5th Gen 4Runner Brakes Upgrade (for 4th Gen 4Runner)

[EnduringGuerila]

I have looked across the internet and found a lot of information spread throughout but nothing that was easy to follow.
THIS THREAD was the most helpful. (51 pages of information)
I am only trying to compile all necessary information to make the upgrade easier for everyone.

UPDATE:

Some people are still having issues with the calipers still seizing. This seems highly situational and I haven't taken the time to look for a pattern of causation.

I personally have had 0 issues and absolutely love the added stopping power. (Installed everything in March 2018 and it's currently Jan 2023)

​

This is a very easy upgrade caliper swap.
The mounts are identical and line up perfectly.
4th Gen Sport models (Sport Brakes Package optional on the Limited) have larger front calipers (13WH) and rotors than the SR5 models (13WG) so no modifications are necessary. The rear calipers/rotors are the same for all 4th Gens.
Yes, this upgrade DOES work on SR5 but the dust shield/covers need to be modified/cut or upgraded. (Just like the 3rd gen 4Runner -> Tundra caliper upgrade)
SR5 owners have the option of "upgrading" their brakes to the Sport brakes but these still have the seizing issues.


The 5th Gen calipers have shown less issues with seizing than the 4th gen calipers have. (my front left caliper seized which prompted this thread)
The 5th Gen front and rear caliper pistons are (2.5mm-3mm) larger than the 4th gens (not sure if this is compared to 13WH, 13WG or both)
The 5th Gen front rotors are 4mm thicker than the 4th Gen rotors. (this extra thickness helps with heat dissipation and warping)
The 5th Gen front rotors are the same diameter as the 4th Gen Sport (338mm or 13.307") (SR5 has 319.024mm or 12.56")

5th Gen Front Rotors:
Nominal Thickness: 31.8mm (1.25")
Minimum Thickness: 29mm (1.14")
4th Gen Front Rotors:
Nominal Rotor Thickness: 27.94mm (1.1")
Minimum Rotor Thickness: 25.908mm (1.02")

It is possible to use the larger (Sport) 4th Gen rotors with 5th Gen calipers...
The pistons in the calipers will over extend when the pads get warn down if you use the 4th Gen front rotors with the 5th Gen calipers. It is highly recommended to upgrade the rotors too
It is even less recommended to use the SR5 rotors with the 5th Gen calipers because of the smaller rotor diameter in addition to them being thinner.

5th Gen Rear Rotors:
Nominal Thickness: 18.034mm (0.71")
Minimum Thickness: 16.002mm (0.63")
Outside Diameter: 312.166mm (12.29")
4th Gen Rear Rotors:
Nominal Rotor Thickness: 18.034mm (0.71")
Minimum Rotor Thickness: 16.002mm (0.63")
Outside Diameter: 311.912mm (12.28")

Both 4th and 5th Gen rear rotors seem to work. Proofs:
5th: BlackWorksInc and measurements, Runn4est, JeffMerr, verman84
4th: 084RUNNAH,
The argument of why it might better to use 4th gen rotors: pjbrownva
ACDELCO 18A2735 (5th Gens) Center Hole Diameter 107.95 MM
ACDELCO 18A1227 (4th Gens) Center Hole Diameter 106.17 MM
That is the section of the rotor the emergency/parking brake uses like a drum brake (brake shoes press against the inside of the rotor)



Here are the other vehicles with the calipers we're after.
Front Calipers: 14WA

• LEXUS GX460 2010-2015
• TOYOTA 4RUNNER 2010-2015 (THEY CHANGED THE FRONT CALIPERS OF THE 5TH GENS STARTING IN 2016 which will not work)

Rear Calipers: F14 and braket 14B?

