	Risk of death caused by vehicle slipping or toppling off of the lifting platform.	Align vehicle between vehicle lift columns and position the four support plates at the vehicle lift support points specified by the vehicle manufacturer.	AS00.00-Z-0010-01A
	Notes on handling, transport and storage of composite brake disks	Model 190, 205, 213, 217, 222, 238, 253, 257, 290	AH42.10-P-9406-12LF
	Notes on handling, transport and storage of ceramic brake disks	Model 190, 197, 205, 212, 213, 217, 218, 222, 231, 253, 290 with code B07 (AMG - ceramic brake system)	AH42.10-P-9406-13A
	Check
1.1	Assess steel brake disks (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 disks on the rear axle For steel brake disks (1) with bores, assess crack length (x) including bore diameter. 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 disks (1). After obtaining special order. If soiling (e.g. oil, grease) is present, ↓ clean steel brake disks (1), and replace if necessary. After obtaining special order.
1.2	Assess ceramic brake disks (2) for damage and soiling (e.g. oil, grease). Notes on evaluating brake disks	Model 190, 197, 205, 212, 213, 217, 218, 222, 231, 253, 290 with code B07 (AMG - ceramic brake system) If the ceramic brake disks (2) are damaged or soiled, ↓ replace ceramic brake disks (2). After obtaining special order.	AH42.10-P-9406-07RQ
		If, in exceptional cases, assessment of the ceramic brake disks (2) is not possible by means of a visual check, ↓ check ceramic brake disks (2) for condition. After obtaining special order.	AP42.10-P-4246U
2.1	Assess steel brake disks (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 disks on the rear axle Steel brake disks (1) with wear bores.
	Notes on evaluating brake disks with and without wear holes		AH42.10-P-9406-14A
		If outer wear bore (11), center wear bore (12) and the inner wear bore (13) are visible, ↓ the steel brake disks (1) are OK; new brake pads can still be installed on the disks. If the inner wear bore (13) is visible, ↓ the steel brake disks (1) are OK, the current brake pads can still be used, do not install any more new brake pads onto the steel brake disks (1). If none of the three wear bores are visible, ↓ replace steel brake disks (1). After obtaining special order. If, in exceptional cases, assessment of the steel brake disks (1) is not possible by means of a visual check, ↓ check steel brake disks (1) for condition.

2.2	Assess steel brake disks (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 disks on the rear axle Steel brake disks (1) without wear bores.
