| 1 | Assess all brake disks (1) for score marks, cracks, corrosion and soiling (e.g. oil, grease). | If the crack length (x) is > 25 mm (0.98 Inch) or if it extends up to the inner or outer edge of the friction ring, if there are gaping cracks or score marks deeper than 0.5 mm (0.02 Inch), or where pitted corrosion is present, ↓ replace brake disks (1). If soiling (e.g. oil, grease) is present, ↓ clean brake disks (1), replace if necessary. |
|
| 2.1 | Assess all brake disks (1) for wear. | Brake disks (1) with wear bores. | |
| Notice | Notes on evaluating brake disks with and without wear holes | If outer wear bore (11), center wear bore (12) and the inner wear bore (13) are visible, ↓ Brake disks (1) are OK; new brake pads can be installed on the disks. If the inner wear bore (13) is visible, ↓ Brake disks (1) are OK: the current brake pads can still be used, do not install any new brake pads on the brake disks (1). If none of the three wear bores are visible, ↓ replace brake disks (1). In exceptional cases, if an assessment of the brake disks (1) by visual check is not possible, ↓ check condition of brake disks (1). |

| 2.2 | Assess brake disks (1) for wear. | Brake disks (1) without wear bores. | |
| Notice | Notes on evaluating brake disks with and without wear holes | If deeply contoured ridging is present at the outer edge, ↓ replace brake disks (1). In exceptional cases, if an assessment of the brake disks (1) by visual check is not possible, ↓ check condition of brake disks (1). |
