Disc brakes have to be reliable. And Bosch disc brakes are even more reliable than you might expect. Thanks to the use of high-quality materials they even cope with extreme strains. Just one example: On full braking, the braking power is several times higher than the engine power. Temperatures in excess of 750°c can then arise between the pad and the brake disc. Only absolute top quality is able to withstand such extreme thermal and mechanical stress over the course of time - in other words, Bosch quality.
