PARKING BRAKE CALIPERS - Forces brake pads against rotors when hand lever is applied.
PARKING BRAKE CABLES - Connects parking brake hand lever to equalizer bar.
EQUALIZER BAR - Evenly distributes braking pressure to the rear brake rotors.
PARKING BRAKE ROD - Connects parking brake hand lever to equalizer bar.
PARKING BRAKE HAND LEVER - Permits operator to engage the parking brake.
