Brake system
O O 1 Inspect brake assemblies for general condition.
O O 2 Inspect master cylinders for leaks.
O 3 Inspect brake system plumbing for leaks and hoses for bulges
and deterioration.
O 4 Lubricate anchor bolts using Silicone-based lubricant.
O O 5 Visually inspect the brakes for corrosion, cracks, or other
visible damage. Check inlet fitting bosses and anchor bolt lugs
for cracks.
O O 6 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 7 Check fit of brake cylinder anchor bolts in torque plate
bushings for sloppiness. This can be accomplished by grasping
the cylinder and moving it; slight movement is normal.
Excessive movement is cause for removal and detailed inspec-
tion.

the edges. Lining worn to a minimum thickness of 0.100 inch
(2.54 mm) must be replaced.
O O 9 Visually check torque plate for corrosion, cracks, loose an-
chor bolt bushings, or other visible damage. Anchor bolt
bushings must be flat against torque plate surface.
O O 10 Check for any brake fluid leaks.
O O 11 Check brake fluid level.
