hub barrel).
Re-fit brake cover plate with shoes, etc. and, if a rear wheel, also re-fit the speedo-
meter drive gear box and the central spindle.
The wheel is then ready for fitting to machine.
Note : —
In the case of the front brake cover plate it is most important this is correctly
positioned.
It is retained to the front wheel spindle by an inside nut (part number 40-G12M-
H47), and an outside nut (part number 013483). Between the inside nut and
the brake cover plate is a locating washer (part number 11913).
The inside nut should be positioned so that, when the locating washer is placed
next to it, the outside face of the washer is z" proud of the outer edge of the
brake drum. (Tested by placing a straight edge across the edge of the brake drum).
The outside nut must be correctly fitted, hexagonal side against brake cover
plate.
86 BRAKE SHOES
The front and rear brake shoes, springs and expanders are interchangeable. The two
shoes in each brake are NOT identical, they are " handed."
One end of each shoe bears on a fulcrum fixed in the brake cover plate. The other end
accommodates a detachable thrust pin. (See Para. 87).

87 BRAKE SHOE ADJUSTMENT

Brake adjustment, to compensate for lining wear, is normally made by means of a finger
adjuster on the rear brake rod and a cable adjuster for the front brake cable.
After a very considerable mileage this continual adjustment causes the brake expander
cam to occupy a position whereby the available leverage is considerably reduced and
as a result the brake loses efficiency. (See Paras. 90 and 91 also Illustrations 25 and 26).
To overcome this a hardened headed thrust 'pin is fitted to each shoe to enable a
packing washer to be fitted under the head as and when required.
washers STD-174 are provided in the tool kit. When wear of the brake linings is
taken up in this manner it is then necessary to considerably unscrew the adjusting nut
on the rear brake rod, or screw in the cable adjuster of the front brake cable, and
afterwards adjust the brake as described in Paras. 90 and 91.
When a brake cover plate has been disturbed, it is advisable, upon re-assembly, to
centralise the shoes in the brake drum to ensure equal pressure to each.
of the front wheel this is best done before re-fitting the wheel to the machine, but
in the case of the rear wheel it is best done after refitting.
(More than this quantity may result in brake inefficiency).
