While deriveting, ensure that the holes in the
shoe rim are not enlarged.
Clean the shoe rim to ensure a smooth even surface
for the lining.
Always use genuine linings during relining,
including the rivets supplied along with the
relining kit.
Clamp the lining evenly to the shoe rim, and start
riveting at the centre and progress outwards to the
end of the shoe. A flat ended anvil of the correct
diameter should be used against the rivet head and
the tubular shank of the rivet should be properly
clinched.
Care should be taken, since over riveting may crack
the lining. Ensure that no clearance exists between
the lining and the shoe rim.
Fit the hand brake operating lever to the trailing shoe
in the reverse order of removal.
Ensure that the spring plate convex side is towards
the retaining plate.
Make sure the lever is free to operate.
Do not contaminate the lining surface with oil or
grease.
Refit the shoes in accordance with the following
instructions :

1) Tips of new shoes - Graphite grease
2) Hand brake strut slots - Graphite grease.
3) Adjuster Pushrod Threads - Mineral oil base
grease.
Note :

and the shoes in the abutment groove. Hook the
shoe return spring (7) (short length coil) to the
leading shoe, with the adjuster assembly in its
minimum length condition, assemble the adjuster
assembly between the shoe webs. Attach the other
end of the shoe return spring (7) to the opposite end
of theTrailing shoe (3).Adjust the length of the adjuster
until the shoes will clear the wheel cylinder pistons.
