Brake pads

[Jerome92]

Mmm honestly no, so far they are perfect. I guess you have tried cleaning the hub surface before reinstalling the disc?
You could try with a new sets of discs to see if it’s actually their fault or something else

 

[Jerome92]

Only strange thing to report for me is sometimes a loud “bang” from the rear axle when braking hard. Something similar to the last video from Misha on the Ring I think. I don’t care to much about it as nothing seems out of order, possibly a bushing of the rear axle that doesn’t like the stress or an aggressive engagement of the ABS?

Yes, cleaned everything, gonna try with new rotors after summer.

Hmm never had it happen to me but I read about it. Im still on factory fitted rear rotors and pads, maybe aftermarket pads produce that sound.

I’ve got aftermarket pads and rotors for my rear but haven’t fitted them yet. However, I’ve worked on the rear suspension when I fitted my Whiteline rear sway bar and I can’t see any reason that heavy braking should cause a bang sound.

 

[Jerome92]

I had it since new, very rare though

Next up will be Project Mu HC+ for the front which some people report as good dual street/track pads.

So I slightly changed plans. I’ve seen people on GR Corolla forums sometimes order parts (including brake pads) directly from Japan as some brands are much cheaper there. I’ve beginning hunting for parts for the i20N and found that on RHDJapan they have Endless pads for a fraction of their European prices: https://www.rhdjapan.com/search/eng.../hyundai_i20n/car/hyundai/cpre/1/incldisc/uni
I’ve ordered a set of MX72+ and will report back on the delivery experience and on custom costs. They also have more aggressive pads for the track available.

As the pads won’t arrive on time for my last track days of the year I’ve pulled the trigger on a set of SDT RS-55 coupled with Tarox F2000:

These pads have a not too high friction coefficient of 0.51 and are rated up to 700C which should be an improvement over the Street+: https://sdtbrakes.com/en/blog/notic...ng-compound-performance-safety-and-durability

As I was checking out the Tarox catalogue I’ve also had a look at their BBK, very expensive but the 8 pistons caliper seems pretty impressive. The disc size is an unusual 345x26, but this combined with a narrow caliper means the kit slots into the stock rims virtually without the need of spacers (I’ve tried with their template and I reckon a small 3mm slip on spacer could do the job).

Corsa pads have not appeared yet.

Search for firtech, a member here who tracks often has tested many brands but he ended up with them and he was really happy. So i strongly believe you should use the previous experience as we all try to do. you can order from a place in Italy. Search to find the afforementioned post.

You mean Fritech? Yeah, I know them as in fact I have posted in May '24: https://n-cars.net/forums/threads/brake-pads.6851/post-159821 They have been the first aftermarket pads I have tried (I am Italian).

Last year I have run their "R60" compound, they brake very well, but they lasted only 3 track days and were very aggressive on the discs (I had to change the stock discs as well), not considering they were also pretty damn noisy on the street. This spring I tried the less aggressive "R40" compound (with Zimmermann discs) as recommended by the dealer, but I did not like them at all. They smelled of burnt, their braking force was quite bad (I had one track day on stock pads when I was waiting for the R40 to arrive and I would say the stock ones were actually better). I had a very experienced driver test my car and he did not approve of the pads. I then went to the Pagid Street+ which are miles better for anything but long-ish track sessions (they just consume too fast), and that's why my hunt for a dual track-street pads continues.

I think the Fritech R60 are in the same club as EBC RP-X, SDT RT-66: aggressive pads, with strong bite, but eating the discs and noisy on the street. I am looking for something more civil as swapping pads back and forth on the floating calipers is a bit of a pain. For my taste, slightly lower mu is also better for the track: better modulation and less heat generation

The wear sensor breaks when it gives a warning and must always be replaced or bypassed to cancel it.

Is this the case that it will always break when the pads need replacing? as some people seem to say they have managed to replace just the pads and not had to trick the sensor by shorting it

If you got the warning on the dash you need to replace the sensor because it gets destroyed when it goes off. If you replace the pads before the warning then you can reuse it

It is a wire encased in plastic. As the pad wears and gets thinner it allows the plastic to get worn away and eventually the wire is also worn through. This open circuit triggers the warning. So if the warning has gone off, then the sensor is used up.
It looks very like the Brembo one to me, but it wouldn't have the right connector on the end. If you are happy cut and join wires you could probably save a fair bit over the Hyundai dealer one.

Thanks guys much appreciated

I can offer a first feedback from street and track use of the SDT RS-55: overall very satisfied. They work well from cold and have held up the track use very well. They had some fading during the bedding in process but then stayed consistent. Wear has also been much better than the Pagid Street+.
I would recommend them as a good dual street-track pad, quite a bit cheaper than the Pagid too. The only downside is that, despite having NVH shims, they do squeal a bit when coming to a stop, although much better than say the Fritech R60.

As for the Tarox discs, early days to say but they have held up very well the first track day despite pushing very hard. Barely any wear at all. The grooves do collect some dust though and they tend to give a very slight vibration (actually more a sound than a proper vibration) when first going on the brake pedal at high speed.

where can someone buy the SDT RS-55? I am from Greece and we have not this brake pads down here. Last but not least, hoe much a front pair costs?

Directly from their website.
I can add that they also stopped squealing since the track day I did with them and it's already been several hundred kms.

In other news, my MX72+ have been finally shipped from Japan. For now cost of pads and shipping has been 229€, let's see what import fees I will have to pay, but for now not bad considering that in this moment you can find them on AT-RS.de for 558€!

 

[Teapea]

Somewhat off topic for this, but I have a problem where when it's raining and sub 10C, the OEM brakes don't bite right away. Has anyone else had this and how have you sorted it out? This being with just normal driving.

 

[i_twenty_N]

It is normal, at first you have to bring some heat into the material. Otherwise drive even more gentle to avoid the need of a better breaking performance.

Hello forum,

Newbie question from a fairly novice i20N owner here

It's time to replace brake pads all round on the car and i've narrowed it down to three options:

EBC Yellowstuff - DP42500R (front) & DP43154R (rear)

EBC Bluestuff - DP52500NDX (front) & DP53154NDX (rear)

Brembo Extra - (can't find part number for now)

What do people generally feel about these pads and if they're worth fitting?

I'm looking for something better than the OEM pads but don't need racing / track spec

I will be doing discs soon as well so any recommendations for which discs to pair with these pads are appreciated too

Cheers!

 

[Jerome92]

I haven’t seen the Brembo Xtra listed for the i20N, neither on the official website nor on any distributor catalogue. I suspect they just don’t exist (yet) for our car. Brembo is a bit vague with details, reading through the lines they seem similar to Yellowstuff. Maybe someone has tested them on other cars and can shed some light on them…

 

[jonowev]

I've been doing a bit more research and heard at the EBC Yellowstuff / Bluestuff produce a lot of dust as well as wearing the discs quicker than a lot of other pads. Think they are better suited for short busts of hard driving / track driving and not ideal for everyday use.

Anyone got a reccommendation for ceramic pads which will fit the i20N standard calipers? Open to pretty much all suggestions provided they are good solid, high-quality pad
