Extensive quality management and continuous process development ensure high levels of quality with every Bosch brake disc.

Their homogeneous casting structure as well as their compliance with particularly low tolerances concerning lateral runout and differences in thickness, exceed the ECE-R90 specifications. Bosch brake discs deliver increased driving comfort and reliably provide additional safety, even in case of extreme situations.


The worldwide Bosch range of brakes consists of more than 40 000 products. The extensive product range includes wearing parts, hydraulic products and components, workshops therefore find matching brake components for almost any vehicle. Bosch discs cover more than 95 % of the European market.
