All brake discs from TRW have an ABE. The discs are low-wear and have up to 30% longer life compared to some comparable brake discs. The discs are made of extremely dimensionally stable and hardened steel. The precise surface grinding (thickness deviation of 2/100mm) avoids vibrations and improves the adjustment of the pads. An even temperature build-up and reduction enables a constant pressure point. A new special alloy prevents excessive corrosion. Laser technology enables a lightweight construction with fine contours.
