2.12.2. CHANGING THE BRAKE FLUID
Carefully read 1.2.1. and 1.3.1.
• Brake fluid must be changed every year.
NOTE These operations apply to both front and rear brakes.
WARNING
When using the fluid, take care not to spill it
on the plastic and painted parts, since it
damages them.
• Remove the rubber cap.
• Insert one end of a transparent plastic tubing inside the
caliper bleed valve (1-2) and the other end in a
container for collection.
• Loosen the bleed valve (1-2) of about one turn.
NOTE While carrying out this operation, check that some
fluid is always present inside the tank. If this is not the case,
once the operation is over, the air must be bled out,
2.12.5.
• Check that the fluid is flowing on the tank and, before
emptying, tighten the bleed valve (1-2).
• Top up, see
2.12.1 and 2.12.4.
• Loosen again the bleed valve (1-2) by about half of a
turn.
• Check that the fluid comes out of the plastic tubing
and, as soon as the fluid colour changes (from a darker
to a lighter colour) tighten the bleed valve (1-2) and
remove the tubing.
• Refit the rubber cap.
• Top up fluid inside tank, see 2.12.1 and
2.12.4.
