BRAKES 5C-25
Filling Master Cylinder Reservoir
CAUTION:
Use only specified brake fluid. Do not use any fluid which
contains a petroleum base. Do not use a container which
has been used for petroleum based fluids or a containe
r
which is wet with water. Petroleum based fluid will cause
swelling and distortion of rubber parts in the hydraulic
brake system. Water mixed with brake fluid lowers the
fluid boiling point. Keep all fluid containers capped to
prevent contamination.
Always fill the master cylinder reservoir when the engine
is cold.
Never allow the brake fluid to come in contact with the
painted surfaces.
The master cylinder reservoir must be kept properly filled
to ensure adequate reserve and to prevent air and
moisture from entering the hydraulic system. However,
because of expansion due to heat absorbed from the
brakes and the engine, the reservoir must not be
overfilled. Thoroughly clean reservoir cap before removal
to avoid getting dirt into reservoir. Add fluid as required to
bring level to the “MAX” mark on the reservoir tank. Use
“DOT 3” Hydraulic Brake Fluid.

Leakage of Brake Fluid
W ith engine idling, set shift lever in the neutral position and
continue to depress brake pedal at a constant pedal
application force.
Should the pedal stroke become deeper gradually, leakage
from the hydraulic pressure system is possible.
Make sure by visual check that there is no leak.




BLEEDING OF THE BRAKE HYDRAULIC
CIRCUIT
If air enters the bake lines, it will cause poor brake action.
Therefore, bleeding should be performed if the brakes have
been used with the level of brake fluid in the reservoi
r
excessively low or if brake pipes have been disconnected in
the course of brake servicing.
The bleeding operation calls for co-operative action of 2
persons.
• Set the parking brake firmly while bleeding.
• Perform bleeding operation with ENGINE RUNNING, to
prevent damage to push rod seal.
Make sure exhaust is suitably ventilated.
• Bleed the hydraulic system with the fluid reservoir filled to
the specified level.
• Bleed the system starting with the rear wheel cylinde
r
farthest from the master cylinder.

5. Vacuum Hose
The check valve (2) is built-in to the vacuum hose.
W hen installing the vacuum hose make sure that the arrow on
the hose is facing the engine (1).
Note:
• Do not apply oil to the vacuum hose.
• Installation direction is very important. The booster will not
operate if the vacuum hose is installed in the wrong
direction.
