APRILIA RS 50 - 1999 Manual page 72

Carefully read p. 37 (BRAKES), p. 38
(DISC BRAKES) and p. 55 (MAINTE-
NANCE).
The following information refers to a
single braking system, but is valid for
both.
Check the brake pad wear after the first
300 mi (500 km) and then every 2,500 mi
(4,000 km).
The amount of wear that the brake pads
experience depends on how the motorcy-
cle is used, how aggressively it is driven,
and the condition of the roads upon which
it is operated. Wear will be faster than
normal when the motorcycle is driven ag-
gressively, or on dusty or wet roads.

PADS
Position the motorcycle on the stand.
Perform a visual check of the friction ma-
terial thickness. Use a flash light. See
the arrows (1) and (2) above.
If the friction material on one pad of a pair,
front (3) or rear (4), is worn to 0.06 in (1.5
mm) or less, replace both pads.
 
WARNING
Excessive wear of the friction material
would cause the contact of the pad met-
al support with the disc, with conse-
quent metallic noise and production of
sparks from the caliper; braking effi-
ciency and safety will be seriously com-
promised. This could lead to a crash,
with subsequent serious i njury or
death.
 
WARNING
Have the pads changed by your Local
Delear.
