3.6. Lubrication and Maintenance Operations
With brake shoe lining replaced the
brake eciency will lower and stopping
distance will get longer. Adapt driving
mode and braking mode to this case!
Check brake cylinder for any leakage of brake uid.•
When checking is completed reinstall the drums. Turn brake •
drum with its adjustment hole pointing downward towards
adjusting wheel. Rotate adjusting wheel (1) until brake clips
lean against brake drum (brake drum unable to rotate). Turn
a bit the adjusting screw backward by only such turn so the
brake clips get released (brake drum able to rotate freely).
Carry out brake clip adjustment during:
Insucient brake eciency (long step of
brake pedal)
Replacement of worn clips for new ones
Following the installation of new brake
drum or after brake drum’s inner diam-
eter is machined (refer to Workshop
Service Manual).
If, while checking, you nd lining thick-
ness is 4 mm (0,16”) or smaller, please
check lining after next 500 operating
hours.
Replace lining always when thickness
reaches min value of 2 mm (0,08”).
Replace all brake clips at one time to
maintain uniform braking!
Always replace adjusting mechanism de-
fected with new one.
When replacing, use original brake clips
only!
Before installing wheels onto the brake drums following the •
brake repair, please point the brake drum bolts against holes
in the wheels using an appropriate lever so to avoid damage
of bolt threads, reinstall wheels, tighten wheel nuts with 400
Nm (295 lb ft) torque.
