Negative experience with EBC Ultimax2 Brake Pads

Installed these pads and new rotors on the front and rear of this vehicle after research on how to obtain stronger braking power on this non-performance oriented vehicle.

While braking power was nicer with more initial bite than the original OEM brakes that were on the vehicle from the factory, there were several issues with the pads described below:

1) This brake pad produces a ton of brake dust, equivalent of what you would see on BMW and Mercedes vehicles. After two weeks of driving, the factory wheels are coated in dark brown brake dust, something you don’t see on Japanese vehicles with OEM pads or Akebono equivalent quality which I’ve used in the past on various vehicles.

2) This brake pad has serious fitment issues. On initial brake pressure, there was a loud clunk of the pads. The pads seemed to shift slightly, causing this terrible noise inside the cabin. I’ve taken the brakes apart twice, and all caliper brackets and calipers were tightened down securely and there was no movement from anything being loose. There was also a grinding sound coming from the brakes as the vehicle was turning with slight brake pressure applied.

3) These pads squeal on stops towards the end of the stop. I’ve lubed the back of the pads again after install assuming I might have missed something but one pad continued to squeal despite all of my efforts.

Final thoughts: Even though, this pad is marketed as an OEM equivalent pad and not one of the higher performance lines that EBC offers with the squealing and brake dust you will experience in those lines due to the compounds, I would not recommend this pad to anyone. New rotors were installed on all four corners, all slider pins were properly cleaned and lubed so a new friction surgace was given for these pads to perform at their best, which they did, when it came to stopping power, but failed at noise reduction, dust and fitment.

I ended up installing the Duralast Elite pads from Autozone. After the initial drive, there was a heavy grinding noise that appears to be normal from the initial transfer layer. After 60 miles of driving, the noise has gone away, there are no squeaks or squeals and no clunking noises coming from the pads. The pads appear to have less bite but we will see as they break in, despite having the same GG rating of the EBC pads.

If EBC worked out the noise and fitment issues, I would learn to live with the heavy brake dust but improved stopping power.

Interesting.

Curious because i was recently considering these or red stuff.

How many miles did you use them and was there any of the break in coating left on them when you removed them?

Does this car have any anti rattle clips/shims ECT and were they reused or did EBC include new or advise not to use?

Ultimately I've found that factory pads are usually not that much more expensive and as long as happy with them to start with, its usually the way to go.

On that vehicle, the owner and primary driver drove for about 3,000 miles with those pads. The red transfer layer was gone after 1,000 miles when I initially took the brakes apart to inspect everything.

The transfer layer is gone after 50 miles I’d imagine.

Shims come with the EBC pads already attached from the factory.

Akebono Street Performance line offers good performance, not the ProAct pads if they are made for your vehicle. The ProAct line are great in terms of noise, fitment, dust and quality but require more effort when it comes to stopping power. Some say that some of these pads have less braking surface area when compared to OEM pads in a side by side comparison, attributing to requiring more pedal effort.

This is the brake dust after several weeks of driving.

I used EBC GreenStuff on Toyota, and the fit perfectly. All performance brakes that have strong initial bite (semi-metallic) will have a lot of dust. That doesn’t have anything to do with “Akebono quality.” There are BMW’s and Mercedes with ceramic or low dust pads in the last decade, precisely to attract buyers that worry more about appearance than performance.
IMO, considering I used EBC on Toyota, VW, and on BMW as street pads (I have gheir RedStuff now on rear axle) and their racing pads on track, I would say something is with installation or there was manufacturing defect with that particular set. Which can happen to any manufacturer.

Many ceramic pads have higher friction ratings than semi metallic and most cars braking is limited by the tires.

So while I don't disagree with you, what exactly do you mean by performance? The initial bite and the feel or something else?

I used racing pads with EE rating. Take any GG ceramic pad to track and let me know what happens after one lap.
Initial bite is very important. It will rob you some performance if it is not there. Yes tires are the most important safety variable, but poorly executed brakes (I would put ES350 here) are still poorly executed brakes, whether you have Douglas whatever on wheels or Michelin SuperSport. Same goes other way around. Bad tire won’t make my Brembo’s on BMW work any better than those Brakes on ES350.
So, those are basics.
I used EBC specifically to improve junk that comes on Toyota. And it worked excellent. Another option, if available (i got it for Toyota on RockAuto) is Pagid, semi-metallic ones. Also, excellent results. Dust is there, but also they bite if you look at them. They don’t fade at all, they bite aggressively after several extreme stops etc.
 
Sorry you had bad luck with the EBC pads.

Another one that seems to be worth trying is the Pagid Silver pads from Rock Auto. They are ceramic pads from a reputable Euro mfg, and they usually ship from the same warehouse as the Powerstop Geomet rotors.
Not sure about their ceramic stuff, nor I am interested to find out, but semi-metallic ones are absolute blast.
 
According to the all knowing tube of you, Lexus ES350 2016-2018 does have anti rattle springs in the caliper bracket.


EBC Ultimax 2 are organic pads. (No Metallic)

That does appear to be quite a bit of dust for a "few weeks" (how many exactly is a few and how many miles in a few weeks.)

EBC Brakes is/was a member her maybe they will chime in.

So on the road (not track), are you saying that some EE rated semi metallic pads will have shorter stopping distance than GG rated ceramic?

And if the answer is yes, is that because of the initial bite and / or something else?
 
Also is it a few weeks of uber service, amazon delivery driver, or a highway commute?
This is both city and highway miles with 400 miles after the vehicle was washed.

I’ve noticed that during more aggressive stops, there will be a thicker layer of dust on the wheels.

This car is not driven aggressively by any means.

OEM anti-rattle springs were used during this install
