4.1.5 Wheels and Brakes

f

Wheel Brakes
Each main wheel is equipped with a hydraulically actuated disk brake controlled by a hydraulic
cylinder mounted to the hinged top portion of each rudder pedal. These “toe brakes” can be used
collectively to slow the aircraft when on the ground, or individually to steer the aircraft.
Hydraulic Parking Brake
The braking system features a hydraulic parking brake accessible by a lever just above the floor-
board on the left sidewall in front of the pilot’s seat.
To set, apply pressure to both brakes via the pedals and hold, then move the lever to the “ON”
position. The pedal pressure can then be released and the parking brake will hold the set level of
braking.
CAUTION
:
The parking brake is intended only for short-term use (<10 minutes)
while completing tasks such as folding/unfolding the wings. Never
leave the aircraft unattended with just the parking brake set.
To release the parking brake, move the lever to the “OFF” position.
