	Checking
	Risk of poisoning caused by swallowing brake fluid. Risk of injury caused by brake fluid coming into contact with skin and eyes.	Only pour brake fluid into suitable and appropriately marked containers. Wear protective clothing and eye protection when handling brake fluid.	AS42.50-Z-0001-01A
	Brake fluid notes		AH42.50-P-0001-01A
	Notes on repairs to brake system		AH42.00-P-0003-01A
1	Check fluid level in brake fluid reservoir (1), correct if necessary	The fluid level must be between the "MIN" and "MAX" marks embossed in the brake fluid reservoir (1). If the brake fluid level is too low, determine the cause and rectify: ↓
		Check brake pads for lining thickness and condition of brake discs. Wear at the brake linings reduces the fluid level in the brake fluid reservoir (1). In this case, do not top up the brake fluid but instead replace worn components.	AP42.10-P-4251G
	General brake fluid		BB00.40-P-0330-01A
	Brake fluids (DOT 4 plus)		BB00.40-P-0331-00A
2	Check leaktightness of brake system	If there is a loss of brake fluid, i.e. the fluid level is below "MIN", determine and rectify against a separate repair order:
	Test brake system with pressure tester for leaks	Model 460, 461, Model 463 except 463.270 /271 and except 463.236 /248 with code (979) Special protection version	AR42.10-P-0015GG
		Model 463.270 /271	AR42.10-P-0015GX
	Inspect braking system for proper operation and leaks	Model 463.236/ 248 with code (979) Special protection version	AR42.10-P-0014GS
