Check
- Check surface and thickness of brake discs.
Result
» Brake disc thickness has fallen below the minimum.
Scoring, heat cracks or thickness differences are present.
Measure
- Replace brake discs.
See: 34 11 220 removing and installing/replacing both FRONT BRAKE DISCS (16-inch brake)
Measure minimum brake disc thickness (front brake)
- Check minimum brake disc thickness:
Place the special tool 0 495 451 (34 1 280) at three measuring points in area (1) and measure.
Compare measurement result and lowest value with setpoint value.
New brake pads must only be installed if the brake disk thickness is greater than the minimum brake disc thickness.
