	Check
1	Assess brakepad thickness (1) of brakepads on front axle.	If the wear limit of the brakepads has been reached, replace the brakepads subject to a separate repair order. Otherwise the braking effect may be impaired and people, property and environmental damage may result.
		If necessary, use flashlight (2) or mirror (3). To assess the brakepad thickness (1), take the thickness of the backing plate as a reference point and identify the brakepad with the smallest brakepad thickness (1) on each axle.
		For racetrack operations, the customer should be advised to change the brakepads prematurely at 9 mm (steel) or at 7 mm (ceramic) brakepad thickness (1).
