2nd Gen Tacoma Big Brake Upgrade

Hello All, I really need help answering some questions regarding my 2015 Tacoma 4x4 DCLB and the Tundra/Big Brake upgrade, for which, I have not been able to find reliable, current info. for this setup, even in this forum. Forgive me if I just haven't looked in the right place.

I am planning to haul a horse trailer and I want more stopping power.

I believe the right calipers to go with are stamped 13WL because they can accommodate larger diameter rotors. I bought some that bolt to my stock spindles, and am ready to get rotors.

Now, the rotors I think I want are drilled and slotted, 13.3" (338mm), which would be larger than the stock 2.5" (318mm).

The question is, is this correct - will these fit?
Otherwise, what size rotors that are larger than stock could I get and how/where can I source them?
Finally, what brake line mods do I need to make to attach to the new calipers? I also need slight extensions, since I'm doing a front Bilstein 5100 lift to the top notch (~2.5").

THANKS!!

 

Here read this.
One thing I will say is definitely avoid drilled rotors, the OP of this thread explains why.

If you want to dig further there are threads on change the Brake booster and master cylinder.
But they require much more reading and studying.

wdunnlee and wi_taco, thank you; these are excellent and perfect threads, which I have thoroughly read.
A couple of questions remain:
- Since it appears that the 13WL calipers will accommodate the 13.3" rotors (which is what I want to use), then why not just go with them instead of the 13WH calipers?
One reason to do so is the ability to just modify, instead of replace the dust covers. Thanks!

 

Good question, honestly I’m not sure.
Both have 48 mm pistons , so braking is (I assume) essentially identical.
Your right jn that the 13WL is more compact laterally, so it’s easier to clear wheels and your dust shield.
My guess is that because toyota supplied 13WH on certain Tundras with the 13.3 rotor size, people assume that it is just better.
Maybe people have done some tests, not sure who the brake guru is, I know @crashnburn80 does a bunch of stuff like that though.
We can see if he will chime in

 

Okay, I'm doing my big brake upgrade with GX470 rotors (13.3") and 13WH calipers (yes, I have large enough wheels (17") for the calipers to clear), but I'm stuck on the pads! I'll be hauling a two-horse trailer that could get up to ~4,500-5,500 lbs., so I want that added stopping power, however, I don't want to go all the way to semi-metalics; ceramics should be just right. So, Akebono or EBC (which color?) or some other brand, is the question? Thanks!

 

In my experience with stock brakes on my 2014 OR, running the TRD Performance Ceramic pads on OEM Advics Rotors, the added stopping power was great, however I found myself warping brake rotors non-stop. I warrantied out a few sets and ultimately ended up removing the pads after 20-30k miles and switching back to OEM Advics pads. No issues since.

So I would caution against going with an overly aggressive pad, but it may not be such an issue when upgrading to a larger setup. For those of you upgrading, I'd recommend Advics.

Coming from my modified BMW, ceramics have great initial bite, but fade quicker. So situations like towing and going down a mountain could be more likely to get sketchy. I don't know if Performance Friction has anything to offer our trucks, but their Z compound pads were an excellent compromise on my street/track BMW to fight off fade but offer superior braking over stock.

Crashnburn did some EXTENSIVE writeups on brake upgrades and his threads would be worth a read.

 

I have the Akebono ASP976 "Ultra Premium" pads and they have worked out very well. Took a long time to bed in, but once they mated up the performance has been great. Quiet, no dust, and lots of stopping power even with all the added weight. Towed a loaded 6x12 UHaul a thousand miles and through hills and braking was never a concern.

 

after doing the tundra swap it was better, but with towing it still was eh. i tow 6k+ a bunch of times and one of the better upgrades was having trailer brakes on both axles. this helped the most, then went with a set of wilwood 6pot brakes and that helped out even more.

 

Op, just to make sure you’re aware of it, why not go with the GX460 rotors and calipers?
They are the same diameter as the gx470’s 13WH, but are thicker 32mm rotors vs the stock Tacoma / gx470 28mm.
This will be better for warping and towing as you intend.
The calipers are stamped 14WA.
I don’t think this exact thread has been linked in this one yet, so I’ll add it in.
Does good comp comparison of stock Tacoma rotors versus the gx470, and the gx460 / 2010+ 4Runner:

This….

OP, Gx470 type calipers have had +/- issues with pistons seizing with age. Skip that and go for 5th gen 4runner/GX460 calipers if you are already rockin 17”wheels. The 460/5th gen t4r calipers are less prone to seizure.

I’m “upgrading” my brakes using the specs in this thread, with OEM calipers. The calipers that are the old 14wa casting are direct fit. Most of those at this point are a reman item.
