CHECKING THE BRAKE PAD WEAR
Carefully read page 33 (BRAKE FLUID -
recommendations), page 34 (DISC
BRAKES) and page 57
(MAINTENANCE).
NOTE The following information refer to
a single braking system, but are valid for
both.
Check the brake pad wear after the first
1000 km (625 mi) and successively every
2000 km (1250 mi) and before every trip.
The wear of the disc brake pads depends
on the use, on the kind of ride and on the
road.
WARNING
Check the wear of the brake pads,
especially before every trip.
To carry out a rapid checking of the
wear of the pads, proceed as follows:
u Position the vehicle on the stand, see
page 55 (POSITIONING THE VEHICLE
ON THE STAND).
u Carry out a visual check between the
disc and the pads, proceeding:
– from below, on the front part, for the front
brake calliper (1);
– from above, on the rear part, for the rear
brake callipers (2).
CAUTION
The excessive wear of the friction
material would cause the contact of the
pad metal support with the disc, with
consequent metallic noise and
production of sparks from the calliper;
braking efficiency, safety and
soundness of the disc would thus be
negatively affected.
If the thickness of the friction material
[even of one front (3) or rear pad (4) only]
has reduced to about 1.5 mm (or even if
only one of the wear indicators is not
visible any longer):
– for the front brake calliper have both
front brake calliper pads changed.
– for the rear brake calliper, have both
pads of the calliper changed.
WARNING
Have the pads changed by an aprilia
Authorised Dealer.