• LEXUS GX460 2010-2017
• LEXUS GX470 2003-2009
• TOYOTA 4RUNNER 2010-2017
• TOYOTA SEQUOIA 2001-2007

If you are debating whether or not to change the rears in addition to the fronts: Slowgoat here verman84 here M1911 here

When buying calipers, you'll usually have these options (source):

• Unloaded - Caliper
• Semi-Loaded - Caliper, caliper mounting bracket, hardware, no pads. (<-- Recommended)
• Loaded - Caliper, caliper mounting bracket, hardware (shims, sometimes bolts, rubber thingies, metal retainer thing), pads

Most calipers do not come 'finished' and will rust quickly. I highly recommend painting them, properly, if you do not buy them already painted.
JeffMerr and pjbrownva (with pictures)


Brake Pads:
4th Gen (Sport and Limited models) Have the same pads as the 5th Gen 4Runners (source1)(source2)


Wheels:
17" wheel recommended. Some aftermarket 16" work (like the FJ Cruiser TRD Pro 16s) but stock 4Runner 16" wheels will not. (source)


Brake Bleeding: (See Post #2 in this thread)
Brake Bleeding section of 4Runner repair manual. Link to PDF

I can't find any Speed Bleeders that claim to work on the 5th gen calipers. They may be different based on the (re)manufacturer.
Centric Front (141.44287 and 141.44288) Bleeder is 7mm x 1mm
Centric Rear (141.44587 and 141.44588) Bleeder is 10mm x 1mm
Duralast Front D6278 and Rear 19-B2737 calipers: 10mm x 1mm
Cardone(Wearever) Rear caliper Bleeder is 10mm x 1mm

Speed Bleeder(brand) (their website):
pjbrownva here ordered Front: SB7100-SS Rear: SB1010-SS Order Total: $70.00
DoctorMegaly uploaded a video on YouTube. He also used SB7100-SS for his front calipers (7mm x 1mm)

3/16" hose recommended for most nipples




My personal installation guide... (didn't have time to document, bought [FONT=Arial, Helvetica, sans-serif]PWR-KC138-36 and stainless braided Front and Rear lines[/FONT])
Let me know if I left out any helpful information and I'll add it to the original post.

How to fix spongy brakes:

...
See the attached pages from the FSM.
...
I've been through this (with multiple caliper changes) and here is what I found works for me to eliminate the spongy pedal.
Ignore the content in the document about the tester.
It's an electric MC pump so start by bleeding with the ignition ON, engine off. The order is somewhere in the document.
Even with a good bleeding you need to finish with step 2a & b (or 5a). If you have previously done a good bleed then skip right to this step. Do the following with the ignition OFF. They say depress the pedal 40 times but here is where they are short on detail. Forty quick on/off cycles is a waste of time. Do 15 or 20 second cycles. Think of how slow air bubbles travel in brake fluid. Depress and hold the brake for 20 seconds, then let go and wait 20 seconds. Imitate the normal braking stroke as if driving. Repeat 40 times. The pedal may bottom out but hold it there. You will feel the pedal go solid at around 20 cycles but don't stop the cycles there. Do 40 cycles. Give yourself 30 minutes to do this.
Repeat as needed over several days and your brake feel will return.

Hope this helps.

[aquilon]

great documentation. This should be a sticky!

 

[Runn4est]

This is a great consolidation!

I'm glad you made mention of Blackworks post on the rotor bore size. I've seen a lot of skepticism lately on the rear 5th gen rotors being used. People have claimed to me (even after I successfully installed the brakes) the e-brake wont work properly...I can confirm that I am successfully using 5th gen rears with no issue and the e-brake works as intended.

 

[ndjose]

One correction though. The larger brakes on the Limited were an option. I had to bend back the dust shield on mine (03 V8 Limited)

 

[ndjose]

Also, i believe you need 17" rims to clear the caliper, so with the SR5 it can be an issue.

 

[verman84]

Awesome job.

Everything you wrote is a great summary of the process. My suggestion is to go with the 4th gen rear rotors. I went with the 5th gen and the access holes to the parking brake tensioner star nut don't line up entirely correctly. Go with 4th gen rear rotors.

Also, I would make this super bold and large. Paint your calipers or buy them already painted. These things rust ridiculously fast. Mine turned orange in a few months tops and I don't even live in the rust belt. Really wish I had painted them.

I'll rephrase it then. Everyone that has a Limited seemed to have the 13WH so I assumed it was standard.

I already mentioned this in the "Wheels" section. It isn't very large so it's probably easy to overlook.

I'll try to word the recommendation so it sounds more motivating haha

I just did this upgrade. What a difference in braking. The installation is straight forward. The Gen 5 rotors and calipers go right on.

Great summary! Should be a sticky!!

