Buderus Guss iDisc brake discs – Future of brake discs

The revolutionary product for brake discs


The braking pads from Bosch named iDisc is a production product from their ”related” branch company Buderus Guss (Germany), that produce up to 90 percent less dust during braking, thickness of a thumb this new invention is a revolution product in the future production for manufacturing braking discs.

Long before ABS ( anti-lock braking system), ESP (electronic stability program), airbags and other security systems, the disc brakes make the drive safer and the stopping distance is significantly shorter, thus contributing to the prevention of numerous traffic accidents.

The highest amount of polluted environment is not caused only by fuels such as diesel or petrol but the friction of the tires and the brakes as well. According to the Environmental Protection Agency of Baden-Württemberg (Germany), brakes and tires are responsible for 32 percent of particulate emissions causing pollution to the environment while driving about the half of the percentage which produces dust from the braking systems it self (brake pads and disc’s). 


That’s why the company Bosch Buderus Guss has developed the iDisc. Compared to conventional disc brakes, this iDisc produces up to 90 percent less dust or less particulate emissions during braking.

The unique iDisc feature (“I” means innovation) is a tungsten carbide coating currently available only in Buderus Guss (Germany). The technology is based on conventional iron plated discs, and each year the subsidiary company of Bosch produces up to 20 million of these disks in their plants in Germany in Bridenbach and Ludwigshut.

In order for the conventional disc to become iDisc, the friction surfaces are machined mechanically and thermally coated precise for the application of the final layer, but as far as the price is concerned.

The iDisc is about three times more expensive than a conventional iron disk, and three times cheaper than a ceramic brake disc so it actually it make’s more like a middle price brakes with great performance.

But the price will be come to its everyday standards because, as the volume for the production vehicle has increased, the car manufacturer company demand the braking disk’s on their future production cars, so over the past year 330 million units are made.


No rust at all – iDisc

In addition to drastically reducing the amount of dust due to braking, the iDisc carbide coating provides greater safety during use, the test result shown that the braking performance is similar to the ones with ceramic material, especially when it comes to hot friction they wouldn’t worn so fast like the standard cheapest one at the auto store.

Corrosion was a common problem for the standard steel brakes, well you wont see that on the iDisc which is a big advantage, especially for electric vehicles, EV’s on the other hand perform less pressure on the brakes and it often happens that rust is shown on the frictional surfaces which occurs in a short period of time, especially in a wet or rainy environment.
