INSPECTION
Observe for wheel cylinder leak by lifting the
rubber dust covers (2.1) on the cylinder. If leak is
observed replacement of kit is recommended. If
no leak is observed, check the pistons (2.2) for
freedom of movement and temporarily fit an
elastic band around the cylinder to retain the
pistons in the bore.
CLEANING
Clean the back plate thoroughly. Use a wire brush
to remove any corrosion, but take care not to
damage the rubber dust covers on the wheel
cylinder.
Note: Never use petrol or kerosene, or paraffin
etc. for cleaning brake parts as they are
dangerous.
Ensure shoe-sliding platforms on the back plate
(1) are smooth and not corroded. If necessary,
clean the filings and apply a light smear of
Graphite grease (high melting point grease) to
each platform.
Examine the adjuster assembly to see it is in good
working order and ensure the adjuster nut is free
to run the full length of the thread. Care must be
taken to fit left and right hand thread nuts
properly.
