Bolt-On Tundra Brake Upgrade for 96-02 4Runners

[MTL_4runner]

I don't think I'd feel good taking off much more than 1/8" unless it was on a rib boss.

ok, mod all done! got out there at 8am this morning to beat the rain, and finished it by 1030. by far the longest part of this was the grinding on the caliper, a little bit at a time to avoid grinding off too much. i also touched my flap wheel to the back side of the wheel where it was touching, less than 1/16 of an inch removed, and probably alot less than that.

brakes are bled, but the pedal just feels a tad soft, so ill probably rebleed after it pours rain for 4 days. also, i have quite a bit of pedal travel before the brakes engage, this is a rear drum problem correct?

Use the homemade power bleeder if you have access to a compressed air source.
It will help alot with your currently mushy pedal.

Seanz0rz, don't fret, mine where soft too after they were first bled. A few days of driving though and now the pedal is nice and tight!

Thank you very much everyone for all the great info in this thread.

One quick question. Is the S13WE casting number the 199mm and the S13WL the larger 231?

No, it's 13WL not S13WL, but otherwise you are correct.

actually ive found that the larger 231mm caliper has a casting number of 13wl, with no S at the front of it.

Yes, you're right, I read it too fast.
My answer got corrected above.

I did mine this last weekend. What an incredible difference.

The Calipers I bought were from Centrix remanfacturers. What a bunch of schmucks that place must be filled with, because they included the brake pad pins from a 4runner (1/4 TOO SHORT!!!) with the Tundra calipers.

I drove to 5 different locations in Souther California to finally purchase all 4 pins. Ended up having to buy them at 3 different Toyota dealers parts counters on a Saturday while my truck sat in pieces at my friends shop. Why Toyota sells these pins as single items when you'd think they'd be bought in pairs.

2 Junk yards refused to seperate them from the calipers
Toyota of North Hollywood had 2 pins.
Hamer Toyota in Mission Hills had 1 pin.
Keyes Toyota in Van Nuys had 1 pin.

But I got it together easy.

Two things I noticed:
I have the 5 spoke rims, and they did not rub on the calipers.
My dust shield did not require any trimming to fit the caliper, only minor pushing back to prevent rubbing the rotor. It made a horrible scraping noise without doing so. A little mallet on ball-peen and that was taken care of.

well last week i found a leak on my left caliper, coming from where the two halves meet at the top. noticed a nice puddle in my wheel... glad i caught it when i did.

took it off, had napa replace it, when i got the replacement tuesday, correct part number, correct box, caliper was stamped with a big R, DAMN. so they reordered, came in today, same thing, so they called around and for sure got me one, hopefully its right.

the leaky caliper would definitely explain the less than stellar pedal feel and the slight pulling to the right. it will all be fixed friday afternoon/evening.
