The brake fluid must be renewed every year.
The reason for this is that the brake fluid absorbs moisture
through the vent hole in the reservoir. This moisture grad-
ually reduces the boiling point of the brake fluid from
240° C to 160 ÷ 180° C.
If this precaution is not taken, heavy use of the brake can
lead to steam formation and failure of the brake system.
Warning: Never allow brake fluid to contact the car's
paintwork. The brake fluid will damage the paintwork im-
mediately.
Connect the bleed device to the brake system reservoir.

Remove front wheel (36 10 300).
Push bleed hose with collection vessel on to bleed screw.
Open bleed screw.
When no further air bubbles emerge, close the bleed
scew.
Warning: On the 4-piston fixed calliper front brake all
3 bleed screws A, B and C must be bled, or else air bubbles
may be trapped in the brake caliper.
Note: Always bleed lower piston B before lower piston C.
