The brakes do not require adjustment of the lining surfaces.
To bleed the brake system
1. Fill the reservoir with fluid.
2. Remove the bleeder screw from fitting on one side only of the
wheel brake assembly and place finger lightly over the hole.
3. Have someone operate the brake control to full on" then hold
finger over hole firmly and return control to "off" position.
Allow a few seconds for the fluid to flow into the master
cylinder and repeat the operation several times. Be sure to
keep the reservoir full during this operation.
4. Install the bleeder screw.
5. Remove the bleeder screw from the other side and repeat
operation (3)
6. Install the bleeder screw.
7. Continue bleeding until brake has a solid feel when applied.
Note: Do not allow hydraulic brake fluid to get on linings. Wash
clean with carbon tetrachloride or naphtha.
CONTROL SYSTEM
To Check Control System Alignment:
1. Neutralize the control wheels and check the control mast
under the baggage compartment to be sure the arms are also
neutral.
2. This should place the ailerons in line with the wing airfoil
section.
3. In neutral, the nose wheel should also line up straight with the
centerline of the airplane.
4. Now check rudders (everything inneutral) using two
straightedges paralleling the fin. Both should be straight.
5. Elevator limits are fixed by contact of a stop ring placed on the
control wheel tube with the instrument panel and should
permit 13⁰ ± 1⁰ up travel. The up travel of the elevator is
controlled by a turnbuckle which is sealed at the factory with a
