Warped New PowerStop Rotors 😢 (1 Viewer)

[bgladd]

I've always had great luck with PowerStop: I installed them on my '09 LC and '06 GX470 without issue. Smooth as butter.

But, I replaced my front rotors & pads with PowerStop rotors and pads on my '13 LC, and they warped immediately. I replaced them again a few months later, and they warped immediately. What could cause this? Bad caliper? The truck doesn't pull left or right when I apply the brakes.

Thanks for your wisdom!

Pad material deposition on the rotor surface.

Basically, your pads aren’t compatible with your driving style. You are frequently enough coming to a full stop with sufficient heat in the pads to transfer to the rotor. This thicker area then causes more heat in that spot on the rotor during normal braking, increasing pad transfer, and you have a positive feedback loop.

Different pads could help. Taking more care to avoid hot pads sitting in one spot on the rotors is another avenue.

In general Warping is from High Heat from excessive braking or glazing the brake from frequent use. If you live in San Francisco it's common with all the hills.

I have had the same issue, but I have been using Toyota Rotors and they have been warping. I think the same company makes both PowerStop and OEM.

This think this is some crap metal used in the manufacture of the Toyota rotors though.

Here is a pic of one of my rotors.

Any thoughts on this?

I'm thinking of sending them back as defective. This is a Florida vehicle, so no salt, ice or snow.
The metal is coming apart, or flaking off.
Toyota OEM Rotors.

Unless you have evidence that the "OEM" rotors are manufactured in Japan, I call on this.

Here is a pic of a legit OEM LC200 rotor:

In Texas under high temps and humidity conditions similar to Florida I have zero problems with Toyota parts on my 24k miles LC200. Granted it is the 2021 (believe 2016+ has bigger rotors/brakes).

Overall, are you sure you have used legit Toyota rotors and pads?

I used PowerStop rotors/pads. I have the exact same set on my other LC, and they are perfect.

I had the same issue a few years back with the Powerstop kit. Ended up trashing them for some solid Centric rotors and was fine after that....kept the pads.

A lot of it comes down to bedding them properly. You may be able to go out and do a rather aggressive rebedding on what you have, and see if it smooths out the "warped" deposits.

My advice in this case; Keep buying Powerstops and let me know where I can buy some shares of that company…

What are you talking about?

This is the "Toyota Rotor" I purchased from the dealer. The Part number is 4351260210.

And it looks like this... and it's warped.

 

[2021 LC200]

That looks like surface pitting underneath the brake pads as a result of the vehicle sitting still in rainy and corrosive conditions like near the sea. Braking will feel like intermittent or "warped". Even OEM rotors will do this given enough time and weather/environment conditions.

Is this the same issue on your Powerstops?

“Warped” is a misnomer here. What most people think are actual warped aka rotors with runout, are actually just the rotor changing thickness around its circumference. Not always, but very often.

Same, only ocean isn’t needed so I wanted to point that out before someone says that condition wasn’t present. I’ve had this from temp inversions that leave concrete and other surfaces slick from condensation combined with my truck sitting for two to three weeks at a time.

Oem rotors and pads are made by ADVICS and is a core component of the Aisin Group.

Brakes need to be either lightly used or at minimum pads swapped for anything more. Huge weak point of the platform. That and efficiency / range are probably what i would call unusably bad territory.

I find the brakes on my 21 LC200 quite powerful to the point tire to road grip is more the issue and vehicle weight.

Even towing our 7000lbs travel trailer and having had intermittent issues with the electric brakes has been fine, although not good at all ofcourse and made me anticipate even more.

I would expect Toyota sized them well for ATRAC purposes.

Having said that, the 200 is never going to feel like it brakes well compared to many vehicle out there let alone a BMW or equivalent because of the combination of softer offroad suspension, sheer weight at 5800lbs and relative short wheelbase for its weight. Its all-round capability is hard to beat though.

What are you talking about?

I am questioning your assertion that the Powerstop rotors and Toyota OEM rotors are made by the same company.

Are you still suggesting that Powerstop rotors are made in Japan by ADVICS of the Aisin Group?

What ive realized overtime is the brakes are at their thermal limit. There are better dynamics to be had and the factory pads are pure garbage, but additional stopping force and fade resistance is pretty much at its limit with the undersized and low power oem fitout. Single pot out back is kind of wild when you think about it.

Sure grip is limited, but a 275 / 285 is also kind of small for performance driving a 7,000 lb suv. This is where the G63 kind of shines.

Powerstop is hot garbage. Never been impressed but have been seriously let down by them.

I stick with Stoptech/Centric for rotors and Stoptech/Centric or Hawk for pads.

Probably not warped, just runout issues due to uneven brake pad material distribution. Does powerstop have bed in procedures listed, and did you follow them? If not google brake pad bed in procedures and follow them to a T. I bet you one car payment that fixes the issues.

Yes, I followed the procedure!
