to get you all your parts. PM me for more info!


EDITED - 12/31/2012

This thread is nearly 8 years old. I have long since sold my 4runner and no longer live in Temecula. I realize there may be some additional interest in having this done but I am no longer a good contact point for this.

I'm sure other members here have picked up where I left off and are able to get your needs addressed.

Oh man, you can't drop a bomb like that without some pictures!

Seriously...do tell more. 4Runner brakes are crap, and I have a feeling I have the 15" wheel package brakes. This could be worthwhile.

socal98runner

Sorry, I did not have a camera when the job was done, but I will take some this weekend and point out the details....

HOWEVER, I failed to mention this REQUIRES 16" wheels!!!!!

Now it would be nice if you could reuse the old brakes for a rear disc conversion of some kind.

kevin444

I second that. Damn them drums!

HaveBlue

Ha! That's funny. I was talking to a friend of mine a couple days ago about doing the exact same thing. I think this would be a VERY nice cobination with slotted/drilled rotors.

Alin10123

yes,.. do tell...
I was thinking about going with powerslots/ performance friction pads since they are like TRD pads since they made pads for TRD.
An important thing about warping, dont let anyone take an air wrench to the lugs while they are being tightened. You will definately have warped rotors. Those will overtighten the lugs by a lot.

How much better are they than the 16" stock sport rotors

HaveBlue

They are the same rotors. The Tundra calipers have 6 pistons versus the 4Runner's 4.

A 6-piston caliper with stainless lines, high performace pads, and slotted rotors would be supreme. I have about 3/4ths of that setup. I have the slotted/drilled rotors, stainless braided lines, and EBC pads.

Make sure to get the newer calipers, rotors and pads.....the older style had a warping problem.
I had a pic of old vs new, but the link must have moved.

I was researching on buying a Tundra but I never got one.

Bumpin' Yota

so the big question is will the tundra brakes fit on a 2nd gen's lower end?

socal98runner

They are NOT the same rotors.

Diameter they are the same, Thickness they are WAY different.

As far as slotted/drilled rotors:

Take it from a guy who used to race auto-x. You are wasting your money on those. But if it makes you feel better......

Braided lines are good as long as you flush out the old fluid and go with DOT4 or better fluid.

Pads, you're on your own. Everyone has something different to say about them so I don't get involved. OEM works good for me on my runner.

socal98runner

WAY WAY WAY!!!! BETTER

I can't even begin to tell you how much better the tundra brakes are over the stock SR5 rotors and calipers.

Alin10123

Um... i thought that the stock SR5 rotors were the 15's?

MTL_4runner

I must say it is a very clever idea and I am glad to know they fit with very little modification.
Can you take a pic and post for us to see the end result?
.....maybe even a side by side of the old and new rotors if at all possible?

MTL_4runner

Here is a shot of the rotors side by side anyway:

4Runner or Taco


Tundra


For reference, the inside hub portion is the same size on both.
There may a slight bit more surface area for braking on the Tundra version (this would be fantastic for towing).
I do also believe they are thicker as well which would resist heat warping that much better.

MTL_4runner

As a follow up to my earlier post.....here is the info regarding the Tundra brake TSB.

The front gives you new calipers with a wider spread and entails new backing plates, bearings etc.
The rear gives you heavier drums (I believe same as on 03 Tundra's).

The buletin numbers are as follows:
Rear BR003-02
front BR004-02

If someone can find the actual TSB, go ahead and post it.

Toyota has upgraded the rotor and calipers on trucks built since 9/02

uboatcmndr

This has got to be one of the best ideas carried out on here. More power to ya! I wanna do it my own damn self.

Bumpin' Yota

I just went to Autozone and a toyota stealership and both were about as helpful as a box full of hammer handles....

Can this mod be carried out on a 2nd gen? IF the rotors btwn a 3rd gen and 2nd gen are interchangable as are the calipers then this mod WILL work for us...
