G70 aftermarket brake pads

[thatjawncrazy]

Guys, I had my 100% stock 2022 G70 3.3 up in the mountains yesterday for some spirited driving. Temps were in the 40s to low 50s. I was coming down a curvy mountain road (fast) when I started to feel a light shudder when applying the brakes. It continued for a bit and I thought maybe I had bent a rim or a tire was going flat but then I started to smell the unmistakable odor of brake pads cooking. I slowed down and tried not to use my brakes for a few miles thinking that I just overheated them but I didn't feel comfortable riding fast the rest of the day. I did use the brakes of course on the 60 mile return ride and I didn't notice any shudder or loss of braking.

I am thinking the pads are shot at 8000 miles - that is total miles on the car. I have done spirited mountain riding numerous times before with this car and this is the first time I experienced this.

Should I change the pads? Should I go with a different pad this time given that I like to drive aggressively?

Suggestions?

Thanks.

Rotor warp?

I have an issue where whenever im braking a little hard the car starts to judder a bit and the wheel vibrates back and forth a good bit. Ive noticed it gets worse when the brakes are warm but regardless, it doesnt do it under light braking or under very hard braking. Anyone know what that might be?

G80 Brake Pulsation Campaign

Hello everyone, this feels a bit like deja vu as my 2015 Genesis had the same problems. Are you familiar with this campaign: TPP, 16-01-043-Genesis G80 Brake Pulsation? I ask, because I picked up a beautiful G80 Ultimate two days ago and have what I feel is warped rotors, particularly at high...

Brake Vibration?

I just picked up a 2019 G70 AWD Design, after the brakes warm up from driving there is really bad brake shudder felt in the steering wheel. I tried the bedding suggestion to try and clean up the rotors but it hasn't worked. I see what looks like blue streaks in the front rotors but the rears...

Brake Rotor upgrade/replacement recommendations?

Same issue, machined once, vibration came back. 21,000km. Going to bring this up next service. I heard one of the brake pad part numbers is discontinued, presumably related to this issue. Can anyone confirm the standard brake pads are discountinued? Totally agree. MY front rotors have been...

Welcome. Well documented issue. I replaced mine with R1 concepts pads and have never had an issue since.

Thanks - did you replace the pads on all 4 wheels or just the fronts?

Also, I see several different options (Optimum, ceramic, semi-metallic) for pads from R1 - which ones did you go with?

No problem! Maybe you can see them in this picture but I got the R1 slotted/drilled rotors as well. Optimum on all 4 wheels for street driving yet they seem to hold up really well to high speed braking etc. Don't even waste your time at the dealer getting your rotors turned - the stock pads are the issue.

On descend on the mountain road, did you downshift and use the engine to slow down? Or did you ride the brakes coming down?

If you were smelling hot brakes, my guess is you were riding on the brakes more than you should. That is bad juju regardless of what brake pads you use.

We vacation in Colorado quite often, and coming down from the mountains, regardless of which vehicle we took, I would be shifting gears to regulate speed far more using the brakes. Typically, I only touch the brake pedal just before reaching the switch back to set the speed for the turn.

If you read my post I said it is the first time it has happened to me since I bought the car. I do most of my spirited riding in the mountains. In fact, I have been down that very same mountain numerous times at the same or higher speeds with the G70.

I don't ride my brakes and I know how to brake/downshift properly. I even asked my buddy behind me in his 911 Carrera 4s if he saw me on the brakes a lot and he said no - all he saw was my normal brake jab before the apex. He rides with me all the time and he would have noticed it.

I just took a look at the pads (without taking the wheel off) and they appear to still have a lot of visible material left.

Will drive with them around town for a bit to see if I can notice anything different. May wind up swapping pads as suggested.

That's good to hear. Take a close look at all 4 of your brake rotors. They will tell you if you've got brake pad material transfer, and/or there is evidence of hot-spotting. That will give you a clear indicator of what you might consider for upgrades - whether it is brake pads only, or if rotors need changed too.

I posted pics of what a good clean brake rotor should look like, and what typical stock brake pad material transfer looks like, here: G70 aftermarket brake pads

Bear in mind that if the rotors are allowed to overheat with pad material transfer, it could cause heat spotting. Once that occurs, rotor change becomes a necessity. Take a look at what one looks like. EBC RP-X™-Equipped Fiesta Racer Continues ST-XR Championship Success

Here's what a healthy rotor should look like, once bedded in properly to new pads. The bluish/yellowish hues means the rotor has been heated up to temp evenly and there is a proper amount (very thin layer) of pad material lay-down on the rotor surface. This is what yields best frictional characteristics and optimum brake performance. (original post earlier this thread: G70 aftermarket brake pads)

after hearing WJH has plenty of pad meat left, this is likely the uneven pad deposit issue that has been widely discussed on this and other forums.

