turning the "mlcram" adjuster anti-clockwise to
the full extent using a screwdriver. (See Fig. 10).
Remove the brake drum and distanc� piece, when
fitted, from the axle flange by withdrawing a
countersunk screw. A light blow on the side of
the brake drum will loosen it and facilitate removal.
Release the damper spring assemblies (item 18, Fig.
16) by depressing the cups and turning the pegs
through ninety degrees. The pegs may be withdrawn
from the rear of the backplate.
Disengage the leading (rearmost) shoe from the
locating slots In the wheel cylinder piston and
abutment by pulling it against the tension of the
pull-off springs. The trailing shoe will then auto­
matically be released.
Remove the "micram" adjuster and mask from the
toe end of the leading shoe.
To refit (See Fig. 16)
Lay the shoes on a bench with the toe of the leading
shoe adjacent to the heel of the trailing shoe.
Connect the two-coiled pull-offspring (13), between
the toe of the leading shoe and the heel of the
trailing shoe, with the longer coil nearest the leading
shoe. Use the outer of the two holes when hooking
It to the heel end of the trailing shoe.
Similarly connect the single-coll pull-offspring (15),
between the heel of the leading shoe and the toe of
the trailing shoe, with the coiled portion facing
inwards. Use the Inner of the two holes when
hooking It to the heel end of the leading shoe. Both
springs should be fitted to the
underside
of the
brake shoe flanges.
Fit the "mlcram" adjuster (1) and mask (2) into the
slot at the toe of the leading shoe.
Offer up the shoes complete with pull-off springs to
the backplate and locate the leading shoe In the slots
in the wheel cylinder piston (3) and abutment (16).
Prise the trailing shoe into position with its ends
ocating in the wheel cylinder body (11) and
abutment. Refit the damper spring assemblies (18),
(reversal of the removal procedure).
Refit the brake drum and distance piece, when
fitted; secure with the countersunk screw and
adjust the brakes as described under"Maintenance".
Lower the jack and remove the chocks.
To reline
It Is strongly recommended that advantage be taken
of the Factory Reconditioned Service Unit Scheme
whereby replacement brake shoe and lining assem­
blies can be obtained In exchange for the old ones.
In territories where these facilities are not available
relining may be carried out as follows:-
1. Remove the brake shoes as previously described.
2. Mark the position of the lining across each end
of one of the brake shoes with a scriber. This
will ensure that the new lining will be fitted In
the correct position.
