Thrush Non-Asbestos Organic Linings; Brake Removal And Disassembly; (Cleveland Disc Type, See Figure 6-7) - Thrush Aircraft S2RHG-T65 TURBO THRUSH Maintenance Manual

THRUSH AIRCRAFT INC – MODEL S2RHG-T65 TURBO THRUSH
Properly conditioned linings will provide many hours of maintenance free service. A
visual inspection of the brake disc will indicate the lining condition. A smooth surface,
one without grooves, indicates the linings are properly glazed. If the disc is rough
(grooved), the linings must be reglazed. The conditioning procedure should be
performed whenever the rough disc condition is observed. Light use, such as in taxiing,
will cause the glaze to be worn rapidly.

THRUSH NON-ASBESTOS ORGANIC LININGS

A. Taxi aircraft for 1500 feet with engine at 1700 rpm applying brake pedal force as
needed to develop a 5-10 mph taxi speed.
B. Allow the brakes to cool for 10 – 15 minutes.
C. Apply brakes and check for restraint at high static throttle.
conditioning is complete.
D. If brakes cannot hold aircraft during static run-up, allow brakes to completely cool
and repeat steps A through C.
Due to the efficiency of these brakes, extremely hard braking
on aircraft with tail wheels could result in lifting the tail from
the ground, creating a nose over condition.
Use extreme caution to prevent aircraft from nosing over
when running engine at high static throttle (power lever)
settings, hopper and fuel system should be full to help keep
aircraft from nosing over.
This conditioning procedure will wear off high spots and generate sufficient heat to
create a thin layer of glazed material at the lining friction surface. Normal brake usage
should generate enough heat to maintain the glaze throughout the life of the lining.
Properly conditioned linings will provide many hours of maintenance free service. A
visual inspection of the brake disc will indicate the lining condition. A smooth surface,
one without grooves, indicates the linings are properly glazed. If the disc is rough
(grooved), the linings must be re-glazed.

A. Release parking brake.
B. Jack aircraft as outlined in Section II.
