New Rotors?

Looking for front rotor suggestions for 2015 TRD Pro. Pull a pop up camper. Stock rotors warped like crazy. In the mountains of Colorado.
Thanks,

OEM.

 

Brake rotors do not "warp". They pulsate because of uneven pad material on the rotor. Regardless, check this thread for the latest and greatest; https://www.tacomaworld.com/threads/brake-upgrade-stoptech-rotors-trd-performance-pads.523829/

 

Best thing is to upgrade to the 2010+ 4runner brakes..

but other then that, I would stay with oem….if you can find them. They are like $50 new.
I am on a pair from autozone, their duralast gold……warped them in 7k miles. But at least you can exchange them as much as you want for 3 years

 

We were installing slotted rotors on the Deputies Units at work. The only difference we found with the slotted rotors we found was when they got hot was they cracked really bad. So we were changing them more often then what the units came with from the factory.

 

Just look for the OEM. TRD big brake kit, this is exactly what you need and you’ll be fine
And rotors do warp owls we have to get them turned every now and again

 

I have power stop rotors on my truck, I don’t tow anything but they performed really well when I went on a 5 hour trip with the bed filled to capacity, 2 people in the front, and duffel bags filling the rear seats. I can’t remember exactly which ones I got but they offer heavier duty rotors than mine. Hope this helps.

 

I have personally turned rotors,,, they do warp. Google is your friend

 

I warped my factory rotors pulling a heavy pop-up down a long steep grade. Guessing around 20k miles from original purchase. Dealt with a shimmy till about 50k miles. Changed brakes and rotors with OEM. Truck now has about 75k.This set has been fine so far. However, I haven’t been down that same grade. If and when I go again, I’m going to turn the trailer breaks up considerably more.

 

Say less.

I've been 110% satisfied with these Stoptechs. Installed them in 2016 and have about 30k very hard miles on them without so much as a shimmy. And also you get the cool factor of having slotted & cross drilled rotors.

So have I. You are cutting the high spots down where there is excess pad material deposited.

 

Learn more. This is a misused term.

 

Rotors do in fact warp. That's why they turn them on a machining lathe.

 

Take a look at what's discarded after turning them. It sure as hell isn't a pile of brake dust good day to you *unsubscribes from thread*

 

I've been a tech for the last 20 yrs.

Pad material transfer happens frequently, it's a legit problem and is often the result of poor driving habits, like holding the brakes hard at the bottom of a hill.

Warpage is also a thing. A poorly cast rotor can have "soft spots" in the metal, less rigid than the surrounding area. In the soft area the rotor gets squeezed making the two sides no longer parallel. Feels just like pad material transfer

Both conditions exist. Both can be fixed by simply replacing the rotors. Nobody turns rotors anymore

The larger issue is the heat that is generated during braking. A tremendous amount to absorb, even when everything is working correctly. Faulty equipment or poor driving habits make it worse

Make sure the rear drums are adjusted properly so they're helping out

Also, if dealing with a persistent brake pulsation, sooner or later sticky calipers become a concern. Sliders need to slide, pistons need to retract smoothly. Is the pad wear even side to side? Any pads worn at a slanted angle?

Look at the brake lines and make sure they aren't kinked or twisted

 

Step 1: TRD Ceramic pads, stoptech cryo slotted rotors, rebuild the calipers

Step 2: higher level: upgrades. 5th gen 4runner calipers (larger), tundra brake master cylinder, possibly same as above parts but larger versions to fit

good with both: stainless steel lines


I did and still use Step 1, which solved pulsation. I want to go step 2 ideally, which is even better, but is hard and costs more.
Stoptech rotors and ceramic pads? They slap right on.
But upgrading the caliper size, brake cyl, associated parts, etc. if you look into it, seems like a lot more work.


I haven't scoured the junkyards or carpart dot com for it,
but any time I browse Toyota stuff on FB/CL/OfferUp/etc. I NEVER see any crashed 5th gen 4Runners being parted out, to even ask if they'd part with the calipers for a decent price

 

Need to find another mechanic. Mine have been turned twice. I still have the factory rotors and drums on my 226,000 mile Tacoma. I'll need new rotors the next time though. But I should get at least 250,000 miles out of them. The drums have never been touched. I've only put one set of pads on the rear in almost 16 years.

But yes, both conditions do exist. And often they can be turned and reused for a fraction of the cost of buying new.

 

I replaced my rotors last year. Slots and drilling are a waste of time and money if you research it. One thing I did want was a coating to prevent rust. The OEM ones do not have this coating and they rust quickly and relatively easily. I ended up finding a nice set of NAPA premiums on sale with the zinc coating and they are very nice.

I also took the opportunity to switch away from OEM ceramic pads too. I went with the Hawk Light Truck ferrometallic pads and I notice increase bite when I really want to stop. Good luck.

Its not excess pad material, it is rotor wear. With excess heat the softer spots in The metal of the rotor wears away, leaving the more dense metal that causes high spots resulting in perceived warpage and pulsation.

Depending on how high the heat is and how much you abuse the brakes you can definitely warp a rotor.

It’s important to pick a reputable company who manufactures rotors and not some relabled foreign junk.

These days good Ceramic brake pads work much better and seem to have less issues than other materials, IMO.

So yes, rotors do warp. I’ve had enough of them on the lathe to attest to this.
