The brake effect starts when the wheel brake cylinder
is moving. The brake cylinder presses the free cylinder
and the pad. The pin is used in order to block the pad
that otherwise would turn with the brake disks.
The pinion turns on gear group 2 where gear group 1
and the brake disks are fixed.
The brake disks have a tooted shape on the external
diameter in order to block them on the reduction gear
body. The counter disks have a tooted shape on the
internal diameter in order to block gear group 1.
Consequently, after pressing the brake pedal all the
disks are pressed and gear group 1 is stopped by
means of the counter disks. The springs are used to
retrieve the neutral position of gear group 1.
