5th Gen Calipers

[084RUNNAH]

Did my first brake job on my truck since buying her new. Since I joined this forum, never really contributed much and just roamed so now I can finally do it. I noticed many of us have the dreaded seized caliper issues and not wanting to deal with this problem again, decided to do some research and took the leap on buying 5th gen calipers, front rotors and pads.

Front and rear calipers are direct fit / bolt on.
Rotors fit without modifications
4th and 5th gen 4Runners share the same brake pads

Calipers are almost identical. Each pistons are 3mm larger
Rotors are 13.30". Only difference with the rotors are the fronts are thicker meaning less chances of rotor warping and better cooling

At the same time I replaced all 6 brake flex hoses with stainless steel extended lines and Dot 4 brake fluid

Now I just got to figure out how to upload multiple pictures

Other than that, brake power increased but the best is not having to deal with seized brake calipers.

Another picture of the caliper. Not sure why my pictures are all sideways

great post, thanks!

would you mind posting the PNs for all six (6) of the SS lines. seems most kits only come with four (4) of them. i have been wanting to all 6 SS lines for a while.

What is the size difference in the calipers? Are we gonna be able to fit 16'' wheels or only 17''?

I was under the impression that the 5th gen Calipers are the "Sport" Calipers on the 4th gens... Honestly never bothered to look, but how are they different?

Only difference I noticed was the brake caliper piston which were 3mm larger resulting in increased braking power.
Caliper size was very close. Maybe a few mm bigger?

The biggest difference will be no more seized calipers. I haven't seen any 5th gen guys having issues with seized caliper issues since 2010.

I would say 17" wheels are minimum size to fit the brakes (Same as 4th generation sport and limited)

I will get back with the extended stainless steel brake lines part numbers I used later today

Thanks for the writeup! I'm about to do mine and I need to do calipers because I think i have the common frozen caliper issue.

Are these a direct bolt up. Anything you needed to do for the install other than normal? Do the brake lines need to be done or will the old work? Also where did you get the caliper's from, part #?

I'm very interested in this because so many have had the 'frozen caliper' issue and this could be a good solution

 

[084RUNNAH]

Yes they are a direct bolt up.

No special tools required.

Brake flex hoses are optional

I'm assuming you had the optional Sport brakes on your Limited?

 

[084RUNNAH]

I had the 13.30" (larger) brakes already but not sure if they came standard on the Limiteds

I see you are using Centric calipers and rotors.
Is Centric the actual Toyota OE Manufacturer?

Thanks for being the guinea pig on this, it is always cool to see people trying new things with their trucks. Do you know what was changed in the design of the 5th gen calipers to make them less prone to seizing?

Nothing beyond slightly larger piston I imagine. The issue is probably going to start cropping up on 5th gens as they get older as it did with 4th gens.

I used Centric rotors and calipers because of their quality. I love their rotors especially. Calipers looked great with the spring clip around each caliper boot.

Based on my search so far, I haven't seen much 5th gen calipers seizing yet and hope they don't. I hope they fair well like the 3rd gen calipers and 13wl calipers from the tundra. Also hoping that the clips around the caliper piston boots/seals help reduce the seizing of the calipers.
