Experience with Powerdisk and JURID brake pads | Posts 16+

After 20,000 kilometers with the Powerdisk brake rotor, a more or less pronounced brake shudder can be felt, caused by the ferrodo brake pads glazing over the grooves.

Another vehicle with original ATE brake pads does not have this problem.

Always use the Powerdisc together with the original brake pads.

I only have these in because I ordered the windshields from D&W, and they sent me these JURID wipers because they didn't have ATE in stock. Now I'm thinking about throwing away the still-very-good toppings – damn it!

Sure, here's the translation:

'Addendum:'
I scraped away the grooves again yesterday and noticed that the discs have already worn down significantly, while the pads are still almost at their 'new' thickness.

Hi,
Since I have my TÜV (German technical inspection) coming up this month, here's a question for the experts.
The groove on the ATE Powerdisc also serves as a wear indicator. After 90,000 kilometers, the groove is still visible but not particularly deep, so it will likely disappear completely in the near future. I can't visually assess the depth because it's dirty and covered with debris. The ventilation slots on the ventilated disc (on the inner side) are heavily corroded, and small pieces have broken off in some areas (on the inner side). The braking surface is essentially clean, but the inner and outer radii are slightly discolored, and the inner surface is less even. The braking performance is very good, and the pads show minimal wear (the outer, visible parts).
How does the TÜV (German technical inspection agency) handle the situation when the groove is still visible, meaning the wear limit has not yet been reached?
I am unable to translate "haithamina" because it does not appear to be a word or phrase in the German language. It may be a misspelling, a proper noun, or a term from a specialized field. If you can provide more context or clarify the intended meaning, I would be happy to assist you with the translation.

Based on my observations, measurements are not taken regularly, or only when there are specific reasons to do so, such as unusually high readings. There is little to argue against a positive assessment, provided that the visual appearance is satisfactory and the measured values meet the requirements.

Hi,
In the ATE Powerdisc, the groove also serves as a wear indicator. After 90,000 kilometers, the groove is still visible, but not particularly deep, which means it will likely disappear completely in the not-too-distant future. I can't visually assess the depth because it's covered in dirt and debris.

The groove is simply an additional, 'unofficial' wear indicator. The 'official' wear is measured by the minimum thickness, which is indicated on each brake disc. Whether you can still read them after years is another question...

The ventilation slots of the ventilated window (inside) are heavily corroded, and in some areas (inside), small pieces have chipped off.

This is only a concern if so many layers of leaf rust have gradually flaked off that the substance has been significantly reduced, thereby compromising its stability. This kind of thing happens very rarely.

The TÜV guidelines state that rust on friction surfaces should only be considered a defect in the following cases:

More than 20% of the width of the friction surface is unusable due to corrosion and is unlikely to regain functionality even after several forceful braking events.

3. The minimum thickness of the brake discs is being exceeded in certain areas. B. in rust craters or grooves.

2. The braking force values obtained on the brake testing equipment are insufficient or uneven.

Hello!

The choice of brake discs should also depend on their intended use. Unfortunately, I've learned that specialized brake discs only make sense if you drive your car almost every day. I often don't use my car at all during the week. Over time, a fine layer of rust forms on the brake discs, which then clogs the grooves or holes in the discs. This rust buildup eventually causes the disc to develop grooves itself, effectively eliminating the rust.

I've really experimented with a lot of different brake pads and invested quite a bit, but in the end, I ended up with standard, brand-name parts. Ideally, use ATE brake systems with ATE brake pads, and that's a good solution.

Regards,

Peter.

Ditto. For typical needs, it's the best and ultimately the most cost-effective solution.
Everything else is just individual.
