FAQ: Vibration under braking: warped rotors? NO!

[turboAWD]

Just curious - I've seen the Euro pads mentioned here, and some have gone that route. Are they the same as the Australian pads, or different yet again? What about KDM spec pads?

Thank you. I had a quick look at a website that sells aftermarket parts for the Kia and Hyundai. there are several pads and brake brands, and various price range. I have no idea what I need as I never had to change pads or rotor in any car I owned. What should I get? Would be possible to get informations from some experienced member of this forum please?

I asked hoping there was some news. I haven't been checking the forum for a long time amd after resurfacing the rotors I was hoping to have done with this issue. Apparently not. I have a service scheduled for next week and I wanted to get info before (very limited time to check the forum). Sorry if I bothered people with same questions. I am just not an expert and don't want to make wrong decisions.
Thanks for the link to the search page.

I got Gyrodisc pads. Working great. I also put on new stock front rotors. Stoptech and Cquence are supposed to be good too. If your rotors are too bogeyed up new ones are just over $200 if you buy them online. They key is different pads and rotors that are don't have melted material and cementite in them.

Sorry for being curt. Must have been the hour after a long day (it was past my bedtime; I should probably knock this off before then. ).

Don't worry, u were not. I have another question though. Let's say I am going to go for aftermarket brakes (model and type are irrelevant at this time), where should I go to have them fit? to the kia dealer or to a shop? in case of the latter, is there a recommended one?
Sorry, I know I asked many questions, I just want to get to the bottom of this thing as fast as possible

Any competent mechanic can fit brake rotors and pads. Choose someone you trust - independent workshop, dealership, the biggest difference is likely to be price.

For what it's worth, doing it yourself is far from challenging if you're even remotely mechanically minded - but there is the fact that your brakes are what prevents you from sudden unintended deceleration (stopping suddenly when hitting something solid), so some people just prefer to let a qualified mechanic do it.

 

[Manaz]

Are the rotors warped or not?

Nope. It is at best a misnomer, at worst a lie to trick people into paying for services that don't actually fix the root cause of the issue.

People like Carrol Smith (ran race teams) say rotors just don't warp. Material engineers say rotors don't warp - the temperatures reached even during the hardest braking on a racetrack are simply not high enough to physically change the shape of a brake rotor.

The following thread has lots of good info.

I would use either my "wheel guys" (I trust them) or the dealership I bought my car from. Either would suit my situation. I would not do the work myself: I've never worked on my own cars much: I remember replacing a fuel filter in our old Chevy Impala years ago, that's about the extent of my experience.

I second this, I have them and they have been very good.

Haha hopefully soon
The part number is now available just waiting on the actual item to be ready

Instead of making a new thread I decided to hop into this one. I am having issues with the brakes shuddering after driving for a longer period of time, stopping from a higher speed (over 60mph) or down a hill. I am driving to NY from NC in November and I would like this issue solved by then. I was looking on K8stinger store for pads and there does seem to be some to purchase. I am however not mechanically inclined and was curious about that listing. The listing says it is a set of 2 front pads. Now is there a difference in pads between the rear and the front? I know there is a difference in size and piston configuration. I was going to buy these pads but I wasn't sure if it is known that the front pads are what is causing the shuddering? I would rather have matching pads all the way around and not mix and match. I have posted the listing for the pads. I am just looking for a solution to the shuddering. I would post the listing but i'm not able to currently as it is restricted. Thank you.

This I know from my reading: shudder felt through the steering wheel is front discs with deposits; shuddering felt through your seat is deposits on the rear discs.

OEM pads have the same composition front and rear but are different sizes. So far, only front aftermarket pads have been available; the rear aftermarket pads are only now coming available. But if you're not feeling shudder through your seat, your rear brakes are fine.

 

[itguy61]

Also realize that the vast majority of braking power and thus strain on the brakes is on the front brakes.

 

[Ulikefishsticks]

Thanks for the info, i'm surprised it has taken so long for pads to become available for both the front and rears. Now the deposits are on the rotors themselves so these front pads won't alleviate the shuddering unless I get the rotors turned also correct? Then i'm assuming these ceramic pads will still require the proper bed in process after I get the rotors turned? I'm still trying to find a stretch of road where I can do this at and not have issues. I am pretty sure I feel the majority of the shaking through the steering wheel. Should I go through the dealership about replacing the rotors with a set I have and getting rotors turned or is this something not covered by warranty because I am not technically using OEM pads anymore? Thank you for the replies.

You will need to bed in the new pads. I would start there. They are much cheaper than rotors and bedding them in might remove the deposits on your rotors.

I bedded my pads in on the hwy late at night. That allowed me to accelerate, brake, and coast for long stretches without having to worry about traffic or stopping.

Just buy the new front pads, install them, and then "bed" the new pads.

The bedding process will remove the old deposits and you shall be good to go.
