4Runner Brakes

2004 4Runner Brakes

I haven't been able to find anything in my literature about the new 4Runner's brakes. That is, whether 4 wheel disk or rear drum, and what size they are. Could someone address this? People on an RV forum I'm in have said that SUV brakes in general aren't up to the task of slowing a travel trailer going down long grades.

Somewhere I thought I heard the 4Runner was engineered with larger brakes to accomodate demands of off-roading, etc.

Thanks!!

4 wheel disc.

SR5 and Limited get I think 12.6"
Sport get 13.3"

Larger brakes on Sport?

If it's true that the Sport has larger brakes, then it would seem I should go for that above the others - and for the Xreas! I still haven't found anything in the literature though.

It's true and if that is important to you I would go with the Sport.

Did you check the fine print in the brochure? It might be in there. Regardless the Sport does have bigger brakes.

Have you tried looking at this thread for info:

http://www.toyota-4runner.org/showthread.php?s=&threadid=3

(Look under Technical Specifications)

The 4runner brakes are indeed all ventilated 4-wheel disc brakes (cool!). 4 piston calipers in the front (8 total) and 1 piston calipers in the rear (2 total). Electronic BrakeDistribution with Brake Assist are standard features.

Hope this helps.

Sport Brakes

Thanks Thai! I see in the tech specs where the Sport brakes are bigger.

So what does all the things you posted (ventilated, 4 pistoms per, etc.) mean in terms of braking. I assume this means that the vehicle has superior braking ability, and that this would be better for towing?

I have an '03 Sport and love the breaks. Sometimes I drive it like a sports car and the break never fade. I have even wondered if I could get the larger TRD calipers for my 4Runner.

Bottom line...if your brakes are strong enough to activate ABS (which is the case for all 4runner models), then brake distance depends mainly on your tires. So, on the 1st stop from 70 mph, all 4runner models would stop the same distance, IF they all have the same tires.

Ventilated discs and 4-piston calipers help prevent brake fade. So, repeated stops are consistent. All 4runners have these two features.

Now, the difference between Sport Ed. vs. others. Bigger brake discs (such as Sport Ed.) means less brake fade also. So, if you were to do back-to-back-to-back stops from 70 mph, the Sport Ed. may stop slightly shorter on the 10th stop. Or if you are towing something, then on the 5th stop, you will notice a difference. This is just an example of the concept.

So, if you were to tow a lot or race a lot on the track, then Sport Ed. is probably a better choice.

Here is an excellent article on stock brakes and aftermarket brakes:

Thanks Thai, that helps a lot - but still wondering what your credentials are, and just why you have so much time for forums (almost more than me)! LOL

Send me an e-mail if you like.

BTW - do you know what type of brakes the newer Explorers have? I can't find info.

Nah, i am just your average 4runner enthusiast!

 

[TeryT]

Yeah, but . . .

OK, just the "average" 4Runner dude - yeah right! But you post some bodacious & length, and I might add authorative stuff on here.

 

[Thai]

Nah, i just read a lot.........not much life on this end of the computer!

I've thought of the larger TRD calipers as well. Does TRD offer them.

Explorer Brakes

FYI: Found out what brakes the Explorer has from another forum:

The 2004 Explorer has 4-wheel disc ABS.
Front - Dual Piston, Floating Caliper, 12.01" diameter
Rear - Single Piston, Self Adjusting, 11.85" diameter

This makes them smaller than even the SR5.

Don't know if they're ventilated like the 4Runner or not. Does that mean that they have the air space inbetween?

Hey cool, I didn't know the Sport Editions had bigger brakes!

I guess to add to this subject,

Carpoint states that the 4runner has a shorter 60-0 stoping distance that the Porsche SUV! 4runner=125ft Porsche=129ft

Hi!,

Where can I buy the TRD calipers? Any URL? Will those fit a 3rd gen 4Runner?

Thanks.

Dealer parts women said that the Sport and the SR5 uses the same Pad (part number), so is it just that the disk is bigger? He said the GX470 pad had a different part number but that makes sense since Lexus uses different numbers than Toyota. Of course she didn't know if the pads looked any different.
