BRAKE SHOES
The front and rear brake shoes and springs are interchangeable. The two shoes in each
brake are N O T 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. By inserting washers under a thrust pin its
effective height can be increased, thereby compensating for wear on the brake linings.
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 cairn to
occupy a position whereby the available leverage is considerably reduced and, as a result,
the brake loses efficiency. See illustrations 37 and 38.
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. Eight of these washers
(000174) are provided in the tool kit. When wear of the brake linings is taken up in
this manner it is then necessary to unscrew considerably 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 afterwards.
