Hi.
I had a similar experience years ago with a Fiat, I think it was a 127.
Exactly like that, at a low speed, without braking hard, just a crack and it was gone.
Without any warning whatsoever.
The brake was definitely not stuck or difficult to operate.
It wasn't a modified brake or anything like that, but the original one.
After that, I just replaced the rotor and the brakes worked perfectly.
Back then, even though there was nothing visible, I suspected a casting defect.
Best regards, Frank.

Hi,

Head of Quality Assurance and. Bachelor of Engineering.

Does he hold two positions within the company, or was he simply unsure of how to highlight the fact that he's a highly accomplished graduate engineer who earned his degree from a vocational academy?

These are my favorites...

Ouch . In the first picture, I initially thought, 'Ah, a spacer.' Maybe I should really start wearing my glasses more often...

I find Zimmermann's response to be simply outrageous. That alone would make me consider talking to a lawyer. What he's saying about the one-sided burden is, in my opinion, complete nonsense. The brake caliper must not be biased to one side; even if the rotor looks good on the outside, there are essentially only two possibilities, in my opinion.

- Piston stuck or difficult to move , poor or no braking performance but consistent, both internally and externally.

- Saddle either stuck in the guides or difficult to move , resulting in a one-sided effect, but then no/poor effect on the outside , and corresponding differences in the load distribution inside and outside.

However, the appearance of the rotor on the outside is very good, therefore, in my opinion, the brake is fine. Furthermore, it's quite easy to check the function of the brake, even during disassembly and after installing new rotors. Also, linings as well.

Regarding the nonsense about corrosion, I'd rather not say anything, as the way it's phrased is already an outrageous insult!

Hi,

Why go to a lawyer? It costs money and takes a long time. If expert opinions need to be created, the whole process becomes quite complicated.

The arbitration board is likely the more appropriate contact person in this case. They will prepare an expert opinion and issue an arbitration ruling that is binding on the company in question (hopefully, Zimmermann is one of them).

As a Bachelor's degree graduate, you are legally obligated to include "(BA)" after your name, because otherwise, you would be implying that you have a higher degree. We were at least led to believe that...

BA = Bachelor's degree; that's the reason it's there.

BA = Bachelor; that is the reason why it is there.

Incorrect. It should be either 'Diplom-Ingenieur' or 'Bachelor's degree.'

The traditional, longer-form diploma programs are being phased out in favor of the Bachelor's/Master's system.

As Mephisto correctly pointed out, a 'Diplom-Ingenieur (BA)' is a graduate of a vocational academy.

Aha.

You never stop learning.

I also expected it to be a Bachelor of Engineering (B.Eng.). Well, one should have known that BA and Dipl.-Ing. are not used together.

Thank you.

hiho

The brake disc probably had a crack since the summer.

I had been in Trier the day before, and I was driving significantly above 180 km/h at times.

Okay, so when going down the Trierer Berg, something started clicking at the front (like a broken dust shield). At home, I disassembled everything, and after pushing the brake caliper back, the clicking disappeared, so it was probably just dirt or something. I also thoroughly checked the rotor for cracks, but found nothing. Then, on Sunday, I went for a ride, and after a test brake, it clicked again, and there was no braking effect.

You can do this 20 times in a row, and it always yields the same result. What's strange is that you can hear a slight squealing of the tires and also see a very faint black mark on the asphalt. Nevertheless, you don't hear or feel anything from the ABS at all! Furthermore, I'm surprised that it's the same with the Focus. So, I can't really believe it's a design flaw. On the other hand: From a security perspective, it's _FATAL_.

