Brake system
O O 21 Inspect brake assemblies for general condition.
O O 22 Inspect master cylinders for leaks.
O 23 Inspect brake lines for leaks, bulges and deterioration.
Inspect brake lines for kinks, especially in the extreme
positions of pedals. Inspect brake lines for chafing,
especially in lead-through areas.
O 24 Lubricate anchor bolts using Silicone-base lubricant.
O O 25 Visually inspect the brakes for corrosion, cracks, or other
visible damage. Inspect inlet fitting bosses and anchor bolt
lugs for cracks.
O O 26 Check back plate attachment bolts to insure they are
properly torqued and have not worked loose. Gaps between
the back plate and cylinder would be evidence of this.
O O 27 Check fit of brake cylinder anchor bolts in torque plate
bushings for sloppiness. This can be accomplished by grasp-
ing the cylinder and moving it; slight movement is normal.
Excessive movement is cause for removal and detailed
inspection.

edges. Lining worn to a minimum thickness of 0.100 inch
(2.54 mm) must be replaced.
O O 29 Visually check torque plate for corrosion, cracks, loose
anchor bolt bushings, or other visible damage. Anchor bolt
bushings must be flat against torque plate surface.
O O 30 Check for any brake fluid leaks.
O O 31 Check brake fluid level (fill as required).
Steerable tail wheel landing gear
