MAINTENANCE MANUAL EXTRA 330LX
Tires
O O 20 Visually inspect tires for cuts, flat spots, and tread or side-
wall damage. If changing of tires is necessary, follow the
instructions, including off-aircraft inspection of wheels,
presented in the Cleveland Wheels & Brakes Component
Maintenance Manual.
O O 21 Check inflation pressure (3.4 bar /49 psi). Proper inflation
will provide maximum tire and wheel life.
Brake system
O O 22 Inspect brake assemblies for general condition.
O O 23 Inspect master cylinders for leaks.
O 24 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, espe-
cially in lead-through areas.
O 25 Lubricate anchor bolts using Silicone-base lubricant.
O O 26 Visually inspect the brakes for corrosion, cracks, or other
visible damage. Inspect inlet fitting bosses and anchor bolt
lugs for cracks.
O O 27 Check back plate attachment bolts to insure they are prop-
erly torqued and have not worked loose. Gaps between the
back plate and cylinder would be evidence of this.
O O 28 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.
O O 29 Visually inspect brake linings for extreme chipping on the
edges. Lining worn to a minimum thickness of 0.100 inch
(2.54 mm) must be replaced.
O O 30 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.
