APRILIA RS 50 Workshop Manual page 53

Routine maintenance operations
WARNING
Do not go over the "MAX" level when topping up.
Fill to the "MAX" level only when new pads are
fitted.
The fluid level decreases gradually as the pads
wear down.
Do not fill to the "MAX" level with worn pads, as
the fluid will spill out when the brake pads are
replaced with new ones.
NOTE
The peep-hole (2) can be used as a reference
for filling to the "MAX" level: with the top edge of the
brake fluid reservoir parallel to the ground, fill until the
peep-hole (2) is completely covered by the fluid.
Fill the reservoir with brake fluid see (LUBRICANT
CHART) until the peep-hole is completely covered.
Replace the gasket (5) in its seating.
Replace the top (4).
Screw in and tighten up the two screws (3).
WARNING
Check the efficiency of the brakes.
If the brake lever has too much play or is too
loose, or if there are air bubbles in the circuit, then
the air may need to be bled out of the system.
