Check brake disc wear
WARNING
!
When checking the brake disc wear, apply the parking brake
and secure the front and rear frames with the safety bar.
!
Make sure that the brake oil temperature is less than 60°C
before checking the brake wear.
!
If the disc is near the wear limit, carry out inspection at
shorter intervals, regardless of the specified inspection inter-
val.
When checking the brake disc for wear, there are 4 places (front
axle and rear axle, left and right), so use the same procedure to
check all 4 places.
1. Remove cap nut (1).
2. Depress the brake pedal and push in rod (2) fully.
3. Amount of wear (A) is the amount that end face (C) of the
rod protrudes from end face (D) of the guide. Measure the
amount of protrusion.
Permitted wear limit (B) of the disc is the point where groove
(E) of the rod is in line with end face (D) of the guide.
When this point is reached, please ask your KOMATSU dis-
tributor to carry out inspection and replacement of parts.
