.
When the pedal is depressed the
primary and secondary brake shoes
are forced against the rear brake
ary pedal 'mouni. A spring-loaded
pawl and a release lever are assem-
bled to the pedal. A ratchet is as-
sembled to the upper end of the
pedal. The pawl contacts the ratchet
at such an angle that the ratchet
teeth will slide over the pawl as the
pedal is depressed; however, when
the applying motion stops and the
pedal starts to release, the pawl en-
gages the ratchet and thus locks the
brakes in the applied position.
When the manual release lever is
pulled back (Fig.
32),
the cam ac-
tion of the lever on the pawl cam
pin will disengage the pawl from the
ratchet to release the brakes.
