I am getting ready to do my rotors and pads, have been running euro floating rotors for 70K miles now and I think they need to be replaced, regular street driving since new with few track days? There is a small lip on the edge so i have to properly measure them, but what is the recommended rotor plus what pad to perform well at initial bite like OEM ?

I've considered carbotech 1521 but they want over 400$ for a set of front and back! I get OEM pads from dealers for about 100$ but hate the dust, so looking for an alternative.

I've read about Akebono but not sure which model number Akebono EUR681 Front and Akebono EUR683 Rear.
Now I had used Akebono before but I don't think it was the EURO version and HATE IT, no initial bite till they got hot.

What other pad to have a good initial bite would you recommend with less dusting than OEM?

P.s. What's the allowed rotor wear in MM?

Does anyone use ceika big brake kit? For about 1200 6piston front with rotor and pads.

Thank you.

A lot of guys really seem to like the Akebono's, never tried them. I'm running Hawks red on my 545 and Hawks yellow on my M6. Will switch the 545 to yellows first chance I get. both brake great but yellow much less dust. feel like there was no change in initial bite from factory pads on the M6. Call em up and ask them. they answer the phone.

The Akebono Euro Ceramic formulation is little changed from the earlier versions...meaning still low dust, and still poor initial cold bite.

One new problem with them on the E39 540 application and X5 application, you can get some knocking noises during brake application, both in forward and sometimes rear application of brakes. I tried a couple sets, and even replaced my calipers and carriers with brand new ATE parts ($$$!)...still clunking. Bought ATE Ceramic pads, no clunk. Better initial cold bite too...but a bit more dust than Akebono, go figure. Not sure why the pads could cause a clunk/knock, never had issues with Akebono until recently. Possibly a dimensional issue with the backing plates?

I hear Hawk Ceramic pads are really good compromise between low dust and performance...but pricy.

I've had the akebono's and hated the cold bite. Low dust was great though, and on multiple stops, once hot, they were decent, but that is not normal street driving. Couldn't wait to remove them from the car. My next set was Carbotech 1521's. They were pretty excellent overall. Good cold bite, lower dust, but not as low dust as the ake's. The rears, had a bit of a squeal once in a while, but otherwise no issues. They wore out this year so I needed another set. I looked at the price and was shocked at the price increase. I ended up getting TRW Ultra's this time. https://www.fcpeuro.com/products/bmw-brake-pad-set-trw-txc0681#description
They are pretty damn close, but not quite as good as the 1521's. Good cold bite, with dust maybe a little less than the 1521's. Price is nice. I've got maybe 5k miles on them now and am pleased with my choice. Very quiet too. Nice backing plate and packet of good lube in the pack. I use Centric Premium High Carbon rotors.

So +1 on TRW ceramic. I haven't tried them yet, but my local BMW specialist DUDMD Tuning has told me they have been using them on a lot of customer cars with excellent feedback. They like them a lot.

I've been using akebono euro pads for quite some time.
Saved me great money as I don't have to purchase wheel cleaners anymore.
Just some diluted APC and soft teflon brush. CLEAN

As for the brake feel. Yes they are still horrible. I actually quite like it as I can control it so the body doesn't jolt at all when coming to a stop. (Try this with your normal pads. You will find it pretty hard.)
Please keep us updated with the TRW and carbotech.
TRW sure doesn't feel very ceramic-y with the color. But it might be something different.

Cheers,
Gabe

I'm thinking through this decision right now since my car will need brakes soon. I currently have Hawk HPSes on it and the braking force is good once you lay into the pedal. The initial bite is not as good as stock Textar and the dust is about the same. However, they squeal like a damn train (especially when it's cold out) and nothing I've tried to fix it has worked, so they can **** right off.

I recently put Carbotech 1521s on the front of my E38 in conjunction with the 750 front caliper retrofit. I'd describe them as adequate. With the exception of low dust, they didn't blow me away in any metric. The initial bite is all right and the braking force is linear. I don't have the best gut feeling about them, so I may try something else on the M5.

Ok.. not affiliated in any possible way. If anyone from gyeon is looking on this forum. Please contact me privately so I can get paid lol

Not promoting anything. But my recommendation is to go with stock or decent pads like OE or TRW.
Having said that. Coat your wheels. Gyeon Q2 Rim would be my choice.
Previously used on my other car with extremely hard to clean wheels.
I cleaned the wheels extensively. Used multiple bottles of all sort of cleaners then applied Q2 Rim.

I've seen some great improvement in terms of cleaning. The dust doesn't stick to the wheels. Just pressure washing removes most of the grime.

Cheers,
Gabe

I wanted to share a really simple way of installing INPA!

I downloaded hacked version today from HERE. All you need is a Windows laptop, cable and you will have all the functions including ABS activation. Or you can buy this UNIT

I have the ABS pump from ADAM and will proceed with the install.

I measured my EURO floating rotors after about 60-70K miles of use and they are still in good shape,

FRONT RIGHT - 38.1MM
FRONT LEFT - 31.75MM
REAR - 19.05MM around

I'm not sure if I should replace them with Zimmerman rotors ( none floating :( unfortunately ) as they came in today from FCP Euro ( lifetime warranty ). Or do another set of OEM pads on the current rotors and save a headache. I think the reason why they are still thick it's because I used OEM pads and were really easy on the brakes, besides having weak grabbing force due to a suspected faulty ABS pump.

I activated the solenoids today and one of them sounded very weak ( explains thicker right rotor ). I will report back.

I did find floating rotors in Australia! Will check with the dealer tomorrow if they have any floters.

Interesting, never heard of Gyeon. I used Meguars NTX Generation Wax 2.0 summer of 2020 on 3 different cars rims including daily driver and it still seems to be working good.

You should definitely try it out. Though, keep in mind that the Meguiars wax you are using is a bit different from Gyeon rims.
Gyeon Rims is more of a coating that should last about 7~8 months (in my experience).
Yet, having said that, be prepared for some DEEP cleaning. It's really annoying sometimes.

Pad choices are always a hot debate issue.
The question comes down to the following as you can't have both

Cold initial bite (Carbon is the trick here, hence the dirt issue)
Street Performance when warmed up

I used the Cool Carbon Pads on my M5 with great results. With some aftermarket pads the cold bite is so bad you might as well open the door and drag your feet to slow the car down on the 1-4 slow stops. Metallic pads are usually the worse at cold bite. This is not true with most Ceramic pads. The TRW Euro Ceramics are great too. I have used Centric pads and rotors with success. For Euro spec floaters I have to leverage BMW & MINI parts styling tuning new and used parts - Schmiedmann - New parts to get the right rotors as sources in the USA proved unresponsive.

On a completely different note
That rotor is so pretty in your post.
I'm sad that ATE doesn't make this rotor for our cars.