 

[tv4184]

Nice the video by DoctorMegaly is actually my former roomate. I was up there visiting when I picked up my 4th gen and drove it back here. Small world! I saw there was another video of someone else doing the 5th gen swap that was a bit longer too.

 

[N4RNR]

If I want to change out my SR5 dust shields to accomodate the 5th gen brake mod, should I get the 4th gen Sport dust shields or can I just get the 5th gen dust shields. I'm assuming 5th gen dust shields will fit, is it identical to the 4th gen Sport dust shields?

I know most with SR5s just bend them, but I don't mind doing a little extra work to put the bigger shields on.

5th gen to 4th gen brakes

I swapped my 2008 SR5 over to 5th gen brakes (rotors and calibers) almost 1.5 years ago without any issues. It bolted right up without any adjustments. I just bent my dust shield out of the way and haven't had any issues with it since.
I used Speed bleeders SB 7100-SS M7x1.0 and SB 1010-SS M10x1.0 to bleed the system afterwards.
I didn't have any problems using the 5th gen rears and aligning up the hole to adjust the e brake.
It really significantly improved the braking on my 4th gen. It was well worth it.

The 5th shields aren't really an upgrade. I personally recommend just bending or cutting them and spend the extra money on something else.
I used a Dremel when I upgraded my 3rd gen 4R to Tundra calipers.

Don’t breathe the brake dust in from dremmeling the shield. There is asbestos in brake pads and the brake dust. Wear a mask please. Spray it down well with brake cleaner.

A good friend is in the final stages of dying from asbestos dust. It freaking sucks bad. I want you to be healthy man.

Thanks for this and everyone who contributed to all the other threads referenced here. So awesome! I'm in process of ordering all the parts now. Over $1000 worth.

I'm a bit slow and I was still a little confused on the hoses from Centric since GLW68 listed both rubber and stainless hoses from Centric, as well as two other hoses from ACDelco. I put together this little chart on Centric hoses to hopefully clarify things for anyone else confused on this.

Note, there are 6 brake line hoses required for the 4th gen 4Runner. However, when using Centric’s parts catalog search feature for StopTech Stainless Steel Lines, the search results reveal two types of hoses (007 and 507) for a total of four hoses. There are no stainless steel hoses available from StopTech (by Centric) for the rear uppers. Therefor, if you want to go with Centric hoses for the rear uppers, you will have to go with 150.44397 rubber hoses.

rubber hoses from Centric

2 Front - Centric 150.44362
1 Rear Left Lower - Centric 150.44408
1 Rear Right Lower - Centric 150.44407
2 Rear Upper - Centric 150.44397

stainless steel from StopTech (by Centric)

2 Front - Centric 950.44007
2 Rear - Centric 950.44507

Alternatively, you could order the G-Stop Brakeline Kit (part #21186) from Goodridge which comes with 6 stainless steel hoses. However, some have reported this kit to be more of a pain the ass to install.

Also note, when searching Amazon for brake lines from Centric, you must use the period [ . ] in the part number. Some people here list the parts without the period, but the search results on Amazon will come up empty.

 

[r32]

Would also like to add clarification on the Centric calipers.

Centric 141.44287 (front right)
Centric 141.44288 (front left)
Centric 141.44587 (rear right)
Centric 141.44588 (rear left)

vs.

Centric 142.44587 (rear right)
Centric 142.44588 (rear left)


141 series = Semi-Loaded Calipers
142 series = Posi Quiet Loaded calipers

CALIPERS - Centric Parts

142 series

• Zinc Dichromate finish, or O.E. colored powder coating
• New hardware
• New piston
• New boots and seals

On the Centric parts catalog website, I could not find 142 series 5th-gen calipers for the front. On Amazon, it shows about a $45 difference in cost between 141 and 142 series calipers.

 

[DreamRun08]

I have really bad uneven brakepad and rotor wear in the rear. Are tge calipers the problem or could it be something else?

This was my plan, but to order Crown ss lines. Where are you seeing they are a pain to install? They shouldn't be any more difficult than a rubber brake line I would think...

Someone on the forum did it already.

Kind of sucks cuz I need the center lines but they’re sold as part of the kit. I have extended rear lines and the fronts are going to be from my stoptech kit.