 

[WilcoJunoHotel]

OK, I read through all the other posts about the pad deposit issue and it sounds like that might be what happened. I will probably order a set of the non-ceramic EBC or R1 pads to try on the fronts. Might get them on over the holidays.

Thanks for the replies.

Just picked up my car last week (2020 3.3T AWD) and immediately noticed the terrible brake judder. Car has 30k miles on it.

I took advantage of some Black Friday deals and ordered a set of R1 Concepts rotors (Geomet blanks) and EBC Red Stuff pads for all 4 corners - looking forward to getting the vibration issues resolved!

Since the car is still under warranty, I'd have brought it to dealer service with that problem. From what most owners have reported, dealer would most likely change out the rotors and keep the old pads. It's the wrong way to fix the problem, as we all know, but you'd have gotten a set of new rotors for free. Then buy the aftermarket pads of your choice

In my experience, they make you go through the inconvenience of turning them first. You get new rotors when that doesn't work, so it may require two visits. It's all such a stupid waste of time, but you're right, you will eventually get new rotors.

 

[WilcoJunoHotel]

Here are a couple of photos of my front rotors. The one pic shows pad thickness.

Rode about 120 miles since and the brakes seems fine: No grabbing, no shudder, no vibration.

Will probably order a set of aftermarket pads and if/when it happens again, I will change them.

Pad deposit is usually the culprit of shuddering, actual 'warping' as some state is highly unlikely and it is usually one of the causes from this link on hot spots. Often these deposits will cure themselves with continued use, but sometime having the rotor turned on a pro-cut lathe is necessary.

That rotor actually looks pretty clean. I don't see the typical pad material deposit pattern. There is visible wear but hard to tell without putting a caliper on it. As long as you are not anywhere close to the wear limit of 28.4mm, the rotor is serviceable.

I wouldn't mind if they do a good job turning the stock rotors. I've mentioned previously that in some ways I actually prefer turned stock rotors to new ones of questionable quality. That is... if I know the history of the stock rotors and they have not been abused or hot-spotted.

Hey gang, are the pads on non-Brembo brakes okay? Just curious. My 2023 2.0T Sport Prestige has the regular brakes, and just want to know if those pads are fine, when it's time to replace them. Car is not driven hard. But curious since it came with summer tires on the same black 19" wheels as the 3.3T SP. Thank you.

 

[canucklehead604]

^ your Sport Prestige came with 19" sport wheels but non sport brakes? that seems like an unusual combo but i guess packaging has changed a bunch over the model years.

i'd guess standard sliding-caliper brakes have ceramic pads, probably a safe bet. i don't think this thread is exclusive to teh sport brake trims so i'm sure you'll find feedback for your brake setup. perhaps the standard brakes/ceramic pads do better than the sport/ceramic pads but i doubt it.

 

[JCtx]

Yeah, it looks identical to the 2022 3.3T Sport Prestige I had to return on the outside, except the Brembos and dual-exhaust. Wish the tires were A/S, but are exactly the same PS4 summer tires (same sizes too) and wheels on the 3.3T. The brakes are the cheapo ones on all other trims, but was curious what kind of pads it has. Not sure which rotors it has either, but I assume are smaller than the 3.3T.

Do you have a part number for the red stuff pads? Where did you get the pads for all 4 wheels? I'm only finding front pads.

As a footnote to my previous post about the brake pedal shudder and then the brake smell .......... I have put about 200 miles on the car since this happened and it has not occurred again. Brakes seem fine, in fact, in traffic they are actually doing better and I am not getting that hard 1st gear downshift when slowing down (around 20-15 mph) that has been present on the car since I bought it with 2000 miles on it. I am guessing that the pad build up was causing some jerky braking that was affecting the transmission sensors. It is very smooth now - I can slowly approach a traffic stop and not notice the transmission downshift at all. I had read the other threads with posts about getting the TCU reset and thought that was what needed to be done to mine but apparently the brake pad buildup was so bad it was causing this issue too.

Very odd. I have owned a lot of cars & motorcycles over the years and this is a first for me. Still might change the pads but will hold off for a while to see if the build up happens again.
