Checking the front brake pads (LC4 Enduro)

The brake pads can be inspected from below. The linings must be at least
1 mm (0.04 in) thick.
AT THEIR MOST WORN POINT BRAKE PAD LININGS SHOULD NOT BE THINNER
THAN 1 MM, OTHERWISE THEY COULD LEAD TO BRAKE FAILURE. FOR YOUR OWN
SAFETY DON'T PUT OFF HAVING YOUR BRAKE PADS CHANGED.
IF THE BRAKE PADS ARE REPLACED TOO LATE SO THAT THE LINING IS PARTLY
OR ENTIRELY WORN AWAY, THE STEEL COMPONENTS OF THE BRAKE PAD WILL
RUB AGAINST THE BRAKE DISC, IMPAIRING THE BRAKING EFFECT AND DESTROY-
ING THE BRAKE DISC.

Checking the front brake pads (LC4 Supermoto)

The brake pads can be inspected from behind. Always inspect the brake pad
linings before taking off on your motorcycle. They should not be thinner than
1 mm (0.04 in) which is the case when the notch [A] is no longer discernable.
AT THEIR MOST WORN POINT BRAKE PAD LININGS SHOULD NOT BE THINNER
THAN 1 MM, OTHERWISE THEY COULD LEAD TO BRAKE FAILURE. FOR YOUR OWN
SAFETY DON'T PUT OFF HAVING YOUR BRAKE PADS CHANGED.
IF THE BRAKE PADS ARE REPLACED TOO LATE SO THAT THE LINING IS PARTLY
OR ENTIRELY WORN AWAY, THE STEEL COMPONENTS OF THE BRAKE PAD WILL
RUB AGAINST THE BRAKE DISC, SIGNIFICANTLY IMPARING THE BRAKING EFFECT
AND DESTROYING THE BRAKE DISC.

Changing the basic position of the foot brake pedal *

The basic position of the foot brake pedal can be altered by turning the stop
B
roller [1]. The free play at the foot brake pedal must then be adjusted by means
of the piston rod [2].
Measured on the outside, the foot brake pedal must have 3-5 mm (0.12–0.20
in) of free play, before the piston rod can move the piston in the brake cylin-
der (to be recognised from the resistance on the foot brake pedal).
NOTE: To prevent the stop roller from turning when tightening, counteract by
inserting a hexagon socket wrench in hole [B] provided for this purpose.
3-5mm
IF THIS FREE PLAY IS NOT PRESENT, THEN PRESSURE CAN BUILD UP IN THE
BRAKE SYSTEM WHEN DRIVING, CAUSING CONSTANT FRICTION OF THE BRAKE
PADS.THE BRAKING SYSTEM OVERHEATS AND CAN FAIL COMPLETELY IN EXTREME
CASES.
