Make sure that there is a certain
clearance between the brake ad-
juster and the point of contact,
to prevent the brake from remaining op-
erated and the consequent untimely
wear of the braking elements.
Clearance between brake adjuster and
point of contact: 0.5 ÷ 1 mm.
N Lock the pump control rod by means of
the lock nut (3).
Check the braking efficiency.
If necessary, contact an aprilia
Official Dealer.
After the adjustment, make sure that the
wheel rotates freely with released
brake.

means of the adjuster (6):
N Loosen the nut (7) (by screwing it).

stroke at the end of the clutch lever is
