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.
