Stop in time, every time. While braking, most pressure is applied on the brake disc. Made from high-quality cast steel, Bosch Brake Discs are resistant to corrosion and wear, providing assured stopping power over a long operating life. Designed for high performance in the most extreme conditions, Bosch Brake Discs are featured as original equipment by leading auto-makers in their vehicles.
Cast in Steel - Improved engine performance and higher vehicle weights are increasing the quality requirement for braking systems. Only brake discs made from high-grade materials and homogenous casting structures without trapped air and friction will meet the specifications of the car manufacturers.
Minimal Tolerances for Disc Thickness Variation (DTV) and Run-out: These characteristics are essential for best braking comfort. Considerable variation of the friction ring’s thickness generates immediate vibrations (oscillating brake torque) which cause brake judder and noise.
Always Replace in Pairs: Brake discs are subject to wear and should always be replaced as two per axle as soon as one of them drops below the recommended minimum thickness.
Say Goodbye to Braking TroubleBrake vibrations and squealing are usually caused by irregularities on the brake disc surface or by a side run-out of the disc.
However, excessive slackness of the wheel bearings, the wheel suspension and even the steering conduction components can be a factor too. Professional repairs and the use of high-quality spares help eliminate these problems.
