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.
