Scrap treatment；(9.4.4), the certified products to the detection more than carry out surfacecti proteon treatment and mark；
(9.5), brake each several part is detected, specially：(9.5.1), range estimation, will have a bottom deformation and can not repair
Brake directly scraps treatment；(9.5.2), each installation position of measurement brake, do not reach dimension precision requirement scraps treatment；
(9.5.3), the wear intensity to brake accessory are measured, and do not reach requirement scraps treatment；(9.5.4), to passing through more than
The certified products of detection carry out surfacecti proteon treatment and mark；
(9.6), brake drum is detected, specially：(9.6.1), range estimation, outer surface is had to collide with and is scrapped with the direct of defect
Treatment；(9.6.2), magnaflux and ultrasonic examination machine testing are carried out to brake drum, it is defective to scrap treatment；
The wear intensity of (9.6.3), measurement brake drum, do not reach dimension precision requirement scraps treatment；(9.6.4), to being examined more than
The certified products of survey carry out surfacecti proteon treatment and mark；
(9.7), other parts are detected, specially：(9.7.1), range estimation, by direct report that is defective and can not repairing
Useless treatment；(9.7.2), each position installation dimension of other parts is measured, do not reach dimension precision requirement scraps treatment；
(9.7.3), the certified products to the detection more than carry out surfacecti proteon treatment and mark.
