J Lay the shoes on a bench with the "toe" of one shoe
f adjacent to the "heel" of the other.

Fit the return springs (I and 2) to the underside of
the brake shoe flanges in the positions shown in
Fig. 4.
Offer up the shoes complete with springs to the
backplate and locate the toe of the leading (rear­
most) shoe In the slot in the wheel cylinder piston.
The handbrake lever should locate in the slot In the
flange of the leading shoe. Position the "heel" of
the leading shoe in the slot In the adjuster link.
Prise over the trailing shoe Into its relative position
as shown in Fig. 4.
Insert the hold-down pegs (12) through the holes
in the backplate and replace the leaf springs (11)
smeared with white brake grease.
Clean out the brake drum and refit, securing with
the countersunk screw.
Adjust the brake as previously described.
Immediately after fitting replacement shoes It is
advisable to slacken back the adjuster one further
click to allow for possible lining expansion, reverting
to normal adjustment afterwards.
Several hard applications of the brake pedal should
be made to ensure all the parts are working satis­
factorily and the shoes bedding to the drums. Refit
road wheel, lower the jack and test.
The above instructions hold true for both rear
brakes.
To reline
It Is strongly recommended that advantage be
taken of the Factory Reconditioned Service Unit
Scheme, whereby replacement brake shoe 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.
3. Grip the shoe
lightly
In a vice, In order not to
distort the shoe. Cut away the portion of each
rivet which protrudes through the underside
of the brake shoe platform with a sharp chisel.
Position the shoe In the vice so that It Is held
as near as possible to the rivet being removed.
Repeat for the other shoe.
-4. Thoroughly degrease the shoes.
5. Inspect each shoe carefully for damage and
cracks. Apply marking to the shoe platform and
roll It against a flat surface, noting any high
spots and removing them with a file.
6. Place the new lining on the shoe, lining the ends
up with the marks previously scribed, first
ensuring that there Is no foreign matter adhering
to Its underside.
7. Mount a rivet dolly In the vice. Flt the rivets In
pairs starting at the centre pair and working
outwards towards the ends. Each shoe will
require ten copper or brass rivets of the dimen­
sions shown In Fig. 6. When riveting, hold the
head firmly against the anvil and secure using
a suitable punch. Make sure that there is no
