! WARNING !
At their most worn point brake pad
linings should not be thinner than
1mm, otherwise can lead to braking
failure.
! WARNING !
If brake pads are replaced too late
so that the lining is partly or entirely
worn, steel components of brake
pad will rub against brake disc,
thereby reducing braking effect and
destroying brake disc.
Replacing front brake pads
Remove calliper assembly away front
fork, unscrewing screws (1). Press the
brake calliper away from brake disc to
put the brake piston in its basic
position. Remove clips and the brake
pads from the calliper.
Clean the brake calliper and calliper
support with compressed air. Check the
sleeves of the guide bolts for damage
and grease guide bolts if necessary.
Mount both brake pads and then insert
the clips the right way, to allow brake
pads to jump off or lose, in order to
avoid accidents.
Tight the pegs over the clips at the front
calliper (if exist in the model).
Press brake lever several times until
brake gets tough and certify that front
wheel spins freely.
! WARNING !
Keep brake discs free from oil and
fatty materials; otherwise braking
effect will be strongly reduced.
Having performed any work on the
braking system, one must always
actuate hand brake lever or foot
brake pedal, to ensure that brake
pads will fit against brake disc and
pressure is established.
Changing the basic position of the
brake pedal
Free play can be changed by turning
piston (1).
Measured on the outside, the foot brake
pedal must have 3 to 5 mm of free play,
before the piston rod can move the
piston in the rear brake cylinder.
Checking rear brake fluid level
The reservoir for the rear disc brake is
integrated in brake pump, placed in the
right side of the engine, near exhaust
pipe.
