G70 aftermarket brake pads

[Slip_Angle]

I don't suppose Genesis learned a lesson and put better pads on the new models?
This whole "turn and/or change the rotors" is such a waste of everyone's time and Genesis's money. Not to mention, as @Volfy said, the damage to their reputation (and Brembo's).
They should have paid attention and learned their lesson years ago when Car & Driver got severe fade and drove off the track on their first lap with the Stinger.

No kidding. Such a strange decision. I wonder what % of cars end up with the problem overall?

 

[Volfy]

Dunno. Based on my experience, I cannot imagine any owner not getting the same pad transfer, even if the car is driven lightly. The associated question is if their rotors are like mine and don't get any pulsation, how many owners would sense the grittiness enough to bother to bring the car in? Like I said earlier, most of the time just tooling around in everyday driving, I don't really feel it at all. Part of trying to get the most mpg is to avoid touching the brakes as much as possible. Even when I do have to press the pedal a bit harder, the grittiness isn't something that's all that alarming. I can certainly see how some drivers might not know there is an issue.

 

[Volfy]

The cynic in me thinks it might be the dealers milking this known problem for all it's worth, charging Genesis/Kia corporate for changing rotors on warranty claim, knowing full well it's the brake pads' fault, and setting themselves up for another billable warranty claim 6 months down the road.

But as honest and upstanding as dealer service depts are, I highly doubt they would engage in such treachery.

I'm disappointed at the brake pads AND brakes on my 2023 2.0T. With the crappy calipers my car has (even the front ones are tiny), it should have milder brake pads that don't dust like crazy, since any sporting pretensions with those puny calipers are just laughable. And what the heck did Hyundai do with the brakes with this car? I can stop super mildly, and the damn ABS applies the brakes harder, like if I was panic braking, making the car buck, like if I had press the brakes hard, and then release them. They shouldn't do that. It's basically impossible to brake smoothly, which I can do on every other car I've owned or driven before. Super annoying, especially for my wife, which I already got used to super smooth driving, so she's not used to that. Ha ha. I know there are 2 different issues, but just wanted to mention it. Maybe the pads are super grabby, and something milder would disguise that behavior??? Just curious.

That sounds like you triggered the frontal collision avoidance (or whatever Genesis's parlance is for that system). It can happen when you follow the car in front of you too closely and approach it too fast. The car detects the proximity and triggers the brakes for you. And yah, there is nothing subtle about it when that happens.

Anyhow, I did drive the Stinger with the single piston calipers for a while, before doing the Brembo conversion. Pretty sure non-Brembo G70s use the same calipers. There is nothing really wrong with them, other than the fact that the brakes have a very high initial bite when you first start applying pressure on the brake pedal. It takes a little getting used to, if you are not used to a system like that. But there isn't anything right or wrong about it. some cars' brakes are tuned like that.

What I think is that Hyundai used the same master cylinder for both Brembo and non-Brembo systems. Makes sense from a logistics POV. Because the 4-piston front + 2-piston rear of the Brembos take up more fluid volume per caliper actuation distance, compared to the single piston system, the same brake pedal travel pumps more fluid volume into the single piston calipers, ergo the higher initial bite feel.

Or it could just be different type of brake pads.

Anyhow, since yours is a 2023, your brake rotors might actually be the same as the Brembo system. Another forum member here that I helped with Brembo Conversion on his 2022 G70 3.3T found that out. See here: Putting Brembos on a New 2022 G70 3.3T My 2019 Stinger 2.0T came with smaller diameter rotors, both F and R.

I really don't think they are as bad as you think they are.

^ this forum is essentially the same as others i've been on. most of our members are generally more aware of their vehicle's operation than the average driver...in other words, we tend to have an enthusiast bent to us. which also explains why we take time out of our day to read and write about our cars on these forums. as such, we notice sounds/smells/sensations more acutely than do 95% of driver's out there.

so i doubt the symptoms of 'warped' rotors are being reported at an extraordinary frequency on this forum. rather, my guess is that the average joe owner is under-reporting the issue. if it was widespread enough there may be enough critical mass for HKG to need to address it. switching to the Euro pads would solve pad transfer, but we know that part is more costly which is no bueno for the accountants, and the increased brake dust would get noticed by more average joes than pulsating brakes, so then we'd hear complaints about 'wheels turning black'. tough to please everyone, so they focus on the masses and not on us enthusiasts.

case in point: years ago i drove my stepfather's Maxima with a heat shield rattling against an exhaust pipe. i asked him about it and he didn't even notice. it drove me nuts and was noticeable almost immediately and at several spots on the RPM range. i reached underneath and in ~30 seconds bent the offending plate back, which he must have scraped somehow, and the problem was solved. but he could have been driving like that for months or years, i have no idea.

