Restoring The Brake Fluid Level; Checking Brake Pad Wear - APRILIA Atlantic 500 Workshop Manual

Periodic Maintenance Operations

RESTORING THE BRAKE FLUID LEVEL

Read through the paragraph DISC BRAKES.
Remove the four screws (2) from brake fluid reservoir
(3).
Remove cover (4).
NOTE
To avoid spilling the brake fluid when topping
up, ensure that the fluid in the reservoir is parallel with
the reservoir rim (in a horizontal position).
Remove the gasket under the cover.
NOTE
To fill the reservoir to the MAX level, ensure
that the rim of the brake fluid reservoir is parallel with
the ground and add fluid until sight (5) is completely
covered.
CAUTION
Top up to the MAX level only if the brake pads are
new.
The level of the fluid gradually decreases with pad
wear.
Topping up to the MAX level when the pads are
worn will cause the brake fluid to overflow when
the pads are replaced.
Fill reservoir (3) with brake fluid (see LUBRICANT
CHART) until sight (1) is completely covered.
To refit the components, follow the reverse procedure
to the removal.

CHECKING BRAKE PAD WEAR

Read through the paragraph DISC BRAKES.
The following information are referred to one
braking system only, but are valid for both.
Check the brake pad wear after the first 1,000 km (625
mi) and successively every 2,000 km (1,250 mi).
The wear of the brake pads depends on the use, on
the kind of drive and on the road.
The wear is heavier when driving on dirty or wet
roads.
FRONT BRAKE CALIPER
– Front side from the bottom for both calipers.
REAR BRAKE CALIPER
– Rear side from the bottom for both pads (C).
WARNING
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 caliper; braking
efficiency, safety and soundness of the disc would
thus be negatively affected.
• If the thickness of the frictional material (also of
one pad only) becomes 1.5 mm (0.059 in), replace
both pads (both front and rear pad).
