Figure 4-13 Brake
circuit
!
To remove the leaf-spring struts proceed as follows:
Remove cabin seats by sliding them forward
Hoist aircraft onto supports
Disconnect brake fluid line unscrewing the upper link of the external line tract near fuselage bottom. Place temporary caps
on lines to prevent spillage
Loosen bolts (part.5 fig. 4-12) of the aluminum clamp (part 4 fig. 4-12) that secure spring-leaf to edge of main girder
Remove bolt connection between inboard end of spring-leaf (part.6 fig. 4-12) and main girder
Remove gear strut by pulling outward from fuselage
Reinstall using reverse procedure. It is however necessary to eliminate any trapped air: once the circuit is closed and fluid
in reservoir is at normal level, bleed air through dedicated valve. For best results, use external pump to push fluid through
valves allowing trapped air to escape through open reservoir.
If braking action appears degraded, check and eventually replace main gear brake pads
Refer to Periodic Inspection Chart in Section B for any service operation to main gear
