Brake Shoe Removal and Replacement
After the brake plate has been removed from the wheel, the brake cam lever should
be detached and the cam spindle pushed in slightly to allow the shoes to clear the
brake plate. Insert a screwdriver between the brake shoes at the fulcrum pin and twist
the screwdriver.
Place a small lever between one of the shoes and the cover plate and lever the
shoe away from the plate until the spring pressure is released. Both shoes can then be
lifted away from the cover plate.
The shoes can then be replaced by the reverse procedure. Hook the springs on
to the shoes and place the ends of the shoes in position on the fulcrum pin and cam
lever. Then push the shoes outwards until the springs pull them into their correct
position.

OTE
:—The brake shoe springs are quite strong and care should be taken that
the fingers are not trapped by the brake shoes during these operations.
Brake Shoe Relining
With the shoes removed the linings can best be removed by drilling away the heads
of the rivets and punching the shanks out to the inside of the shoes with a suitable
drift.
New linings are die pressed to suit the curvature of the shoes, but will require
drilling and counter-boring for the rivets. Position the lining and hold it in place at
one end by means of clamps. Using the holes in the shoes as guides, drill holes of the
correct size for the rivets adjacent to the clamp. Turn the shoe over, and counter-bore
the holes just drilled sufficiently deep so that the rivet heads will stand below the
lining surface; this is important, since the rivets will otherwise score the brake drum.
Insert the rivets into the holes and rivet them over on the inside of the shoe.
This is easily accomplished by holding in a vice a short length of rod, whose diameter
is equal to that of the rivet head, and using it as an anvil upon which to rest the rivet
head while hammering the shank over. This will also make sure that the rivets do not
stand proud of the lining.
Move the clamps to the next pair of holes, taking care that the lining is kept in
firm contact with the shoe the whole time, and repeat the above procedure. When the
lining is finally riveted down, bevel off the ends of the linings and file off any local
high spots.
Complete relined brake shoes are available through the Exchange Replacement
Service which operates in the British Isles only.
FRAME AND FORKS
Forks
(D1)—There is no adjustment for the telescopic forks fitted to this model. The only
maintenance required, apart from the routine check-up on the tightness of nuts and
bolts, is regular lubrication of the fork sliding members via the grease nipples
attached to each fork leg as indicated on page 19.
Application of the grease gun to these nipples charges the annular space between
the fixed outer member and the sliding inner member of each fork leg, and several
strokes of the grease gun should be given every 1,000 miles in order to ensure that the
supply of lubricant is maintained.
Protective Gaiters
These are fitted to prevent the entry of foreign matter into the moving parts and are a
PUSH-FIT
on the fork tubes. Periodically remove these gaiters, cleaning and greasing
the sliding members.
