CHECKING THE BRAKE PAD WEAR
Carefully read page 26 (BRAKE FLUID-
recommendations), page 26 (DISC
BRAKES) and page 43 (MAINTENAN-
CE).
The following information refer to a sin-
gle 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).
The wear of the brake pads depends on
the use, on the kind of drive and on the
road. The wear will be greater when the ve-
hicle is driven on dirty or wet roads.
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:
◆
Position the vehicle on the stand.
◆
Carry out a visual checking of the friction
material thickness by looking between
the brake caliper and the pads.
Proceed:
– from below, on the front part, for the
front brake caliper (1);
– from below, on the rear part, for the rear
brake caliper (2).
The excessive wear of the fric-
tion material would cause the
contact of the pad metal support
with the disc, with consequent metallic
noise and production of sparks from the
caliper; braking efficiency, safety and
soundness of the disc would thus be
negatively affected.
◆
If the thickness of the friction material
(even of one pad only) has reduced to
about 1 mm, replace both pads.
– Front pad (3).
– Rear pad (4).
Have the pads changed by your
Concessionario Ufficiale aprilia.
