Topical note Notes on handling, transport and storage of Model 190, 205, 213, 217, 222, 238, 253, 257 AH42.10-P LF composite brake disks Topical note Notes on handling, transport and storage of Model 190, 197, 205, 212, 213, 217, 218, 222, AH42.10-P A ceramic brake disks 231, 253 Check 1.1 Assess steel brake disks (1) for score marks, Model 117, 156, 164, 166, 169, 171, 172, 176, cracks, corrosion and soiling (e.g. oil, grease). 203, 204, 207, 209, 211, 219, 221, 230, 238, 242, 245, 246, 251, 253, 292, 453, , 231 and For perforated or counterbored steel brake disks (1) assess the crack length (x) including the bore diameter. Otherwise the assessment may be incorrect. If a crack length (x) is 25 mm (0.98 inches), split open cracks or score marks are deeper than 0.5 mm (0.02 inches), or severe corrosion is present. If soiling (e.g. oil, grease) is present. Clean steel brake disks (1), and replace if necessary. 1.2 Assess ceramic brake disks (2) for damage Model 190, 197, 205, 212, 213, 217, 218, 222, and soiling (e.g. oil, grease). 231, 253 Notes on evaluating brake disks AH42.10-P RQ If the ceramic brake disks (2) are damaged or soiled. Replace ceramic brake disks (2). Page 2 of 5

3 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.

Model 117, 156, 164, 166, 169, 171, 172, 176, 177, 203, 204, 207, 209, 211, 216, 219, 221, 230, 238, 242, 245, 246, 251, 257, 292, 453, , 231, 253 and Steel brake disks (1) with wear bores. Topical note Notes on evaluating brake disks with and AH42.10-P A without wear holes 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 brakepads can still be installed on the disks. If the inner wear bore (13) is visible. The steel brake disks (1) are OK. The current brakepads can continue to be used. New brakepads may no longer be installed on the steel brake disks (1). If none of the three wear bores are visible. 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.
