Erfahrungsbericht ATE Ceramic Bremsbeläge | Posts 16+

Both are normal for me.

After removing the protective film, the lenses are clear with the described gray transfer film applied in a uniform and barely visible layer.

You can take it however you want... I don't like the way the surfaces of the discs appear to be moving in the pictures. Especially not the uneven wear, including the formation of grooves. But maybe someone can explain to me why that's supposed to be a good thing?!

That's what the windshields of new cars look like when they're first used. It's not pretty, but it goes away after about 1,000 kilometers.

So, the windows are new, but they still smell musty?

You now have a silver protective coating applied, which is specifically designed to be removed by braking. For the first few kilometers, it looks very noticeable, but even though it may appear otherwise, it completely disappears after a short period of use.

Aha, okay! Thank you for the explanation.

With Zimmermann or Jurid rotors, the .20 and J versions are also always initially coated, so that only the friction surface becomes bare relatively quickly. However, it doesn't produce a harsh, irritating sound. This effect quickly disappears once you start braking properly and don't let the harsh scraping noise distract you.
However, Rainer described a later stage characterized by significant wear on the disc.
There seems to be a problem with the alignment between the top plate and the disc.
Whenever possible, I prefer to buy both components from the same manufacturer, although Zimmermann also has boxes for Brembo parts available.
The high-carbon version, also from NK (but starting with 3 instead of 2), is more resistant, but primarily to deformation rather than wear.
When choosing between T4/5 and Sprinter vans, it's always best to go with the latter, even if they are more expensive. @ Rainer, you should try the EBC Greenstuff brake pads.

Hi, somehow Bolzer's disc image seems to fit more with a vehicle that has mild braking issues, rather than Rainer's statement about higher disc wear.

I tend to agree. There are rust marks on the front discs that correspond to the shape of the brake pads. These marks appear when the vehicle is parked with wet or salted discs, or when it is left standing for an extended period.
Normally, this would dissipate on the front brake discs, which doesn't seem to be happening in this case.

Hi!

Based on my experience, I can say that using acidic wheel cleaners when cleaning a vehicle can cause problems if the brake discs are not rinsed thoroughly and dried quickly afterward.

After approximately 40,000 km, my experience with the disc brakes has become similar to that of @Bolzer.
The braking performance is okay, but I have to say that it is noticeably lower than with the original brake pads. The brakes simply don't bite as aggressively anymore; it's like going back to the level of a small family car. However, the braking performance improves when the brakes are hot, which is something I can't quite understand.

"My vehicle also shows signs of poor braking performance and rust marks on the brake discs, although not as severe as with Bolzer's car. Since I live in a hilly area, I don't believe the problem is caused by excessive braking, but rather that the discs and pads are simply not compatible with each other."

During the next brake service, the pads will be replaced with standard ones again. While the pads wear down very little, the brake disc is now wearing down (it was newly installed along with the pads).
That's not worth it to me, considering the reduced dirt on the rims.

As of the current state of the art, this seems to be the only correct way.

Hi,

"I don't want to defend these parts at all costs, but I've had them on the back for 30,000 km and one winter. You can still see the grooves from the initial machining, which appeared under the protective coating from the beginning (see pictures). The discs show no signs of thickness wear, and there is no noticeable burr."

"I've only put about 1500km on them so far, so they still look good. The braking performance from maximum speed isn't great; there's noticeable fading. However, that might be because this was the first time I've braked hard from that speed. I'll keep an eye on it. From normal driving speeds, the effect is barely noticeable compared to the original brakes."

Here's what my brake discs look like after approximately 30,000 kilometers.

Hmm. Not quite as good, but in my opinion, not yet concerning.
Was was that, based on the amount of time it had been there (indicated by the dried droplets)?

At MT, images of VW-Original windshields have sometimes been shown, which looked significantly more corrugated.

If the high-speed cornering still feels good, I'll be happy. The constant wheel scrubbing was really starting to get on my nerves. It's a relief that it's gone now.

My uncle has his own workshop and has been using Ceramic coating almost exclusively on his customers' vehicles ever since it became available. So far, he hasn't received a single complaint. We also haven't had any problems with it on two C-Class cars, a G IV, and a Touran in the family.

No, I even went up and down the winding road twice to brake properly. It was even worse before.

Quote:

If the high-speed fading stops, I will be satisfied.

"With my car, the brakes initially only provide a little bit of stopping power, but the more they heat up, the better they work. However, I don't drive the car like a Formula 1 car all the time, so it's not really that beneficial..."

Best regards, Rainer.

Wow...

It's strange how people are having such different experiences with these parts. It's clear that ATE still has some work to do.
