UNIT REPAIR
MASTER CYLINDER
• The master cylinder is not repairable and must
be replaced as complete assembly if found
defective.
INSPECTION
Excessive brake pedal travel, malfunction or dragging
brake suggests
that the master cylinder is defective. In
such cases perform the following visual check.
IL•I Visual check
Make parts replacement as required if wear, distortion,
nicks, cuts, corrosion,
or other abnormal conditions
are
found through the following parts inspection;
• Master cylinder body
• Fluid reservoir
• 0-ring
rfil FUNCTIONAL INSPECTION OF MASTER
l..!aJ CYLINDER PISTON (Fig. SA-20)
Push the primary piston with your fingers to check that
it travels smoothly. If the motion is questionable,
replace
the master cylinder as a complete assembly.
