brake quickly get destroyed, owing to the intense fric-
tion. On a machine fitted with rim brakes it is essential,
for smooth braking, that the wheels should always be
kept perfectly true, as otherwise a faulty braking surface
is offered, and the brakes act in a “ hit-and-miss ” style.
Another disadvantage of the rim brake is that the rim
soon looks untidy in the paths of the brake blocks, this
applying to plated and enamelled rims, and not, of course,
to aluminium ones.
The “New Departure” (Figs. 49 and 50) is one of
the earliest and best known of coaster hubs. The
brake is self-contained in the hub, and is applied by a
very slight backward pressure upon the pedals. The brake
consists of three steel rings which are forced against the
shell by means of an internal mechanism. A good fea-