Nope. Nobody in front. And braking with exactly the same pressure. Stupid ABS applies more pressure than I did, then releases. I can feel it in the pedal too. It's the feature called 'emergency brake assist', I think, that when you suddenly stab the brakes, the ABS applies them harder, thinking you intended to panic brake. But we're talking about just slowing down normally, so ABS should NOT intervene at all. Yeah, it's probably a 'idiosyncrasy' of the car, but I don't like it. Ha ha. And I actually brake very mildly, since I'm always anticipating traffic lights, stop signs, etc., so I very rarely stop suddenly, when you could 'confuse' the brakes, and they might try to help.

And yes, I can feel the pads have a strong initial bite for the brief moment they work with my foot's pressure only, before stupid ABS applying more pressure for me. But I don't really want that, and neither the tons of dust they generate, so might change the pads soon (need to investigate for low-dust street pads that have a more linear bite -any tips would be welcome ). Anyway, I'm learning how to minimize that 'bucking' effect, guessing when they're going to kick in, and when they're going to release, but what a PITA. At least I'm braking smooth enough that my wife is happy again, but man, I'm challenging my already excellent brake modulation to the limit. Ha ha. By the way, the 2022 G70 3.3T SP I owned for a few days (with the Brembos) didn't have any of that. Awesome feel, modulation, and power. Now I really wish this 4-banger had those brakes. Oh well. Hopefully a change of pads will improve their awful feel now. Take care.

Sounds like you need to take your car to the stealership, you've got something really funky going on with your brakes.

 

[Volfy]

Yeah, ABS should never kick in unless one or more tires break traction. No way ABS would activate just to help you out. That would only be triggered by the frontal collision avoidance system. If what you describe is true, something is not right. I would at the very least peruse through all the vehicular settings and make sure you understand fully which active safety feature is active and what their effects are.

 

[JCtx]

It's not abnormal. And it's not ABS kicking in; I NEVER said that. I said it's the ABS module, which has A LOT of functions, other than preventing wheel lock-up. That's the module that applies the brakes in an emergency, that assists when braking (probably what's happening to my car, although is should be only when braking hard), applying individual brakes when cornering (called 'electronic torque vectoring), etc.

At any rate, nobody here understands what I'm talking about, and already learned how to mitigate it anyway, so never mind. There's nothing wrong with my new car; it's just an idiosyncrasy I don't like, but there's no perfect car. I adapt quickly to touchy throttles, brakes, and clutches, on bikes and cars, since I have pretty good hand and foot modulation. And I've owned dozens of new vehicles, so it's not like I'm a newbie. Ha ha. Just in the last 5 years, I've owned a 2018 Audi S6 Prestige, 2018 F-150 4x4 Platinum, 2019 Mustang Bullitt, 2021 Tesla M3 LR, 2021 Palisade Calligraphy, 2022 Santa Fe Calligraphy, 2022 G70 3.3T SP (returned), and 2023 G70 2.0T SP. Another 3 years back I got 2015 Accord Coupe EX-L V6 6MT, 2015 Nissan GTR, 2015 Lexus RC-F V8, 2015 Sonata Limited, 2016 Porsche Cayman GTS H6, 2016 Kia Optima SX-L 2.0T, and 2017 Hyundai Accent Sport. And this is the car with the weirdest brakes, but keep in mind I'm a very critical driver/rider, so we're talking about a subtle difference, not a huge/problematic one. Most modern vehicles have brake assist, but you have to depress the brake pedal harder for it to kick in; that's all. I agree Hyundai probably saved some money leaving mixed components on the 2.0T from the 3.3T SP with Brembos. My vehicles with Brembos have had the best brakes by far, and that includes my BMW bike with Brembo Stylemas. But I'm not going to mess with my brakes, other than maybe replacing the pads with milder ones for less dust and less initial bite.

Ah....makes sense now. I felt like I was missing something. The same thing happened in another thread
I guess he blocked me for some reason.

He's okay. A bit difficult to understand sometimes, but mostly harmless.

Other forums have participants that make this one look like a bible study class.

I agree! Some are absolutely brutal.
I would like to know what I said that made me worthy of "blocked" status.

Dunno. I do remember there was a recent discussion (over premium gas IIRC??), in which he got pretty heated with a few folks and said he was going to ignore some folks' replies. Don't remember if you were involved. I have to say, though, even though that discussion got kinda hot, he handled it well enough for the whole thing not to blow up in everybody's face. Doesn't seem like he holds ill wil towards anyone and just wanted to stop the back-n-forth.

No doubt we all agree enough about liking the G70 to be here talking about it. Of course, we can all get opinionated at times and don't always agree on everything about our cars. That's cool.

Just a heads up, anyone who's been looking for Front pads from Dynamic Friction. A couple places seem to have stock now, just ordered mine from RockAuto. PN 1552-2145-00
