| 1.1 | Assess steel brake discs (1) for score marks, cracks, corrosion and soiling (e.g. oil, grease). | Model 117, 118, 156, 164, 166, 167, 169, 171, 172, 176, 177, 203, 204, 207, 209, 211, 216, 219, 221, 230, 238, 242, 245, 246, 247, 251, 257, 292, 293, 453, 461, 463 Model 190, 197, 205, 212, 213, 217, 218, 222, 231, 253, 290 except code B07 (AMG - ceramic brake system) Model 205 with code B07 (AMG - ceramic brake system) and steel brake discs on the rear axle 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 steel brake discs (1). If soiling (e.g. oil, grease) is present, ↓ clean steel brake discs (1), and replace if necessary. |

| 2.1 | Assess steel brake discs (1) for wear. | Model 117, 118, 156, 164, 166, 167, 169, 171, 172, 176, 177, 203, 204, 207, 209, 211, 216, 219, 221, 230, 238, 242, 245, 246, 247, 251, 257, 292, 293, 453, 461, 463 Model 190, 197, 205, 212, 213, 217, 218, 222, 231, 253, 290 except code B07 (AMG - ceramic brake system) Model 205 with code B07 (AMG - ceramic brake system) and steel brake discs on the rear axle Steel brake discs (1) with wear bores. |
|
| Notice | Notes on evaluating brake discs with and without wear holes | If outer wear bore (11), center wear bore (12) and the inner wear bore (13) are visible, ↓ the steel brake discs (1) are OK; new brake pads can still be installed on the discs. If the inner wear bore (13) is visible, ↓ the steel brake discs (1) are OK, the current brake pads can still be used, do not install any more new brake pads onto the steel brake discs (1). If none of the three wear bores are visible, ↓ replace steel brake discs (1). If, in exceptional cases, assessment of the steel brake discs (1) is not possible by means of a visual check, ↓ check steel brake discs (1) for condition. |