Hello,

'I had the same problem with my 74 kW car. It even happened to me twice, while I was driving on the highway at 180-200 km/h and had to brake sharply. The brake pedal sank about 3 cm during braking. I quickly took my foot off the pedal and put it back on, and everything was normal again. Also, I was never able to activate the ABS, not even at 100 km/h. Unless I simulated a panic braking situation, which would then trigger the brake assist system. Shortly after these two incidents on the highway, I started hearing a single 'tick' sound every time I braked, up to 60 km/h.' Since everything seemed to be in order with the brakes so far – meaning everything was tight, there were no error codes, etc. – I started looking for the problem.
While doing this, I noticed that the rear brake calipers had a considerable amount of play in their guides. That seemed strange to me. So, I checked the brake calipers on another vehicle with the same engine (74 kW), but manufactured in May 2005. Mine was manufactured in early 2004. Sure enough, the calipers on the newer model were fitted more securely. Therefore, I disassembled both sets of brakes and discovered that the brake caliper carriers had been changed in the newer model. Firstly, they are somehow thicker, and the two guide bolts are also different. In mine, the upper guide bolt had play in its housing, while the lower one was tight. In the one from 2005, it was the other way around. So, I went to the dealership and, sure enough, my brake caliper carriers were replaced with those from the 2005 model. I ordered two, installed them, and I'm very happy with the result. Firstly, that annoying 'tock' sound is gone, and secondly, I somehow have more brake pressure. You don't have to press the pedal as hard to get the brakes to engage. Also, the brake caliper sits firmly with normal play, just like it should. For me, it's a positive change, and I believe it's because the brake pads were somehow stuck on the old caliper bracket, preventing the full brake pressure from being transferred to the disc. Or the brake caliper got stuck in its guides...

The speech referred to the Polo 9N, not the 9N3.

Oh, the brake calipers were free for me -> because of the warranty!!!

Best regards, Christian.

Hi,

to ride that one last time.

Yes, that's correct, but that's not what I was getting at.

I find the phrase "Head of Quality Assurance and Dipl.-Ing." absolutely hilarious. "Dipl.-Ing." simply doesn't belong there.
If we're going to do something, let's do it right.

"Sincerely,"
Achim Kerstan, Dipl.-Ing. (Bachelor of Arts)
"Head of Quality Assurance"

But if Achim ( ) signed it by hand, then that's also out of place. It's quite funny how some people try to force their title into things (e.g., even in phone books) and end up making a complete mess of it. Less is sometimes more.

Bitte gib den Text an, den du übersetzt haben möchtest. That leaves the brake booster itself. Does anyone know from the parts specialists what differences VW/Audi uses here?

*warm-up*

I did some research: according to the records, all 9N Polo models have a 8.5" brake disc size, but for example, the G4 can have up to 10". This calculation already shows a 38% increase in thrust with the same vacuum pressure.

The description, in my opinion, leaves very little room for design flexibility regarding the maximum [value/size/etc.]. Provides support (during emergency braking).
My other systems that rely on vacuum pressure (especially the VTG system) show no abnormalities that would indicate insufficient vacuum pressure.

What is the potential range for increasing braking performance when using the SBB/BS material combination in parts with an ABE (General Operating Permit), roughly speaking?

Is it possible that the braking force stops increasing beyond a certain threshold, even though the tires are still rotating, due to increasing hydraulic pressure? I somehow have this feeling that when I do a really strong full stop, and then a very strong one, and then a super-duper strong one .

I'm familiar with this phenomenon from my experience with the Golf 3 TDI.

In all cases, original brake pads from were installed (at that time, they were from Jurid). The pads still had about 50% of their lining material remaining, but due to the significantly decreasing friction coefficient as the temperature increased, they were undrivable for me, and they started to vibrate, which indicates hardening. After switching to a house brand product, things were quiet until the point of wear and tear.

Pagid house brand?

@Teileklaus -- you were paying close attention

You're welcome.
Judging by your fuel consumption, could it be that the brake pads are glazing over because you're not braking enough? Or perhaps someone else is experiencing the problem of them wearing out quickly?
It's a balancing act when it comes to the requirements placed on SBB.
I removed the EBC Blackstuff pads because they "don't provide enough braking power when cold," and I barely noticed that they perform better when hot and can withstand the heat better. (The pads had a blue coating).
