Material and Processing - Superior Quality Cast Steel

The production of brake discs requires in-depth know-how and extreme precision. Bosch selects cast- ing materials and alloying constituents based on long experience. Rigorous testing at Bosch testing facilities and independent institutes assures a consistently high quality standard - for safety, reliability and long life.

Low Tolerances

Bosch's experience in processing original equipment brake discs also guarantees minimum tolerances for run-out and disc thickness variation (DTV). Excessive run-out produces DTV, which in turn causes pedal vibrations, steering wheel or entire wheel pulsation, and brake noise.

Bosch recommends:

To maintain safety, follow this simple checklist:

1. Check the disc thickness: If it falls below the required minimum, replace the brake discs in pairs
2. Inspect the front axle and steering
3. Check the wheel bearing play
4. Clean the wheel hub (do not use paste lubricants)
5. Check the wheel hub for lateral run-out
6. Ensure the mobility of the brake caliper
7. Tighten the wheel bolts with a torque wrench
