1. Inspect:
•Caliper piston (1)
Scratches/wear/rust ➔Replace caliper
assembly.
•Caliper cylinder (2)
Scratches/wear ➔Replace caliper assem-
bly.
•Caliper (3)
Cracks/damaged ➔Replace the brake
caliper assembly..
Recommended programme for the replace-
ment of brake system components:
Brake pads When necessary
Brake hoses Every four years
Replace every
24,000 km or 24
Brake fluid months and when-
ever the brake is
disassembled.
WARNING
All internal brake components should be
cleaned and lubricated with new brake fluid
only before installation. Do not use solvents to
prevent sealing elements from becoming mis-
shapen or swollen.
WARNING
•Never try to pry out the caliper piston.
•Cover the caliper piston with a rag. Be
careful not to get injured when the piston
is expelled from the master cylinder.

Brake fluid may deteriorate painted surfaces
or plastic parts. Always clean up spilled fluid
immediately.
CAUTION:
WARNING
•Use only designated quality brake fluid.
Otherwise, the rubber seals may deterio-
rate, causing leakage and poor brake per-
formance.
•Refill with the same type of brake fluid:
mixing fluids may result in a harmful chem-
ical reaction and lead to poor perform-
ance.
•Be careful that water does not enter the
significantly lower the boiling point of the
fluid may result in vapor lock.
4. Inspect:
•Brake fluid level
Lower than “MIN” mark ➔Fill.

DO NOT:
•Remove brake components from the
motorcycle unless is absolutely necessary.
•Use solvents on internal brake components.
•Use brake fluid already used for bleeding.
•Allow brake fluid to come into contact with
the eyes as it may cause injury.
•Allow brake fluid to come into contact with
painted or plastic parts as it may damage
them.
•Disconnect any hydraulic connection, other-
wise the whole system must be disassem-
bled, drained, cleaned, then properly filled
and bled after reassembly.
CAUTION:
NOTE:
It is unnecessary to disassemble the brake hose
to replace the pads.
NOTE:
•If you replace the pads, also replace the pad
support.
•If one of the two pads has to be replaced
because it is worn, replace both.
