T42.10-0045-01

Thickness of the brake pad

2 Brake lining

3 Pad's plate

d Thickness of the new brake lining

E Thickness of the brake lining at minimum measurement

	Check:
1	Remove the wheels.
	Remove the front and the rear wheels		AR40.10-B-1100E
2	Check the brake pads for thickness	On vehicles fitted with electric indicator, check brake pad wear through the instrument cluster.
		If the minimum brake pad measurement (E) is reached, the same has to be replaced: 
		Remove and install the brake pads	AR42.10-B-0170B
		Minimum brake pad lining thickness	*BE42.10-B-1001-11A
		Thickness of new brake pad lining	*BE42.10-B-1004-11A
3	Clean the brake discs (1) before checking
4	Measure the thickness of the brake discs (1)	Front axle	*BE42.10-B-1001-08A
		Rear axle	*BE42.10-B-1001-09A
		If the permissible wear measurement (B) is exceeded, replace the brake discs (1), otherwise the safety in traffic will be compromised. 
		Removing and installing the front axle brake disc	AR42.10-B-0230B
		Removing and installing the rear axle brake disc	AR42.10-B-0240A
5	Install the wheels
	Install the front and the rear wheels		AR40.10-B-1100E
