Hard to find Specs, Info & Measurements on 231mm 13WL Tundra Calipers & Rotors

I'm going to be doing this upgrade shortly with the split 3 spokes and the 1/4" spacer. Actually, I'm thinking of having the shop at work make me a set of 4 hub centric spacers out of aluminum and I'd get them anodized some ridiculous color like purple (to keep the g/f happy while I spend money.)
It seems like people are swapping the studs but I have no desire to do this. The only mention is to get better bite during wheel installation. If that's the only reason then I'll stick with the stock studs. 1/4 less thread in the nuts isn't going to make much of a difference regarding ability to hold torque. What is it, 2.5 - 3 threads? Thoughts?

Any thoughts on this? I need to tow a 3350lb Ford Focus ST on a dolly next Friday and would like to upgrade the brakes before I do this (they are ready to be done anyway.)

In my non-professional opinion, you will be fine...When you put a larger space on you remove at least that much thread anyway to hold the spacer on, which then has its own threads to hold the wheel on. Like you said, you will not be losing the ability to hold torque.
 
I know that. What I was saying is when you put on a wheel spacer with its own threads (NOT the 1/4"), just to bolt the spacer on you lose some thread anyway. You will be fine.
 
Unless you run a large spacer like 1.5" or larger. It uses the studs on the hub to connect to the spacers and then has new studs with the full length:

I just reserved pads, rotors and calipers from napa. They have a sale on right now plus a 10% discount if you reserve online. With fluid and taxes it will come out to $334 done.

Also ordered and overnighted a set of 4x 1/4" spacers and a front sway bar bushing kit from offroad wheelers. Total in hand price of $479 to take care of two jobs.

NAPA is also doing a bucket sale where you buy a $4 bucket and get 20% off anything that fits in it. Just fyi if you didn't know about it. I just bought my calipers using that sale.
 
Crap! I missed that post and they said nothing at the store when I picked them up this afternoon. Oh well, complete set of brakes plus lines and fluid for $350 ain't bad. Job was easy and only took extra time because both wheels where rusted solid to the rotors and one of the brake lines rounded.
 
For those saying that cannot get a firm pedal with the tundra brakes.. you guys are pre-filling the calipers off the truck right? 4 pots can be a pain in the arse if you just plop a caliper on the truck and try to bleed them.

How would you recommend doing that? Pull the plug off the caliper, pour some fluid in, put the cap back in and install the caliper? And when you go to put the brake line in the caliper just pull the cap real quick and thread the brake line in?
 
It is slightly more of a pain on a vehicle with a hard line but it is do-able.
- Remove the hard line from the brake line (recommend you replace the soft lines at this time anyways)
- Set the caliper on it's side with the port side up. As you fill it, sort of slosh it side to side and around to make sure any air is released. Do not try to fill it all at once, go slow. Set a towel on the ground and as you fill it, gently tap it on the towel / ground to help release air
- Once it is as full as it can get, then insert the hard line and tighten it. The hardline will be up when installing the caliper so fluid loss should be at a minimum
- Then bleed as normal

4 pots can be a pain as you have to fill both sides. When trying to do it on the vehicle, air can get trapped much more easily than say on a floating caliper with pistons on a single side.
 
I just bled it twice and didn't have to worry about it. Not like it's hard or anything. I bled it once when I put it together and then drove it around for a bit to bring the air to the top. Then I did the FSM procedure and bled it a second time. Solid.
 
I've just bled mine once so far and they are spongy. Will do them again tonight but they already lock up the wheels whereas before braking was merely a suggestion.
 
FYI. I would not recommend the power stop calipers from rock auto. Started to bleed the brakes today and each caliper has a bad deal on one of the pistons. Ended up reinstalling all of the all brakes. Now to wait for rock auto to reply back and get this sorted out.
 
Well, I have braking issues developing.

Just did the swap a few months ago and everything was going smooth. Have about 3k miles on the swap and now I'm getting vibration in the pedal when braking. However, it's very unique. It does not happen under hard braking or heavy downhill braking only under light braking. Under light braking, if I start to press in the pedal there's a "frequency" (for lack of a better term) where the front end and brake pedal vibrates. When I let off the brakes, it is more pronounced. The longer drive the vehicle the more pronounced it gets.

Any idea what's going on? I have:

Toyota Rotors
Toyota Pads
Toyota Shims (greased as directed)
Powerstop Calipers (reman'd)
Torqued all bolts to spec per FSM

Did a visual inspection, no leaks. Reservoir is good. No air in system (bled several times).
