TRD Front Big Brake Kit (FJ and 4Runner) is it compatible with 3rd Gen. Tacomas?

Hi Everyone,

I've seen a few threads/posts about TRD BBK but unfortunately there isn't a clear conclusion...

I have a set of TRD Big Brake Kit (PTR09-35130) I had got for my 2015 4runner. It says it's for FJ's and 4Runners, but doesn't say anything about Tacomas.
Looking and measuring the caliper mounting holes, etc. it should fit the 3rd gen. Tacoma.
My local Toyota dealership also told me that they had used them for the 2nd gen. but haven't tried it on the 3rd gen.

I looks as it should fit, but it needs some cutting of the dust shield. So I want to Make sure it will work on the Tacoma before cutting anything and go through all the work.

I do have 17" wheels. I'm thinking it doesn't mention compatible with Tacoma because Tacomas are 16" wheels maybe?? Not sure.

The kit comes with two 4piston calipers with pads, two braided hoses, and two cross drilled rotors and a cut out for the dust shield which I believe is for the FJ and the 4runner. (It's made in the US, not sure by which manufacturers though)

Also if anyone has ever mounted one of these on a Tacoma.... does it need any other modifications such as proportion valve, master cylinder, etc.?

Thank you all.

 

Yes *IF you have the right calipers, there's two different calipers one that uses a 16mm bolts and one that uses a 18mm bolts IIRC.

Yes you will need 17" wheels and even still some may not clear, it's *highly* recommend to replace your dust sheild splash gaurd air duct back plates whatever you want to call them as well.

3rd gen is just a fancy electro gizmo 2nd gen with a econo motor, anyone who tells you differently is compensating.

A new master cylinder is not required but your pedal may sit ever so slightly lower and you may need a little more foot force, this will probably be more noticeable if you have the vacuum booster brake master cylinder over the electric TRD off-road master cylinder.

 

I have the TRD Pro not sure if it's vacuum or electric. But if it were to sit lower and need more foot force, then what's the improvement over stock? Am I missing something?
You also mentioned that I should replace the dust shield? What should I replace it with?
The kit comes with a cutout to cut the lip around the dust shield in order to avoid conflict with larger rotors and use the same.

Instructions also say that I need to use my stock Caliper bolts. Not sure if they're 18 or 16mm.

 

TRD Pro should have the electronic booster, if you have ATRAC you have the electronic booster.

Larger brakes in theory won't fade as soon when heavy braking, or repetitive breaking like in the mountains or towing, they have more mass so they have greater heat capacity and cooling capacity.

The pedal could sit lower as there's bigger pistons in the caliper so more fluid is needed which may slightly require more force as well to move that fluid with the same amount of bite.

As you stated the parts say they don't fit the Tacoma so naturally the instructions are for the vehicles they do fit, what you're doing is retrofitting.

Only sure for sure way to know know about your bolt size is to pull a caliper bolt and see if it fits into the TRD caliper hole, if it doesn't fit no go, if it fits with more than a hair of wiggle no go.

If any of this concerns you educate yourself and reevaluate why you *need* bigger brakes before you start hacking up your truck.

You replace the dust shields with the correct larger dust shields from the FJ cruiser or TRD Pro 4Runner of the appropriate year.

 

Thanks Key-Rei. The purpose of this question is education....
Let me ask you if you've done this on a Tacoma? The instruction don't specifically say it doesn't fit Tacoma. Just say it's for 4runner and FJ. Apparently the previous kits did mention that they fit 2nd gen. Tacos as well (per dealer).
Now, this being for the FJ and 4Runner, it requires trimming the dust shield. So replacing it won't eliminate the need for cutting/trimming. Now I wonder if it still needs replacement of the Tacoma dust shield could be trimmed to meet the clearance.
But going to the need question, since I added front bumper, winch, and other acc. my stopping power has drastically been reduced and I'm also having vibration in the steering wheel which I've been told by dealer that is due to warped rotor (I doubt it is as a result of warped rotor) I'm trying to get rid of. I have a 4runner TRD pro which I was planning to tow with and had got the TRD BBK at a good deal but never installed on the 4runner. So, I though I just put this one to use and mount it on the Tacoma. If it's a complex retro fit and requires a lot of alterations, I wouldn't do it. I'll just get a new stock rotor and pads and fix/rule out the warped rotor problem and live with the fluffy Tacoma brake.

But if it helps with stopping power with minimal effort and modification, I'd rather utilize what I have and improve the braked than resurfacing the stock rotors or getting new ones.

Thanks again.

 

I have put 2015 TRD Pro 4Runner brakes on my 2010 TRD Off-Road, after re-reading your post it appears you may have something different, actual TRD branded big brake kit something like Stop-Tech or Brembo?

Do you have a picture of what you have?

I can tell you I have a 2010 TRD-Offroad so it has the electronic brake booster, I didn't notice a lower pedal or more pressure required but I did notice slightly increased pedal travel for the same bite. That said I also installed stainless braided lines on all four corners at the same time so it's a bit harder to say what changes occoured I compensated for. I've had stainless lines on all my vehicles I just like the firmness and feedback better. Auto X'er thing I guess.

Now I had to replace the dust sheild as the TRD Pro rotors are deeper and have a larger face surface area and made contact with the stock dust shields I could have trimmed them but even still the plate shape was wrong and it wouldn't have covered completely nor ducted correctly so I replaced them with the appropriate ones also from a 2015 TRD Pro 4Runner.

I have 17" SCS Stealth 6 wheels and the brakes clear but there's only about 1/4" in some places, if you have 17 wheels with a deep drop center they may not clear.

Your vibration very well could be from a warped rotor, and if you realize you have lost some brakeing then it may be prudent to do a brake upgrade.

The thing I would check then is pull a caliper bolt and check the fit in the BBK mounting ear hole.

If you have a caliper you could also measure the piston diameter pad face diameter and rotor face diameter to see if you're really getting any greater pressure, or contact, if not then you're really not getting anything more than potentially more mass as to act as a heat sink, which isn't worthless, but not worth the upgrade IMHO especially when it increases unsprung weight.

If you're loaded down with armor though weight probably isn't a concern...

 

This is the kit we’ve been talking about

 

Just posted the picture of the trd bbk fyi

 

Yeah those are different that what I was thinking of.

Might work, might not, don't know the piston sizes or mount sizes, only way to really know is to try slapping them on.

 

Those are pretty cool.

 

is it worth the upgrade? or should i just look into stoptech? 6 vs 4 puck. For the 2nd gen does anyone know if u need to get the 4runner or FJ backing plates also? hoping for a 25% or a 50% like the last trd anniversary sale a couple years back.
