G70 aftermarket brake pads

[PB716]

For what it's worth, I didn't go through a proper bedding process when installing mine.

Just drove it like normal, and the abrasive nature of the metallics cleaned up the rotors pretty quickly.

Yea im probably only 15 miles in and I already noticed the rotors look cleaner. They feel a lot better but that's mostly due to the fact that the rears were in need of replacement to begin with. The fronts im hoping to fix the shimmy. But I will definitely let yall know.

Just installed my dynamic friction rears.

May I ask how you dealt with the electric parking brake issue? I was under the impression you need a service tool to be able to remove the rear pads without trouble, but curious if that's necessary. Thank you.

I just pushed them back normal. It didn't give me any trouble.

Good to know. I recently did the rear brakes on my wife's CX-5 and had to enter a special service mode to allow the brake pistons to be pushed back in. Luckily I watched some You Tube videos before just trying to force them back in.

So unfortunately it looks like the front pads I ordered are incorrect. These are the ones I had to type in the part number to find and they're definitely not right. Can't find the right DFC pads anywhere in stock so now I'm looking for a more budget friendly alternative to the euro pads.

Did you look under Kia Stinger? I see the front pads there.

I didnt see any semi metallic fronts. If you do post the part number and/or a screenshot for me please

Ah you're right. Was looking at the ceramics. Sorry!

Did you look at the EBC Yellow? Probably cheaper than the Euro pads.

I was taking a look at those. They seem to be a good option. I'm not in a huge rush bc the front pads are only a few thousand miles old so I'll probably hold off for a while and see if I can get the Dynamic friction pads, if not those are seeming to be a good option also.

If you can put up with the brake vibration that long. It drove me crazy.

I am glad I saw your post as I am about to replace the pads on my wife's 2016 CX9 that probably has the same system

 

[Husky]

I would imagine. Just Google it, there's some good videos that show you how to enter Service Mode. It's not hard but I forget the details.

Do you have experience with the Yellow Stuff pads in the winter?

I hear they need a little bit of warm up and then work excellently. My commute is pretty long so I think I’ll be alright but I’ll report back if it becomes dangerous in the winter

I just perused through all 15 pages of this thread and I did not see anybody post pictures that show the core reason why a lot of us are changing brake pads. Well, here goes. Here is what my Stinger brake rotor looks like now, after doing the Brembo retrofit about 1-1/2yrs ago. Other than a couple of AutoX weekends (in Feb and March, so cold/cool weather), I don't really push the car hard in everyday driving. Still, the pad material transfer is very clearly visible on the rotor surface. I'm putting up with this, mostly because the deposition is fairly even all around the rotors, so I don't get any pulsation. That said, whenever I push the pedal a bit harder, I could feel - and hear - the grittiness that comes from the brake pads interacting with all the small deposits on the discs. The brake pads that came on these Brembo calipers are stock Stinger GT and they were in pretty good shape, so I took a chance on them. And I'm generally happy I will probably end up getting a couple of years of use out of them, before changing out to better pads.

The rotors are perfectly fine. Other than the pad material deposit on them, the surface is almost glass smooth with no grooves. I see no reason to change them out with the brake pad change. Probably don't even need to have them turned. I'll measure them with a caliper when the time comes, and that will tell me what need done.

Have not decided yet which pads I'll go with. Semi-metallic for sure. Probably EBC, since I've used their motorcycle brake pads and like them a lot.




Now then, below are the 2021 G70 6MT. As many of you know, the 6MT version reportedly came with EuroSport pads that do not suffer from the pad material transfer problem. They also work much better at sustained high braking effort and temperature. As you can see below, mine did not disappoint. This is after 1yr of driving and 2 AutoX weekends (June & July), with my son and I both running in the same Heat, so the brakes got plenty toasty. There is absolutely none of the deposits that pepper the Stinger brake rotors above. There are some deposits, in the form of lines that show where the brake pad sat static, which is actually fairly normal and typically wear themselves out with use. If this isn't the case, you would not see just a couple of lines, you would see a whole lot of them.

The downside, of course, is much more brake dust, compared to the Stinger. This pic below is about 120 miles after last car wash, and the rims are already covered with a film of brake dust. IMO, it's a fair compromise with semi-metallic pads. I make a point of picking aftermarket rims that are easy to clean, for this very reason.

Lots of good stuff here. Thanks man

great summary, Volfy. interestingly, your experience closely matches mine, with my 6MT, and my bro-in-law with his Stinger. just last week he had his rotors replaced under warranty for "warping", although after i counseled him he clarified with the dealer this was in fact due to pad transfer. i told him to speak to the dealer about swinging a deal for the Euro pads but no dice. they replaced the rotors, said his stock ceramic pads had tons of life, and sent him on his way. so, i told him to expect the same issue down the road, at which point he'll know for certain the cause.

my 6MT rotors look just like yours - smooth as glass, can almost see my reflection. my wheels stay clean for maybe 1 commute. but since mine are the dark Sport rims, the dust is well concealed and only i can really tell. after a week the wheels simply look more like a matte finish...until i touch them.

Genesis/Kia are really shooting themselves in the foot on this one. The problem is so obvious and well understood by most of us who frequent G70/Stinger forums and groups. Why they keep blaming it on warped rotors is beyond me. It just reinforces the misinformation on those who want to believe otherwise. To the point where it isn't uncommon to hear folks trash-talk the G70/Stingers as having "fake Brembos". No doubt the aftermarketeers are all too happy to fan the flame to help sell drilled/slotted rotors.

FWIW, I've been keeping a close eye on the Stinger brakes since the Brembo install, knowing that problems are likely to manifest at any time. I actually just started noticing the deposition this Summer. Not sure if it's the Summer heat that triggered it, or the couple of AutoX weekend earlier this year. In any case, once they started to appear, it just seem to get worse. I tried a few heavy applications (panic stop style stomps), either cold or warm rotors, to see if I can force the pads to scrub them off. No dice. They do seem to come off with stainless steel wool and lots of elbows grease, but no freaking way I'm doing that manually on all 8 sides of the 4 rotors. Even with power tools, it'll still require removal of the rotors... only for the deposition to happen all over again anyway. What's the point?

I'm leaving the Stinger pads on for now, actually more for the academic exercise of seeing how bad it'll get. At least, before I resume AutoXing the Stinger in the Fall, once my son goes back to school with the G70.

It's definitely a lot of work to scrub them off. I cleaned off the front rotors about 2 weeks ago and have yet to get to the rear rotors. I'm dreading it.

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.
