the calipers. This keeps the brakes ON. The pressure will reduce in time and the brakes will slowly
release. A serviceable parking-brake valve will keep the brakes on for more than 1 day.
(1) Co-Pilot’s Brake Operation
When you press on the co-pilot’s right brake pedal these things happen:
) The connection to the reservoir is cut off by the initial movement.
) Further movement pushes fluid past the piston on the pilot’s master cylinder.
) The fluid flows through the parking-brake valve to the right brake caliper.
) The fluid pushes the piston and the pressure plate against the brake disk.
) The reaction force on the caliper pulls the back-plate against the brake disk.
) The right brake is applied.
In the same way, when you press on the co-pilot’s left brake pedal, the left brake is applied.

(2) Pilot’s Brake Operation
When you press on the pilot’s right brake pedal, these things happen:
) The connection from the co-pilot’s master cylinder is cut off by the initial movement. (Note:
Any hydraulic pressure from the co-pilot’s master cylinder pushes on the back of the piston
in the pilot’s master cylinder. This increases the brake pressure).
) The fluid flows through the parking brake valve to the right brake caliper.
) The fluid pushes the piston and the pressure plate against the brake disk.
) The reaction force on the caliper pulls the back plate against the brake disk.
) The right brake is applied.
In the same way, when you press on the pilot’s left brake pedal, the left brake is applied.
Note: If one side of the system fails, one or both pilots can loose braking on that side. For
example, a leak in the pipe between the co-pilot’s and the pilot’s right master
cylinder will cause a right brake failure for the co-pilot. The pilot’s right brake will
operate correctly. If the leak is between the pilot’s right master cylinder and the right
brake caliper, both pilots will have right brake failure.
(3) Parking Brake Operation
To apply the parking brake:
) Press on both pedals.
) Move the parking brake lever to LOCK (fully up).
) Release your foot pressure on the pedals.
) If necessary, pump the brake pedals.
To release the parking brake, move the lever to RELEASE (fully up).

Trouble-Shooting
1. General
Use the data below to trouble-shoot the wheel and brake system.
Complaint Possible Cause Remedy
Too much tire wear. Incorrect toe-in. Adjust the toe-in. Refer to
Section 32-10.
Incorrect inflation pressure. Correct inflation pressure.
Too much axial play in a wheel. Main wheel incorrectly
adjusted.
Defective wheel bearing.
Adjust the main wheel.
Replace the wheel bearing.
Brake disk distorted. Brakes applied too hard.
Hard landing.
Replace the brake disk.
Brakes do not hold static
engine run-up with the usual
pedal force.
Brake fluid level low.
Air in the brake system.
Defective master cylinder.
Defective caliper.
Worn brake linings.
Leaking connector.
Fill the system with brake fluid.
Bleed the brake system.
Replace the master cylinder
and then bleed the brake
system.
Replace the caliper and then
bleed the brake system.
Replace the brake linings and
then bleed the brake system.
