Brakes Brake Upgrade Discussion (Discs / Pads / ... )

Need some advice.

Can anyone answer this query with mechanical knowledge? If I wished to replace the rear discs & pads would I need this so-called SST (09581-2T100) when installing the brake calliper assembly to push the cylinder back into the calliper. Or could I simply use a Brake Calliper Rewind Tool.

Picture attached from the Hyundai technician manual. If I took my car to a ordinary garage after the warranty ends I doubt very much any garage servicing my brakes discs would have such a tool to hand they would simply use a Brake Calliper Rewind Tool, would they not. What are the dangers of using this rewind tool without the specified use of the SST (09581-2T100 as maybe without that device it would be impossible to get the cylinder back into the calliper to fit new pads and discs, as obviously Hyundai state this has to be used in order to release the pressure from the cylinder. Have i got it all wrong I really don’t know but maybe someone can answer this for me with a degree of competency to allay any fears of doing this job myself with very basic tools well enough of a ratchet set which I have used all my life never came across this before.

Any help would be very much appreciated.
 
More than likely but you can utilize a manual tool to collapse the piston and seperate the pads. There are all kinds and this is but a sample of them;

Ok folks I was reading this thread about buying genuine Hyundai front and rear brake pads now I downloaded the brake calliper technician manual, on there it says that genuine Hyundai pads come with a pad return springs, picture attached as these springs keep the pads from rubbing up against the rotor while moving thus preventing premature wear or slowing the car down.

There is a guy in a you tube video who does just this replace the discs and brake pads he even noted that there were no holes in the pads to accept this return spring so would that mean pads without this spring would cause excessive wear to the rotor while in use or more importantly cause the car to drag as the pads may well end up rubbing of the disc, the guy in the video ended up using some sort of fixing paste to hold the pad back but he noted this may nto work properly. So without these return springs would pads without these return springs would they be ok to use in our cars as Hyundai have designed our pads this way for a reason something which aftermarket pads don’t come with that accessory or the pads themselves do not have the holes to accept these retention springs.

Hyuandi manual even make a note stating NOTICE of the retention springs must be replaced. So repalcing aftermarket pads may invalidate warranty concerning the wheels discs ETC, ETC.

Just out of curiosity what price are the hyuandi original pads.

Please look at the attached pictures to see what I am talking about and please do comment.

I think I would throw caution to the wind and buy genuine original pads what would yoru thoughts be on that point.

The guys video with a link to the tech manual maybe he is a member on here if you are a shout out, he he he.

Cost? This would be your thread, sir:

https://n-cars.net/forums/threads/brakes-pads-prices-in-eu-countrys.4261/#post-68427

My thoughts? Stick with OEM. They're more than up to the task unless you're going to track it frequently. And then all your other concerns and worries just fly out the window ;).
 
I have bought new brake pads once and there where no return springs inside of boxes. There was only a tube of lube (Daikalub 528D) inside of front pads box. Oem brake pads (both front and rear ones) have holes for return spings. If there are 2-identical spings in front, rear ones are both different shape.
For replacement, we should order them separately.
Front return springs: both 58188-G8300
Rear return springs: 58288-C5100 and 58288-D4750

Borg & Beck has front brake pads for our cars and their pads have also these holes inside for return springs:
https://www.ebay.com/itm/FOR-HYUNDA...REMIUM-BORG-BECK-BRAKE-PADS-SET-/264502357102

I can see that 4 other companies have front brake pads in offer: ABS, Blue Print, Delphi and Herth+Buss. None of these kits include return springs.

Thank you very much for the reply was interesting to see that the Borg & Beck have the holes for the return spring. Very good sleuthing on your part and I very much appreciate the links will save a fortune on pads Borg & Beck have been in business for over 100 years so I’m sure their stuff is very good.

I was wondering if this too good to be true or trolling. I read that OEM break disc are charged at 200 euros per set/disc. Does is Brembo one even work or is it completly false?Screenshot_20200122-202618.jpgScreenshot_20200122-202618.jpg
 
Brake discs diameter is (non-perf / performance) 330/345 mm in front and 300/314 mm rear. The one shown above might then fit for the rear brakes of a non-perf i30N.

However, some weeks ago I was also looking for brembo brakes discs and according to their homepage, they actually produce discs matching the non-perf diameters but not the performance ones: https://www.bremboparts.com/europe/de/catalogue/hyundai-i30-pde-pd-pden-2-0-n/000128762-1

Good link - I'm only pulling information on the rear brake 314 (19" wheel) & 300 (18") - anyone see the front brake info?
 
Oh, my bad - they only have 300 and 314 mm discs, so for the rear brakes of non-perf and perf but not for the front ones yet.
 
Hi guys,

I'm trying to adapt some focus rs mk3 front calipers.My question is if someone has tryed other calipers.I'm sure that i'm not the only one trying to adapt some brembos
 
Some option bits for the VN just announced. The 4 pot monoblocs look interesting. Wonder if anyone is able to get dimensions for rim clearance?

Not sure if they are available to be bought separately or will have to be bought with a new car.....

https://www.hyundai.com/kr/ko/vehicles/veloster-n/n-performance-parts

Looks like Hyundai displayed a Veloster N with a full Alcon brake kit (front 6 pot; rear 4 pot) in SEMA. These seem to be the most promising so far

is there an actual reason or just a want? Just curious thats one of the things Hyundai has boasted about hard core (for the performance model) that the brakes are un killable
Hello. I know this is a bit late to be adding to this particular thread but I did a track day in my 2019 N two days ago and the brakes were fading quite badly after a few laps in each session I did. Not good when trying to slow down from 120mph into a sharp left hander. Any ideas? The car has 1300+ miles on the ODO.
 
Steering Rack changed uner warranty. But this hasn't changed my issue.

Its not until car gets warm that it makes the noise which is a creaking sound through the steering which can only be heared at low speed and when you go over uneven road or speed bumps. Can be heared when turning in to drive way.

Hyundai Dealer said it been a fault on all i30Ns which I can't really see as it would have been mentioned on here by now.
Yep. I had that issue, too. But wasn't too bothered about it but noticed after a track day that the noise has gone now. No idea what it was though.

If you'd actually read the 14 pages of this thread, you'd get a propper good idea of what to do...
I'd start by changing to better brake fluid and upgrade to braided brake lines. Once your pads are down, you could think about upgrading those as well but the stock ones are not that bad that you'd need to get rid of them right away.
 
Done several track days now. First with no mods, then with Braided lines, Castrol SRF Racing fluid and brake cooling ducts from Nexd.
Big difference in brake performance.
I've a set of Pagid RSL pads but I'm going to save them until the OEM's wear or I get more power.
