Precautions
lRecommended fluid is brake fluid ``DOT 3'' or ``DOT 4''.
Refer to MA section (``Fluids and Lubricants'', ``RECOM-
MENDED FLUIDS AND LUBRICANTS'').
lDo not reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas.
lWhen removing and installing clutch piping, use Tool.
lUse new brake fluid to clean or wash all parts of master
cylinder, operating cylinder and clutch damper.
lNever use mineral oils such as gasoline or kerosene. It
will ruin the rubber parts of the hydraulic system.

PRECAUTIONS AND PREPARATION
CL-1

Adjusting Clutch Pedal
1. Adjust pedal height with pedal stopper.
2. Adjust pedal free play with push rod.
Air Bleeding Procedure
Bleed air according to the following procedure.
Bleed the air from the master cylinder (RHD models only)
and then the operating cylinder.
1. Fill the master cylinder reservoir tank with new brake fluid.
2. Connect a transparent vinyl hose to the air bleeder.
