Inspecting The Brake Liquid; Bleeding The Air - Yamaha TZR50 '03 Service Manual

INSPECTING THE BRAKE LIQUID /

BLEEDING THE AIR

3-22
NOTE:
• Place the motorcycle vertically to check the
level of the brake liquid
• When checking the front brake liquid level,
make sure that the top side of the master
cylinder is horizontal, moving the handlebar
if necessary
CAUTION
The brake liquid can erode the painted sur-
faces and the plastic parts: always imme-
diately clean any liquid spilt.
s WARNING
s
• Use only brake liquid of the specified qua-
lity; otherwise the rubber seals might dete-
riorate, which would give rise to leakages
and a reduction in the effectiveness of the
brakes
• Fill up again with liquid of the same type;
the mixture of different liquids might give
rise to detrimental chemical reactions and a
consequent drop in efficiency. Take care
that water does not get into the master
cylinder when filling up.
• Water makes the boiling point of the liquid
drop considerably and may give rise to an
obstruction through vapour.
BLEEDING THE AIR
s WARNING
s
The brake system must be bled in the follo-
wing cases:
• When the system has been dismantled
• When a brake sleeve has been loosened
or dismantled
• When the brake liquid level is too low
• When the brake operation is faulty
• There may be a dangerous drop in braking
capacity if the system has not been pro-
perly bled.
1. Bleed:
• The brake liquid
