individually activated by floor mounted toe pedals at both pilot stations.
A parking brake mechanism holds induced hydraulic pressure on the
disc brakes for parking. The brake system consists of a master
cylinder for each rudder pedal, a hydraulic fluid reservoir, a parking
brake valve, a single disc brake assembly on each main landing gear
wheel, temperature sensors, and associated hydraulic plumbing and
wring.
Braking pressure is initiated by depressing the top half of a rudder
pedal (toe brake). The brakes are plumbed so that depressing either
the pilot’s or copilot’s left or right toe brake will apply the respective
(left or right) main wheel brake. The reservoir is serviced with Mil-H-
5606 hydraulic fluid.
Brake system malfunction or impending brake failure may be indicated
by a gradual decrease in braking action after brake application, noisy
or dragging brakes, soft or spongy pedals, excessive travel, and/or
weak braking action. A temperature sensitive resistor is mounted to

each brake assembly which transmit signals via the Engine Airframe
Unit to the Engine Indicating System for brake temperature caution/
warning annunciation.
Should any of these symptoms occur, immediate maintenance is
required. If, during taxi or landing roll, braking action decreases, let up
on the toe brakes and then reapply the brakes with heavy pressure. If
the brakes are spongy or pedal travel increases, pumping the pedals
may build braking pressure.
Refer to Section 10, Safety Information, for Brake System operational
considerations.
Parking Brake
• Caution •
Do not set the PARK BRAKE in flight. If a landing is made with
the parking brake valve set, the brakes will maintain any
pressure applied after touchdown.
The main wheel brakes are set for parking by using the PARK BRAKE
handle on the right side kick plate near the pilot’s right knee. Brake
lines from the toe brakes to the main wheel brake calipers are
plumbed through a parking brake valve. For normal operation, the
handle is pushed in. With the handle pushed in, poppets in the valve
are mechanically held open allowing normal brake operation. When
the handle is pulled out, the parking brake valve holds applied brake
pressure, locking the brakes. To apply the parking brake, set the
brakes with the rudder-pedal toe brakes, and then pull the PARK
BRAKE handle aft.

Baggage Compartment
The baggage compartment door, located on the left side of the
fuselage aft of the wing, allows entry to the baggage compartment.
The baggage door is hinged on the forward edge and latched on the
rear edge. The door is locked from the outside with a key lock. The
baggage compartment key will also open the cabin doors.
The baggage compartment extends from behind the rear passenger
seat to the aft cabin bulkhead. The rear seats can be folded forward to
provide additional baggage area for long or bulky items.
Four baggage tie-down straps are provided to secure baggage and
other items loaded in the baggage compartment. Each strap assembly
has a hook at each end and a cam-lock buckle in the middle. The hook
ends clip over loop fittings installed in the baggage floor and in the aft
bulkhead. The tie-down straps should be stowed attached and
tightened to the fittings.
• Caution •
If not adequately restrained, baggage compartment items may
pose a projectile hazard to cabin occupants in the event of
rapid deceleration. Secure all baggage items with tie-down
straps.
To install tie-down strap:
1. Position straps over baggage. Thread straps through luggage
handles if possible.
2. Clip hook ends of straps over loop fittings.
3. Grasp the buckle and pull the loose strap end of each strap to
tighten straps over contents of baggage compartment.
To loosen tie-down straps:
1. Lift buckle release and pull on buckle to loosen strap.
2. Lift hook ends free of loop fittings.
