BRAKE OPERATING SYSTEM DESCRIPTION
The brake effect is activated when the brake cylinder of the reduction gear is moving. It moves when the
parking brake pedal or the brake pedal is pressed.
When the brake pedal is pressed the oil moves the wheel cylinder which, by pressing against the side surface
of the reduction gear, moves the wheel brake cylinder. This turns around the fulcrum and presses against the
brake pin that pushes the pad. The pad pushes the main piston that closes the brake disks, obtaining the
braking effect.
When the brake pedal is released the springs push the main piston in the neutral position, freeing the disks.
The same movement around the fulcrum is obtained by pulling the parking brake lever that moves the brake
cylinder mechanically.
