	Check
	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
	Risk of injury . Skin or eye injuries may result when handling hot or glowing objects.	Wear protective gloves, protective clothing and safety glasses, if necessary.	AS00.00-Z-0002-01A
	Notes on repairs to brake system		AH42.00-P-0003-01A
1	Assess lining thickness (1) of brake pads on front axle	If necessary, use lamp (2) or mirror (3). The thickness of the pad backing plate can be used as a guide when assessing brake lining thickness.
1	Assess lining thickness (1) of brake pads on front axle	Brake shoe If, in exceptional cases, assessment by means of visual inspection is not possible, ↓ remove wheels to conduct assessment, subject to separate repair order.	*BE42.10-P-1001-05H
2	Assess lining thickness (1) of brake pads on rear axle	If necessary, use lamp (2) or mirror (3). The thickness of the pad backing plate can be used as a guide when assessing brake lining thickness.
2	Assess lining thickness (1) of brake pads on rear axle	Brake shoe If, in exceptional cases, assessment by means of visual inspection is not possible, ↓ remove wheels to conduct assessment, subject to separate repair order.	*BE42.10-P-1001-15G
3	Determine remaining distance of brake pads		AP42.10-P-4253-03EW
3	Determine remaining distance of brake pads	If the wear limit for the brake linings is reached, the brake pads must be replaced subject to separate repair order. Otherwise the braking effect may be impaired and people, property and environmental damage may result! Per axle, the brake pad with the least lining thickness is to be used for determining likely remaining distance. In order to avoid an unscheduled workshop visit between services, it is necessary to determine the remaining distance of the present brake linings. If the remaining distance determined is smaller than the next service interval, premature brake pad replacement should be recommended to the customer.	AP42.10-P-4253-03EW
